Who makes the best aluminium sliding patio doors?

Aluminium sliding patio doors are widely available in PVCu, aluminium, timber, or Hybrid doors using a combination of aluminium and timber. But who makes the best aluminium sliding patio doors? We look at some of the many aluminium sliding patio door options available and offer some guidance and advice.

What defines the best aluminium sliding patio doors?

Despite bifolding doors being the dominant and most desirable product for the home, sliding doors are back.  Sliding doors are better than ever. Today’s aluminium sliding doors offer the best aesthetics, superb long-term performance, security and weather resistance.  Modern patio doors are thinner and, in the case of the latest minimalist sliding doors, technically excellent.

There is plenty of content on this website about bifolding doors vs sliding doors giving you valid reasons to consider both. If your view through the glass matter most, choose a sliding door. If opening up your home to the outside in the summer is important, choose a bifolding door.

The Sliding Door Systems.

There can be much confusion about who makes the best aluminium sliding patio doors as door suppliers fall into several categories. These are:

  • The manufacturer and installer offering one or more systems.
  • The exclusive manufacturer with a dealer network of installers. Nobody else makes their doors.
  • The manufacturer that takes a widely available system and re-brands them as their own with or without enhancements.
  • The local door installers that buy in their doors from the producers.

In many cases, it does not matter who makes your doors or where they have come from. There is a benefit in buying doors from manufacturers that have taken the time and significant investment to bring out their brand of door. These doors are installed by a quality network of Accredited Installers getting a tremendous amount of training and support from their manufacturer.

Origin is an excellent example of such a manufacturer and has introduced their new Inline Sliding Door. Everglade Windows is another with their air 500 inline and air 600 lift and slide doors. There is also Arkay windows with their superb Infiniglide 3 and Infiniglide 6. Infiniglide 3 is the Cortizo Systems.  Infiniglide 6 is the Orama product from Greek Systems Company, Exalco.

Everglade Windows, Express Bifolding Doors, Dutemann, Dekko Windows, , Alufold Direct, Sunflex, Arkay Windows, Duration Windows and many others are examples of great aluminium manufacturers that use standard systems with minor or significant enhancements sold under different brand names.

Other specialist manufacturers work in close collaboration with well-respected European systems and have adapted them for the UK market with great success. Cortizo is a good example of a Spanish company and we’ve reviewed their minimal framed sliding doors in the UK under a number of brands.

Our advice is, be satisfied with the product, the price and the company providing it. It does not matter if the door is rebranded.

Sliding Door design, security and weather performance.

Virtually all sliding door manufacturers and installers demonstrate safety and weather performance of their doors through published test reports. Ask to see these to establish the security and performance credentials of sliding doors.

So who makes the best aluminium sliding patio door?

There is no ‘bad’ system on the market. All aluminium sliding doors sold in the UK today share four common characteristics.

  • The aluminium extrusions produced to recognised British and European Standards for conformity and type.
  • Approved applicators apply the powder paint finish to recognised British and European Standards.
  • Gaskets, seals and components also meet recognised industry standards.
  • Sliding doors are tested to established security and weather tests and standards.

Beyond the paint and materials, doors are designed and engineered differently, hence the various price points. Sliding doors will vary in their technical characteristics, quality of the running gear, components, handles and locking systems. Some doors enable you to customise them to meet your needs. Others are standard doors with only colour choices available.

The Sliding Door Brands

The is no best sliding door on the market because of their design, configuration, the method of opening and intended use.

Available are sliding doors to meet a simple door requirement, right up to specialist doors with structurally bonded glass, supreme strength and sliding door panels nearly 30 square metres each.

What we can tell you is who has the ‘best’ sliding doors by brand perception, reputation and their perception within the door industry. Some sliding doors are very much the choice of builders thanks to their price point. Other systems architects and discerning clients favour for their technical ability and overall quality. Above all the best sliding door is the one that meets the needs of the customer.

Origin is one of the best known names and now as popular for it’s sliding doors as its bifolding products.  Their latest OS-77 and OS44 patio doors come with high quality components and the legendary Origin manufacturing quality.  Also available is the OS-20 Artisan sliding door with 20mm sightlines and a structurally bonded construction.

Also, consider the benefits of using a sliding door supplier with bifolding door expertise. For instance, SUNFLEX UK offers arguably some of the best bifolding doors on the market. SUNFLEX is also one of the best known names in patio doors as well. Their German-engineered, sought-after bifolding doors come in several different types and their sliding patio doors are excellent too.

Sunparadise Systems provides a unique product proposition with their sliding doors and especially the Thermoslide 80. This excellent sliding door has a European design and has the ability to not only have panels move around a corner but also hide behind a wall or other panel. Do check these doors out – they’re quite different from conventional sliding doors on the market. At the same time they come with a quality build, high-end components and an ideal contemporary door solution.

Also worthy of consideration at the luxury end of the market are the highly distinctive sliding doors by Maxlight based in London. Slim, highly-engineered and with impressive aesthetics. Maxlight has its own sliding door system as well as some impressive pivot doors, box windows and roof glazing in its collection.

The air range of sliding doors are featured on this website and available though a quality dealer network in the South of England. A 25 year warranty and made by Everglade Windows, one of the longest established aluminium manufacturers in the UK.

IQ Glass based in Amersham with their Sieger brands is another standout architectural glazing business offering cutting edge sliding doors in a variety of styles, capabilities and technical performance.

Another outstanding sliding door is the Dutemann Glide-S. A high tech lift and slide door with impressive engineering and made by an award-winning manufacturer. The Glide-S is one of the few doors on the market capable of going over 6m wide with just two panels.

It’s also worth mentioning the sliding door products from Express Bifolds. While these are marketed under different brand names they are made with systems such as Smart Systems, Schuco, Reynaers, Metra and the Alumil system also available as the Dutemann Glide-S

This website considers the following Sliding Door Brands to be the market leaders for design, build, quality and service levels.  Prices vary as a  result.

We do not consider any doors on the market budget or low quality.  You get a reliable sliding door regardless of the system when well made and correctly installed.  Where they differ is the performance, the quality of the components and the overall quality of the slide action.

How to find the best aluminium sliding patio doors.

Any of the above doors as well as the many others not mentioned will give you peace of mind in being well made and installed. If you have been quoted the above or an alternative brand and need further information on it, contact us.

The above systems include both standard sliding doors and the latest slimline, panoramic and minimalist sliding doors.

Some installers will tell you their sliding door is their own system. We would treat this statement with caution. To produce your own sliding door system requires vast sums of money in design, tooling and aluminium die production. Products need testing with technical/installation manuals creating. Bringing out a new sliding door is a long and expensive process reserved for the aluminium systems companies with Group or Parent Company backing.

Guarantees on aluminium sliding patio doors.

The guarantees on sliding doors vary depending on the system and the manufacturer. Typically you can expect to get ten years on the entire installation, although so manufacturers will only offer five years on the glass.

Origin remains a leader in product warranty with a 20-year guarantee on either the entire product or elements of it. Everglade Windows in another, providing a 25-year guarantee with their air sliding doors when purchased through an authorised retailer.

The fact that some doors do not have the guarantee offered on Origin and Air doors does not make them inferior. The companies that are the sole manufacturers of their product have more control over their processes. Every door is consistent in quality. The availability of their doors through a dealer network also means they have trained their dealers to fit them correctly. A more extended warranty is therefore provided.

Don’t be afraid to ask questions about your sliding doors.

If who makes and who is behind your new sliding doors matters in your buying decisions you may want to do your research. Ask your supplier where the extrusions come from, what is the name of the system and who extrudes the profiles.

Your sliding door guarantee will also depend on who fits them. Many homeowners choose to leave the sourcing and fitting of a sliding door to their builder. If the door has come from a trade supplier, a limited warranty only is available. If you plan on having your builder fit your doors find out what guarantee you will get.  You may find it better to get the doors installed by the door company instead.

Service levels influence the best aluminium sliding patio doors.

As an independent and impartial aluminium website, we can tell you that the best sliding door depends on who makes it and who installs it.

We often hear from homeowners concerned that we have suggested a particular system to them, only for others to tell them it is not good.

At the systems company level, much work is done in designing a sliding door. It is extensively tested and improved before it is launched. Then the network of fabricators has to be trained by the systems company. Most installers buy sliding door systems from this network of manufacturers. If there is a fault with the product and they are not getting the support in putting it right, the perception exists that this is a bad door. There is no bad door on the market.

Maximum and minimum sizes of sliding doors

A sliding door enables bigger door leaves than any hinged or folding door. You benefit from bigger glass panels and more light. With most quality systems you can expect each sliding panel to accommodate 3 metres on the width and the height easily. For most houses, the extra height will not matter, but you have peace of mind that the engineering behind your sliding doors creates impressive spans.

Other sliding door systems are standardised at 1200mm modules on the width and 2500mm on the height. These are again great doors and should not be perceived as inferior because they are not possible as tall. Take a look at impressive products like the Dutemann Glide-S capable of spanning more than six metres with just two panels.

The Sliding Door Interlock.

As you do your research on finding the best aluminium sliding patio doors for you, you may come across the interlock. When sliding doors meet when closed, the back of the inside door meets the front of the outside panel, creating a vertical mullion. This is the interlock.

Sliding doors have slimmed down substantially compared to previous generations, now providing you with interlocks from 35mm right up to 110mm or more.

The latest generation of slimline and minimalist sliding doors offers interlocks from 20mm. The compromise with these thin interlocks is that they need to go very deep, providing structural integrity to the door. Visually a narrow interlock on a sliding door has an aesthetic advantage. Our point of view is that it may matter on a narrow sliding door having two panels but is not so important on wider the doors.  The thicker interlocks spaced farther apart appear less obviously on a wider set of doors.

Sliding door hardware and quality.

One of the first signs of quality on a sliding door is the sliding action. Even large and heavy doors owing to size should be easy to open. A positive feel to the door is your first clue that it has quality components.

The design of the door handles, especially on a lift and slide door cleverly lifts the doors away from the frame ready to slide. These should feel precise and with a premium look and feel.

The function of the door handle on some products limits colour choices as a result.

Inline vs lift and slide patio sliding doors.

The two main methods with which sliding doors operate is the inline or lift and slide method. We offer an explanation of inline vs lift and slide to help you understand how these doors operate. As a general rule, the new minimalist sliding doors are inline.  Other patio doors available either inline as well as lift and slide.  Go try both sets of doors out and you will see how they work and the benefits of each type of sliding door.

    Hi there, we are looking for someone to manufacture a 9m run of sliding doors with 3 x 3m panels. We want the ability to move any of the 3 panels independently so that you could walk out to the garden through either the left hand panel, centre panel or right hand panel. Equally we would like the ability to stack all 3 panels on either side. Does anyone know of a system like this? Many thanks for the help!

  4. Hannah Goddard says

    Hi a bit of advice or suggestion wld be appreciated. We’re putting in sliding doors 3.38m wide in back wall of our home; having knocked down wall between kitchen and dining room, and making one large space. Also hopefull having patio immediately outside and would like level entry between inside and outside. My concern is thermal values and appearance. Back of house is north/ north east facing, and we have an oak tree either side of garden. If this room/ space is to be used well it needs to be comfortably warm and with a clear view out. Thinking 3 sliding doors, all moveable. Also need good security. Getting overwhelmed by choice and want what’s best for our situation, as opposed to just builders recommendation … not that that could be perfect for us, but just don’t want his supplier just because that’s what he is, builders supplier. Any suggest would be appreciated.
    Regards

    • Nick Dardalis says

      Hi Hannah, get in touch via our contact form with your location and I can try put you in touch with some suppliers to help you. All the good brands of doors in combination with the right glass specification should serve you well but it might be a case of exploring more suitable glass rather than the doors themselves. There are some two panel doors that comfortably go up to your overall width which would give you one less visible mullion and bigger glass.

      Security depends on the rating of the doors, the quality of the door cylinder and whether they have any anti-lift features which most do.

      Hope this helps

  6. Peter Smith says

    Hi, I live in Cornwall in an exposed position near the sea. I need to replace my old aluminium 3.6m wide two pane slider patio door but I get conflicting reports from installers which system is best, a two door Schuco aluminium system or a three door upvc system. the claim from some is that alloy systems are not good in the sort of wind/rain weather we get here, especially wind blown water in the drainage area, whereas upvc systems dont have that problem. Can you advise please.

  7. Adam Drysdale says

    Hi,

    Thank you for helping to clarify some of the mystery and options in this area.

    We are looking for 2 x 3000mm (width) x 2100mm (hight) sliding doors that will both recess into a central wall pocket.

    Do you know if most suppliers will provide their systems with extended tracks or is this limited to the likes of MaxLight?

    Any recommendations or tips.

    Many thanks again.

    Adam

    • Nick Dardalis says

      Hi Adam, Maxlight sliding doors are excellent and a very good company. Other systems will also achieve the extended track such as Sunflex, Reynaers, Schuco and others.

    Size is 4206mm (could be 4200 if standard size) x 2500mm high
    I’d prefer a slimmer sightline ideally 20 or 30mm mullions.
    Can you please recommend some mid range manufacturers and their suppliers in the Bath/Bristol area?

    What is considered a good U value for these types of doors?

    Thanks

    What an excellent article.

    We are wanting to install aluminium sliding doors for our house in Ilkley, West Yorkshire. The gap is 7.5m wide by 2.5m high. Ideally, we are wanting 3 panes and for each of these panes to move.

    Of the mid priced brands which do you believe would work with these dimensions / 3 pane option ? Also is there an installer you’d recommend reaching out to in the area?

    Many thanks,

    hi, looking for 2 pairs of aluminium lift and slide doors , 1 at 4.2 m and the other at 3.8m. Any help from you would be greatly appreciated. Great website by the way !! We are in Sheffield and need a supply and fit quote to pass building regs.

  11. Rosalyn says

    Hello again. I should have mentioned in my previous comment that the 4.5m width is three track and the two 3.5m sides are two track. Also require corner opening. Thanks

  12. Rosalyn Cross says

    Hi Nick. Just read through your very informative article and comments relating to inline sliding doors. Thought I knew a bit having done some research but there’s clearly lots more to learn!
    Please could I have your opinion on companies for sliders for our extension (glass 3 sides – 4.5 width x 3.5m depth by 2.4m height). I require solar controlled glass, flush threshold, 20-30 max mullions. Looked at Edge 2.0 from ID Systems, visited IQ Glass but too expensive for me. Any suggestions? Also just got in touch with Fusion Glazing – what do you think to their Fusion Visione or Sunvista Minimal? West Sussex location. Many thanks

    • Nick Dardalis says

      Hi Rosalyn, yes you’re looking at the structurally bonded systems other than the Edge 2.0. While the 20-30mm mullion is great to have, going a little wider extends the choice. And with a larger sliding door still looks slim.

      Therefore there are some products to consider and should work out cheaper than the systems you’ve looked at already, as good as these are.

      First is the new Origin OS-44 sliding patio door with a 44mm mullion. These look great with high quality BLU handles and all the quality associated with this great brand. There is also the OS-20 Artisan with the 20mm mullion and similar Cortizo doors.
      Then is the new Reynaers CP68 sliding door with a 41mm mullion and again Reynaers is an excellent system in the home.
      Sunflex SVG30 based on an improved Visoglide sliding door with a 30mm mullion.

  13. daniel says

    hi there ,
    would you recommend the SL18 Hyline Sliding Door System ? if you have to compare it to the co vision plus which one will you go for ? Thanks

    • Nick Dardalis says

      Hello Daniel, thanks for your question. The Hyline door is a Portuguese system available in a number of variants, with the 18mm being the slim version of this product. It’s a very well-engineered door with some good features and specifications and comparable with the Cortizo door. Both door systems meet similar specifications so I would look at the aesthetics of the two doors as they are different. But both are well-designed and should serve you well when properly made and installed. The Hyline is the more exclusive product as Cortizo is widely available in the UK both under the name and several other versions/rebrands of it.

      Hope this helps
      Kind Regards

  14. Paul Nasse says

    Hello Nick,

    Firstly, thank you for posting such an insightful article – it’s much appreciated and very helpful.

    I am current building an extension and have been looking into the world of sliding doors over the past couple of weeks. I never realised there was so much to think about!

    Having spoken to a number of suppliers and companies (inc. Reynears, Origin and Express) I am finding it incredibly difficult to find a system that will work for me and I was wondering if you could help point me in the right direction please?

    In short, I am looking to buy a 3 door sliding system that is 5000m (w) by 2600 (h). Ideally the system is on a triple track and has minimal sightlines, both on the interlocking mullion as well as the frame itself. The interlocking sightlines need to ideally be somewhere between 25 and 40mm – as we need the size to work with our blind system – Blindspace) I am also looking to have an equal/flush threshold going from inside to out.

    In my mind this should be relatively easy to find but I am having real difficulty. I have been warned that the system needs to be PAS 24 compliant for building control and my insurers have requested a multi-point locking system and when you put all this together I have come up short.

    Is there any supplier/company that you know of that I should look into please?

    Kind regards,
    Paul

    • John says

      Sorry could you explain a bit further why do you need 25 and 40mm sightline for the Blindspace to work for you? What is the connection of the blindspace with the sightline?
      Also, why are you finding it difficult to find a system from origin/raynears?

      • Nick Dardalis says

        Hello John, not too sure on your question – are you asking about integral blinds in sliding doors? If so, you need to be aware with some sliding door configurations that the magnets on the door can hit the frame. If it’s something different drop us a line and will try to help.

        • John says

          The question was for the original comment by Paul Nasse.

          I was wondering why the sightlines need to be 25-40mm for the doors to work well with the blindspace system!

  15. Philip Westwood says

    I was wondering if you could help

    We are looking to fit a 4000mm x 2100mm sliding door (four panels – middle to to open and slide over the outer two).

    It is for a garden studio so do not need a premium product or want to spend a fortune, and do not need it to be frame less etc

    I was wondering which make and/or model you would recommend for our purpose

    • Nick Dardalis says

      Hello Philip, thanks for your question. Any of the systems available will serve you well so it depends whether you are looking for any particular aesthetics, but Aluk sliding doors and Visoglide patio doors are great doors, well priced and should serve you well.

      Happy to put you in touch with a local installer if you’d like to get in touch via our contact form with your location.

    This has probably been one the most insightful and interactive articles and comments section i have ever seen. Well done.

    The question – i am looking for a lift and slide sliding doors where its a two pane solution which can centrally meet to fit a 6000mm by 2200mm.

    I’ve had several quotes but one i have had is for a (Alumil) S700. I cannot see much on this product but was wondering how you think it stacks up against the Dutemann and Schucco? There’s a decent price variation and i’m trying to understand if technically and qulaity wise there is much in it?

    I’ve also heard things about “type of aluminium” – mostly from the high end brands and i’m also wondering how much of this is a sales pitch or if its something which needs serious consideration (based on products needing to meet building regs)

    Thank you in advance

    • Nick Dardalis says

      Hello Suki, thank you for your comment and your kind comments on our website. Much appreciated and glad you like what we try and do giving information to homeowners and the trade across all products.

      The Dutemann Glide-S is the Alumil product so you’re getting pretty much the same door. This and the Schuco are comparable but it depends which model of Schuco as they have several sliding doors in their portfolio. Also worth looking at the new Schuco ASE60 or ASE80 which is reviewed on this website – a brilliant sliding door with excellent design and some clever features. You won’t go wrong with any of the good brands such as Alumil/Dutemann, Schuco, Reynaers, Air Doors. Solarlux make excellent doors as does Sunflex.

      There is also the new Origin OS-77 and OS-44 but these only come in two or three panels although up to your width. Worth checking these out too.

      Type of aluminium is probably a sales pitch. Aluminium extrusions need to meet specific industry standards for grade and quality and they all do. Where they differ is design, thermal performance, thickness of the powder coating – but the aluminium is similar across al products as a material. And most doors meet or exceed current building regulations.

      Happy to put you in touch with some suppliers if you’re presently getting prices if you’d like to get in touch via our contact form with your location.

      Hope this helps, please don’t hesitate to get in touch if you’ve any questions or need further information.

    Hello Nick

    looking at the posts it seems that the Express Glide-R products is the Reynaers CP130 system.
    We went to the supplier our builders want to use and they provide the CP130 system. We wanted to have the runners flush with the floor. Initially he thought it would need an additional piece of kit to do this whcih was a few hundred pounds. He has now come back after checking with the suppliers of the CP130 have and said we would need to install the Hi-Finity Aluminium Sliding doors to do this which is a significant increase in cost.

    Reading the Express Windows brochure they say they fit the sliding rail flush with each installation of the Glide R system. So am confused as to why this would be now I understand they are actually the same door

    Any thoughts on why this might be?

    • Nick Dardalis says

      Hello Antonio

      Have a look on the Reynaers website for the cp130 or the cp155

      https://www.reynaersathome.co.uk/wp-content/uploads/2019/06/101671-RAH-CP130-Brochure-compressed.pdf

      This shows a flush floor integration option which I understood is possible so I can only presume the supplier doesn’t offer the product for their own reasons, but it should be possible. I do know some manufacturers make decisions on what products they offer in what options so perhaps they’ve made a business decision that where someone wants a sliding door with a flush or low threshold it’s the Hi-Finity that business offers.

      I would have thought if the supplier your builder wants to use is an approved Reynaers manufacturer they should provide an explanation of why?

      I’ve also looked at the CP130 technical manual and this does show a low threshold option.

      If you’d like to get in touch via the contact form with your location I can try put you in touch with some alternative Reynaers suppliers. Express is an excellent company and you should wish to use them.

      Hope this helps
      Kind regards
      Nick

    Hi, thank you very much for producing such an informative website. I have a quick question if I may. I’m currently looking for a 3 panel sliding door system (4400mm x 2200mm, with no fixed panes). We really like the IQ Glass Minimal Windows System (Keller) but it’s a third more expensive than the Sieger sliding doors and we can’t justify the extra amount of money. Therefore we’re torn between Maxlight and Sieger, the only obvious difference we can see is that Maxlight appear to have a noticeable frame at the bottom of the system. Both are 20mm vertical sightlines, so I’m wondering if there are any other key differences at all? Also would you be able to recommend any other competing doors? Many thanks. Steve

    • Nick Dardalis says

      Hi Steve, both of these doors are excellent and the companies supplying them do very good work. It’s hard to comment on the retail prices of sliding and other doors as so many factors come into play. For instance, the obvious profit margins, whether they make or buy in the doors, other material costs and installation charges.

      Keller doors are outstanding but yes they are at the top end of the price range. Other than that they share similar specifications and construction will invariably have the same quality of powder-coated finish and glass.

      Therefore go with the doors you like the look of the most and of course the confidence in the company. Another good sign of a quality door is how smooth they are to slide and lock.

      Most of the other doors with a similar 20mm sightline are based on the Cortizo system such as the Origin inline slider, Air 20SL, Infiniglide Doors etc. Another one to consider is the product by Architectural Vision systems. They’ve taken the Cortizo door and done quite a lot of good work with it.

      Another one to look at is the Edge 2.0 by ID Systems/Sunflex. This also has the same sightline and might be another one to consider.

      Hope this helps, but you’ll get a great door whichever one you go with. Thanks very much for your kind comments on our website.
      Kind regards
      Nick

        Thanks Nick, a couple of options I hadn’t thought of there. Appreciate the feedback.

  19. Rachel Bainbridge says

    Thanks, this was an incredibly useful article. I am looking to buy sliding patio doors for our house in Weybridge. My builder has recommended using the Express glide R system. It looks good, my only issue is that we want the doors in white and the rubber trim that they use is black, which I think looks a bit odd. Would you be able to recommend any alternative suppliers in the area who do good quality doors what are all white? Thanks very much.

    • Nick Dardalis says

      Hello Rachel, thanks for your question and your kind comment. As far as I’m aware the Express Glide-R products is the Reynaers CP130 sliding door system. I’m not aware of anyone doing white gaskets on sliding doors and I’d suggest you stick to the black. While I appreciate a personal preference for white, given the size of the sliding door market and the sheer number of products on the market, a white gasket would have been addressed a while ago and more widely available. It’s also worth thinking about how white gasket ages over the years and you’ll find it looking dirty and tired-looking in the future. There are also technical reasons why black works better in the EPDM material used for door rubbers.

      If you’re looking at the express product, I can also suggest you look at the below.

      Schuco or Smart Systems Visoglide sliding doors that are slimmer than Reynaers.

  20. D Simpson says

    Hi, what a helpful and informative site! I’m hoping you can solve our present conundrum…
    We are currently looking for aluminium sliding doors, and having gone through what we’d assumed were the most important specifications from different companies had settled on express bifolding doors. However, we live in a stone farmhouse the colour of which is light fawn and annoyingly this crucial element has become a sticking point. It seems that there is no variant of this shade in the ‘ral’ classic chart, though i cannot believe the powder coating industry misses this market?? The ral design colours are better but apparently are unsuitable for powder coating. Can you shed any light on this please

    • Nick Dardalis says

      Hello, thanks for your question and your kind comments on our website. The choice of colours available is not limited to the RAL colour chart. There are Syntha Pulvin Colours, BS Colours, NCS colours as well as specialist textured, heritage and other very specialist shades. Then you have all manner of companies making the powder the applicators use to paint aluminium. These include Interpon Paints, Tiger, IGP, Axalta, Syntha Pulvin and others. So it might be worth you looking up a couple of tiers on the supply chain at these makers of the powder and asking them for the reference in the colour you want. I’m fairly certain it exists!

      Every door supplier buys their profile from the systems company already painted or they use independent powder coaters. These powder coaters offer the range they do, some a big range, others a restricted one. So it could be a simple case of Express not having access to this colour and therefore not able to supply it or not wanting the extra work involved in getting it for you.

      Obviously without seeing what you mean by ‘fawn’ there are so many different colours and textures available that you may have to look either at a special order or an alternative supplier, as good as Express are.

      There is also the option of Express (should they wish to) ordering your exact colour. You will have to pay for minimum powder quantities, minimum order charge quantities, but I see no reason why a good supplier cannot discuss your colour choice with the company painting their material and arrive at a solution for you.

      Hope this helps,
      Kind regards

  21. P Dout says

    Hi.
    This is a really helpful website. I’m looking for slim profile, high quality aluminium sliding door systems for an opening of 5844 wide by 3200 high. I’ve seem very few suppliers exceed 3m high so have a limited market.
    In addition, I’m looking for these doors to pocket into a wall so you have complete opening with no panels visible therefore might need a system that has an extended track perhaps. Ideally looking at low u values.

    Is anyone aware of a system that would be suitable?

    Many thanks for any advice.

    • Nick Dardalis says

      Thanks for your question. The Reynaers hi-finity door exceeds the 3 metres as do some other systems such as Panoramah and some of the cortizo doors. U-Values are low with these doors thanks to the substantial glass units and slim frames. If you’d like to get in touch via our contact form with your location, I can put you in touch with some local installers.

      Hope this helps,  
      Kind regards

  22. Dave and Catherine says

    Hi

    We are trying to understand what the real difference is between Smart’s Visoglide sliding doors (35mm) and the Sunflex SVG30 product – other than 5mm of frame width.

    One showroom told us that the “SVG” in Sunflex’s range stands for “Smart Viso Glide”’, because Sunflex rebrands the same core product?

    The Smart Visoglide system appears very similar to us yet is £3000 cheaper for a 7.6m x 2.3m four pane aperture.

    What might be the risks to us of going with the cheaper option?

    Many thanks for any advice,

    Dave and Catherine

    • Nick Dardalis says

      Hello Dave and Catherine.

      Sunflex makes no secret that it is the Smarts Visoglide (SVG = Smarts VisoGlide) product but they have re-engineered it. This re-engineered door is also widely used by companies such as ID Systems in high-end architectural glazing.

      As far as we know and we covered this in the review of the door, the enhancements are mainly improvements to the flush floor detail over the standard product and improved weather rating. You will also get neater caps at the end of the doors compared to Visoglide. Sunflex has also designed their own finishing trim you don’t get with other doors making the doors look better where they meet your floor and giving an improved clearance too. As well as this, they’ve changed the product to give a bigger clear opening than the standard Visoglide. Three panel doors are more popular than four so here Sunflex has again changed the doors making each of them a different size so when fully open they sit neater and look far better. Where external handle is fitted, the doors fully open and stack flush too.

      For those building a new extension and wanting their doors to disappear in to the wall when opening, again the standard Visoglode doesn’t look as good or as neat compared to what Sunflex has done with the door.

      So the best advice I can give you is go see the Sunflex door and compare it to the standard Visoglide. The other thing to do is also speak to someone at Sunflex directly and they can expand on the product further.

      So they don’t just rebrand a product – they’ve customised it as they need to provide a door at the same high standards as their German-made bifolding doors that are outstanding products in many ways. To design your own door costs vast sums so taking an established, tried and tested door and making it better is one way of having ‘your own door’ with none of the costs invovled in designing, testing, certifying and bringing a product to market.

      There are no risks with the cheaper option. The Visoglide is a great door – one of the best sellers. But Sunflex has just made it even better. Go see it.
      Kind regards
      Nick

      • Umran says

        Thanks so much for these helpful tips. I learnt a great deal from reading this article. Great work!

        I have few questions;

        We are doing an extension and will need sliding doors for 4m wide and 2.40 m high sliding doors for the living room and narrower versions for the kitchen, All opening to the patio. A company we found who is a Shuco dealer as well, is recommending Cortizo as being a cheaper and slimmer option. I am looking for floor channels not being deep. Being flush with the floor but Corrizo has channels which may fill with dirt. Of course I can clean them but wondering if there are solutions to this.

        How important it is to have trickle vent on sliding doors?

        I wanted slide and tilt but advised against it. What do you think? Whole idea was to air the room without completely opening the doors.

        My other concern is leaving the doors open in the summer and insects and mice getting in. It happened to us before so I am cautious. I asked around for sliding doors with fly screen but could not find any brand. Do you know an aluminium brand that does fly screens? I know that independent companies can fix fly screens over existing sliding doors but it seems silly that we can not do it all together.
        What would you say for. Cortizo ? Is it a good brand to have.? I had a quote from iQ glass for their own brand and it was 20% more expensive than. Cortizo.

        My last question is upvc versus aluminium windows. Our builder and architect advise upvc windows as they provide better insulation. However the window company says that the upvc is going to be extinct in the near future. I am concerned about upvc releasing toxic gas during hot days but they say that is not the case any more. What would you advise ?

        Thank so much for your valuable input in advance.

        • Nick Dardalis says

          Hi Umran, thanks for your question and I answered your other one regarding Hybrid doors.

          First of all trickle vents are not really a choice, they are part of current Building Regulations. So unless you’re making provisions elsewhere in the room for adequate ventilation then you will need them in your windows and doors.

          There are many different sliding doors on the market and Schuco are one of the best out there, but other good brands such as the brand new Origin OS77 and OS44 sliding doors, Air doors, Reynaers, Sunflex, Sunfold and many others.

          For brands that do Flyscreens check out Centor sliding and folding doors. These are one of the best brands and sure you’ll love them and they come with an integrated flyscreen system.

          Also, if you get in touch with Panoramic Group they have a slide and stack door that also comes with a flyscreen system you can retro-fit on any other door too. Your other option is to get in touch with a dedicated flyscreen company and simply fit these after the installation of your doors as you say.

          There is no bad door or window on the market but where they differ is who makes them, the overall supply chain and the quality of the installation. All the current systems should be designed to meet or exceed industry standards for weather performance and security, as well as the quality of aluminium and quality of paint finish. You won’t go wrong with a well-made and fitted door. Where products differ is aesthetics, sightlines, quality of components and brand perception.

          IQ glass offer some excellent products, but it’s hard to comment on the prices people charge for their products – of course based on specification, installation requirements, profit margins etc.

          Finally on aluminium vs pvcu. Pvcu windows today are substantially better with some outstanding flush casement windows from liniar, Residence 9, Deceuninck. Some such as the Deceuninck come with a near aluminium finish. Yes they are better insulated. For standard size windows and doors you’ll be fine with PVCu. For bigger windows, slimmer sightlines and a bigger choice of colours then aluminium is the way to go. That said, PVCu windows come with very good wood effect and plain foils with a very good look and feel. I don’t think PVCu windows will be extinct anytime soon for their affordability alone. And we have never heard of any emissions from windows so don’t think there is anything to worry about there.

          Hope this helps and answers your questions.
          Kind Regards
          Nick

  23. Iain watson says

    Hi, we are wanting a sliding window for a 4.5m wide, 1.5m tall opening in a two pane configuration (one fixed one sliding.

    We have been given an option of an Alumin Techno SL160 (BETA) system, and the quote seems quite reasonable. However I have found it very difficult to find any information on the quality level of the product, mainly because it seems Russian? origin and fairly new to the UK.

    Would this system be similar to any more familiar systems such as Smarts Visio glide Plus system?

    Any feedback would be much appriciated

    • Nick Dardalis says

      Hello Iain, thanks for your question.
      I think you mean the Alutech SL160 sliding door with the systems company from Belarus? We say throughout the website that there is no bad door on the market and any well made and (importantly) fitted door will be reliable.

      The SL160 is a new door, some consider it quite thick at the sight lines, but we’ve never heard anything bad about the product and we know that more and more fabricators are taking it on to make it. The company in the UK is based in Dewsbury and the Belarus company one of the biggest systems companies.

      If you like the door, if you are happy with the price and the company providing it for you, then you should be fine, but by all means get in touch with Alutech and they can put your mind at rest on it too.

    Hi Nick,
    Thanks for this valuable article.

    We are about to start a new build project and are looking for windows, fixed pane windows, external doors, and corner-less sliding doors for the house. Is there one firm you can recommend who can supply all of these? Or is it likely that we will need to go to different suppliers (I know many do not do corner-less sliding doors).

    We have used Fenster Uni-Slide for a past project but wonder what else is similar or slightly higher in quality, particularly performance-wise as these will be in a coastal location.

    Thanks in advance for any advice you can provide.

    • Nick Dardalis says

      Hi Hannah, thanks for your question.

      All the good sliding door brands do a cornerless solution.
      Schuco ASS70
      Reynaers Hi-Finity
      Sunflex SVG doors.

      If you’re happy with the Uni-Slide I see no reason why you can’t use these again, assuming you’re happy with your doors and the company should be able to customise these for a coastal location such as a proper guarantee on the paint finish by the powder coater, improved fixings etc.

      Any good supplier of the above products supplies windows, external doors etc whether from the same or other systems. If you’d like to get in touch via our contact form with your location, I try put you in touch with some suitable suppliers to get a quote.

    Thanks for the informative site. I’m considering slim profile sliding doors from IQ Glass and ID systems at the moment for a corner configuration. Do you have an opinion about which would be better? Are the security features on these makes essentially the same?

    • Nick Dardalis says

      Hi Boz, both good products from professional businesses supplying very good systems. I think you’ll be happy with either when correctly made and fitted. IQ offer a lot of premium systems as does ID. Go with the doors you like the look of the most, check out how they slide and, of course, confidence in the company you want to work with.

    • Nick Dardalis says

      Hi Andy. Not cheap, but very well engineered and a very good range of windows and doors indeed. If you like the product it’s a good one to have. Internorm tends to come with very expert window companies to with a lot of expertise and an overall premium range of products. They’re very good window overall if you’re happy with the specifications, sight lines, of course, the price and the company supplying it.

        Nick,

        Thanks for your reply. I went and looked at the Arkay Infiniglide 3 system. Was a bit surprised to find that the display units flexed (moved) from side to side in the track. Does this happen with all minimal frame systems.

        • Nick Dardalis says

          Hi Andy, if the door has a double or triple track and is configured for both panels to slide left and right, then yes this is normal and you have the option to have them moving in one direction only.

    I have read your informative article, I have been quoted for a 5m * 2.1m 3 sliding doors using a `Notus` . This was not on your list – can you pls advise.

    • Nick Dardalis says

      Hello Joe, I’m surprised anyone is still using the name Notus as this product was formerly the Beaufort System which is now AluK and not the same as the Notus. The nearest equivalent using the current Aluk range of sliding doors is the Optio BSC94 inline sliding door. However also worth checking whether they’re buying in the door from Europe as I believe the Notus name could still be used there?
      Hope this helps

    Hello Madeleine, the Ultraline brand is fine with nice modern looks and well made. If you like the product, the price and the company supplying it, you should be fine with this.

    The best way of finding out about the glass is to ask your supplier what glass manufacturer they use and from which glass producer. Pilkington, Saint-Gobain, Planitherm and typical suppliers many use and they should have no issue telling you who produces and then who makes the glass going in your doors.

    Hope this helps
    Kind regards
    Nick

  29. Madelaine says

    Do you have any experience of the Ultraline brand? They have a very slim profile all round.

    Separately one of the challenges of deciding between brands is the glass. How would you know if one product has better glass than another?

    Thanks in advance, its a mine field out there!

    Madelaine

  30. Nick Dardalis says

    Hello John. Thank you very much for your kind words.

    The Smart Systems Visoglide plus is a very good door and widely used. If you’re looking at this product can I suggest the Sunflex SVG30 it’s the same system but re-engineered in many ways and well worth considering? If you’d like to get in touch via the contact form with your location I can try put you in touch with a local dealer.

    The Express XP Glide R uses the Reynaers CP130 system. As far as brand perception and overall engineering of a product the Reynaers is widely regarded as the better system.

    As we say many times across the website, there is no bad door on the market. A correctly made and well-fitted door regardless of the system will serve you well. Where they differ is engineering, aesthetics, quality of components and brand perception. Reynaers is the more ‘premium’.

    No surprise the Smart Systems doors are cheaper but a perfectly good sliding door.
    Hope this helps

  31. John Gibson says

    Hi. Nick. Excellent resource. Thanks
    Between 2 options for a 3.6 lift and slide. 2 door.

    1/Smart video glide plus. Both doors opening with soft close. 35mm centre.

    2/ Express bi fold XP glide R. Single opening.. 69mm centre.

    Which is the better quality door.. The smart doors being nearly £1k less even with twin opening.

    Which system is the express door base on?

    Just some insight into whether the price difference is worth it in terms of engineering feel or durability.

    Please can you advise on the quality of Real Aluminium Sliding Doors a company based in Stonehouse Gloucestershire.
    We are currently looking for three sets of doors 1.6m, 2.2, & 2.6m widths with as narrow a profile as possible from a respected manufacturer within a budget of £12,000, Surveyed, supplied & fitted, is this achievable and what would you recommend.

    Any Assistance you can offer would be greatly appreciated.

    • Nick Dardalis says

      Hello Paul
      REAL aluminium uses the Smarts System, very popular sliding doors. Also worth looking at the SUNFLEX SVG30 which is the same product but re-engineered with added features and an improvement on the basic product.

      The budget is really down to getting prices from a number of suppliers for your project. If you’d like to get in touch via the contact form, I can put you in touch with a couple to get comparable prices.
      Hope this helps

    Hi

    Firstly great website.

    Can you recommend a supplier/installer in the Cheshire/ Lancashire area?
    Postcode L39

    Been advised of Altitude Aluminium, John Knight glass, Weru amongst others.

    All advice appreciated.

  35. Gev Lynott says

    Hi there
    We are trying to find a well regarded Aluminium Sliding Door installer in the Leeds/Wetherby area to install Reynaers CP130 LS or something equivalent- any recommendations greatfully received.

  36. Anthony says

    Sorry one more question please. What’s the difference between the Schuco ASS and ASE Sliding Door systems?

    Really confused between these.

    • Nick Dardalis says

      Hi Anthony, the ASS is the more widely used in a residential project. The ASE offers a different frame design, slightly less in the depth of the frame and looking at it seems slimmer and more suitable for new build openings. The ASE is more customisable as you can insert the entire frame within a facade system. Spec for Spec they’re fairly similar. The Schuco codes in their products usually relate to the performance and the size of the profiles.

      Hope this helps

    Dear Nick,
    This is such a great website, given most of us are spending a lot of money and doing this only once, we don’t have the experience in what to look for. I am having 2 sets of sliding doors in my new kitchen/diner – 3 panel slider and a 2 panel slider at right angles.

    Wanting all panels to move, and thin frames I have narrowed the choice to two 1) Sunvista by Compassglass and 2) Seiger slim by Hedgehog/IQ. The costs are quite different (Seiger over £6k cheaper) and having done a comparison I can not see any real difference between the two products…am I missing anything?

    Also Sunvista have PAS 24 security rating and Seiger does not – is this a problem?

    Sunvista have a 10 year warranty, but Seiger only 5, this makes me think they don’t have confidence in their system, does the warranty duration matter?

    Finally how can I be sure that both systems are truly weather tight as I’d like the track flush with the floor. The sales teams say they are, but how do I check?

    Any advise welcome.

    • Nick Dardalis says

      Hi Rowena, thanks for your question and your kind comments on our website.
      First of all, every supplier should be able to back up their weather performance and security claims with independent certification such as SBD, UCAS, Wintech Engineering and other testing houses.

      Now being fair to the product, if they don’t have independent certification this does not mean their doors are easy to break into or will leak. It simply means they have not been submitted for independent tests. Many products are re-branded under different names and ride on the back of the original certification – this is fine too. Modern doors today are designed to be weather tight but a top-notch installation is key as is working with your builder to ensure a suitable method of drainage if needed on the outside. No door is water proof and 100 sealed. They are designed to resist the weather but any water that does get into the threshold is designed to drain away to the outside.

      The warranty is down to the individual supplier. Most glass units only come with a five year warranty from the manufacturer. Therefore, many suppliers think well the glass fails before any of the aluminium in years to come so no point in having a long guarantee that they will foot the bill for when they only get five years from their glass or other suppliers. It is an individual business decision.

      There is very little in the products you have seen so go with one at the aesthetics you like and the right price. Confidence in who you’re buying it from is also important. If you are looking at these two, I’d like to suggest you look at the Sunflex SVG 30 system as well. One advantage of this is it is just as narrow as the others at 30mm but without the thick deep profile typical of these doors. Worth a look and an excellent sliding door

      Hope this helps
      Kind regards
      Nick

  38. Anthony says

    Hi Nick. What a great website for a novice consumer trying to understand the different systems out there.

    We are looking for sliding doors 6500 x 2600 or 6500×2800.

    I have come across the Cortizo Vision or the Cortizo Vision Plus. We love the slim profile look of these. Any thought on these?

    Is there any other slim profile systems that you would recommend over the Cortizo?

    Many thanks in advance.

    • Nick Dardalis says

      Hi Anthony, thanks for your enquiry and your kind comments on the website. The Cortizo sliding doors are widely used in the UK under either the Cortizo name or other brand names where companies use exactly the same product but brand it differently. It is a Spanish system with an excellent reputation in Europe and in recent years has gained particular prominence in the UK.

      The main differences between the Vision and the Vision plus is sight lines. The Vision has a sight line of 20mm at the door interlock, with the Vision Plus 25mm. The Vision Plus goes a bit wider per panel at 2500mm vs 2200mm for the Vision but both will go up to 3metres high. The other significant difference is the frame depth with the Plus being 180mm deep vs the Vision at 116mm. These differences are down to the strength/structural integrity of the system, but otherwise very similar specifications. The doors are made the same, using the structural silicone glazed system. The Plus is simply designed to take bigger weights, the option of automatic operation and is the more robust of the two doors.

      At the sizes you have, any of these doors should be suitable. The only thing to ensure is your supplier has experience with these doors.
      There are other slimline systems such as the Reynaers Hi Finity or Ultraline doors. Reynaers is also excellent. Also there are other doors such as Infiniglide doors, Air SL20, Origin and Others, also based on the Cortizo system but modified in the way they’re supplied or provided.

      This is the more expensive of the patio door products owing to their construction. You could consider the Visoglide Sliding door, cheaper with just a 35mm mullion. To be honest the difference in the sight lines is marginal given the big width of your doors. Don’t forget also, that while these very slim doors are thin to look at on the face, they will be much deeper as you look at the doors from the side.

      Otherwise all doors meet great specification and correctly made and installed will give you years of reliable service. The only thing to be aware of is some of these doors are not supplied with the provision for a trickle vent in the head and these are required in new build openings as part of the Building Regulations unless you’re providing ventilation elsewhere in the room.

      If you would like prices from anyone on any of these and other products, drop us a line via the contact form and happy to put you in touch with some installers if you can give me your location.

      Hope this helps, please don’t hesitate to get in touch if you’ve any questions or need further information. 
      Kind regards
      Nick 

      • Anthony says

        Thank you Nick. That’s a great help.

        I’ll look at the alternatives such as the AL20 and Visoglide.

        Regarding supplier, I’ve spoken to a company called Polish Interiors for the Cortizo System. They have Sales Offices (for Fensa and warranties) in the UK but manufacturing is in Poland. Any thing I should be concerned about here?

        If you have any suppliers you can recommend around the Wembley/Harrow area, please send me the details.

        • Nick Dardalis says

          Hi Anthony, our answer to doors made in Europe is always the same. There is nothing wrong with buying your doors from a factory abroad as long as you are covered on a number of areas we consider important for your peace of mind.

          1. Ensure that the door comes made for UK standards. So if in the UK the system is marketed as meeting PAS24 or SBD or particular weather performance standards, that you are getting THAT product. For example a tested/certified door has achieved its certification with a particular lock and configuration/specification that might differ with a European made door even if it’s the same system.

          2. Ensure that you can get good service levels if things go wrong. By things going wrong, this does not mean a nightmare installation but things that can go wrong in the course of an installation. For example the door cill gets scratched and needs replacing or another section needs changing. Will you be waiting weeks for those small things off the shelf/available quickly here because they have to come from Poland?

          3. Ensure that post-installation your chosen company offers support for the product. If the factory changes procedures/components in Poland will you be able to service/repair your door in the event that it needs it?

          Apologies if I seem to highlight the negatives, but in our experience, these are typically the things that can make the attractive price of a European sourced door seem less attractive if even simple things need sorting out.

          Hope this helps,
          Kind regards
          Nick 

          • Anthony says

            Thanks for the honest feedback Nick.

            I think I should weigh up the savings with suppliers in the UK.

            I’ll drop you a note if you can recommend anyone to me.

            Many thanks.

  39. Lisa says

    Hi, we are looking for sliding doors 5.4 x 2.1 and have been given a few decent quotes, one being for Aluk from Alpine Aluminum, and another for edge glide from Bifold Direct. Alpine have awful reviews which has put me off but I can’t see much about Edgeglide doors online, could you give me your opinion please? Unfortunately our budget is very tight as we are doing a complete renovation so this makes the likes of origin and Schuco out of range for us.

    Thanks in advance for your help.

    • Nick Dardalis says

      Hi Lisa, thanks for your question. The Edgeglide is a very good system although there are slimmer doors out there. Edgeglide has a 42mm interlock, the Smart Systems Visglide has a 35mm mullion so a little thinner on the sight line.

      Very good product with Edgeglide and it’s arguably better engineered than the AluK although this is a good door too.

    Hi Nick

    We are building an extension and looking to purchase doors for an opening 3.6 x 2.2. We have got the options down to Air600LS or Architectural Vision Systems. The AVS are slimmer but there seems to be very little written on them, are they making their own doors? I’ve read loads on Air and all seems positive but these are thicker framed. Can you please give me your opinion on these especially AVS.

    Many thanks
    Jack

    • Nick Dardalis says

      Hello Jacky, thanks for your question.

      The AVS doors are marketed as frameless and they are not. They are a structurally glazed aluminium sliding door, which we explain on the website has the glass providing the structural integrity over the aluminium. If you want a more frameless system take a look at doors by http://www.fgc.co.uk.

      I’m not sure which system AVS use or whether it is their own system, but it appears very similar to the Cortizo system that many use for their slimline, structurally glazed doors. https://www.aluminiumtradesupply.co.uk/23546/who-makes-the-slimmest-sliding-doors/

      Are you aware that air doors also come in a similar type of door to the AVS with their air20SL product? You can see this at the Everglade Showroom in Middlesex

      Everglade Windows in Perivale Middlesex
      http://www.everglade.co.uk 
      020 8003 1309
      Wadsworth Road, 
      Perivale, Greenford, 
      Middlesex, 
      UB6 7JD

      The air 600 you are looking at is not the same door as the AVS so you’re not really comparing like for like and I would suspect the 600 come out cheaper as well. Our view is that the mullion sight lines on these doors are down to personal opinion as to their aesthetics. While the AVS and other doors are much slimmer with the 20mm mullion, the depth of the profile is substantially deeper than the 600 and other conventional non-structually glazed doors. So when you look at the AVS style doors from the side you see much more aluminium than the other door.

      Ultimately it is down to which door you like the look of, at the price that is right for you, and of course, confidence in the company you’re dealing with.

      If you’re still undecided and would like to see some other brands to compare, get in touch via our contact form with your location.

      Hope this helps, please don’t hesitate to get in touch if you’ve any questions or need further information. 
      Kind regards

  42. Paul. F says

    Hi Nick,

    Please can you help us?

    We are in the market for some aluminium doors and like the Dutemann Glide-s 94m. In order to match we are trying to find an alternative just so we can get a quote but are finding it hard. Would it please be possible to recommend some? The only one we have found is Schuco but cannot not find any reviews vs. Dutemann. Plus his are they going to match vs. Price?

    Thanks a lot

    • Nick Dardalis says

      Hi Paul, the Dutemann Glide-S is an excellent sliding door and well worth considering. Dutemann in Dartford making this is also an excellent manufacturer. The Schuco is a good contender and nothing really to separate the two. The one good thing about the Dutemann is it’s extra-width capability giving you over 6 metres in just two panels.

      Another to consider is the air 500/600 range of doors also very good indeed and comparable with Dutemann. I think you’ll be happy with either but the Dutemann is just that little bit more exclusive. If you like it, go for it.

  43. Ailsa Abbot says

    Hi Nick
    So pleased to have found your website! We are in the middle of a kitchen extension. Originally the architects were recommending Schuco ASS70.hi sliding doors, but have now told us this is a no-go because the doors make up two walls of a square room and where they meet in the corner, we have no post/beam. Schuco require a beam/post.
    They have recommended instead to go with Alumil S560 which they have said will be around the same price.
    I wondered if you thought they were of the same quality / reliability / aftercare customer service? Do you think the Alumil is a fair comparison with the Schuco? Also if it’s true they are around the same price?
    Thank you so much
    Ailsa

  44. Luis says

    Hi Nick,

    We are currently in the process of choosing doors for our new extension. We have two openings which meet at a corner post measuring 4.1m (onto a 600mm wide walkway followed by our lawn) and a 4.8m opening onto our patio area. We are considering a 4 pane bifold onto the patio and a 2 pane twin track lift and slide onto the lawn.

    We have looked at many systems in person and have many varying quotes. At present our preferred option is looking like the Schuco ASS70HI and Schuco ASS70FD systems. Do you have any knowledge of these systems and are they a good choice? Will these sliding doors and bifolds look ok when paired together? Is there any drawback to having both panes on the slider as movable? Do you have any advice regarding the corner post where these systems will meet as we would like these to meet at an exposed corner post rather than cladding the post and making it wider than it has to be structurally.

    We are looking at having a level threshold and Schuco order various options, do you know which is the best for a weather ratings whilst still being seamless?

    Thanks in advance,

    Luis

    • Nick Dardalis says

      Hi Luis,
      An excellent choice of door with Schuco – arguably one of the best brands out there. However, there are other great sliding doors such as those from Reynaers, Air Doors, Sunflex and others.

      Usually the profiles on sliding and lift and slide doors are the same or virtually identical so I don’t think you will get any substantial visual differences.

      Bifolding doors will look different as the profiles are for folding doors and of course, the sight lines are not the same (thicker) when bifolding doors are closed.

      I think you’re choosing well with both types of doors as you get more flexibility and the bigger glass panels on the sliding version. Also no drawback with having both panes movable – I think you get a far more flexible door that way.

      Can’t see any obvious drawback to both doors meeting at the corner post but sounds like your corner post is a fixed one?

      Cladding the corner post need not thicken up the sight lines. A competent contractor can easily obtain a 1mm thick aluminium pressing to cover the steel/concrete post in the same colour as the bifolding and sliding doors. This is frequently done.

      If you’d like to get in touch with the website (assuming you’ve not yet appointed a contractor) with your location, happy to try put you in touch with someone that can help.

      Hope this helps, please don’t hesitate to get in touch if you’ve any questions or need further information.

    Hi Lois, it’s obvious looking at the picture of this that the outer frame is heavily enhanced to take the substantial weight this foldback arrangement creates where the doors all hinge back together.

    I’ve never seen this in the UK, nor do i know of a comparable. Every market has a different requirement, such as Europe preferring opening in windows to our opening out. As far as I’m aware there is no similar product in the uk.

  46. Lois says

    Hello – I love the idea of bifold doors that get completely out of the way by folding flat against the exterior wall rather then than sticking out at 90 degrees. The only product i’ve found so far is made in New Zealand. do you know of any uk company that makes/supplies a similar product. I’m surprised at the difficulty i’m having especially as internal wall flush bifolds are available.. This is the product by Altus Windows in NZ.

    Hi Nick
    Thank you for the kind response. I found your your response very informative and helpful. Can I please ask if you can advise us here about your view on ID System sliding door.

    I have found the ID system – theEDGE2.0 very good looking and very much equal to the Panoramah! and IQGlass and was wondering if this is developed by ID System in house.

    I also found on your website a number of different manufacture who does do very slim sliding door like below:

    Sunvista Sliding door 19mm
    Air 20 SL Sliding Door 20mm
    Fenster Fabrications Uni-Slide Door 20mm
    Origin Sliding Door 20mm
    Greenways Architectural Ultraline Sliding Door 20mm

    Any recommendation on these systems or anyone I should be aware of.

    Thank you
    Essa

    • Nick Dardalis says

      HI Essa, all of the current slimline sliding door systems have good security, weather performance and are very similar in their aesthetics and specifications. You won’t get a bad door with any of the products you mention.

      Go with the door you like the look of, at the price that you like and of course, confidence in the company you’re dealing with.

      All these doors, correctly made and installed will be reliable in the long term.

      Some of the names you mention are based on the Cortizo system, others are designed in-house. It’s hard to know exactly what manufacturers do with their doors. Some will take the Cortizo and customise it quite heavity to make it unique to them, others use a standard product. Whatever they do does not compromise the product in any way.

      All these doors also come from very good businesses so sure you’ll be happy with any of these when made and installed correctly.

      Hope this helps, please don’t hesitate to get in touch if you’ve any questions or need further information.

    Hi Nick

    We have had a set of lift and slide doors fitted 6 months ago and after multiple repairs they have water leakage, air leakage and one of the doors no longer opens fully.

    The manufacturer was Exlebesa and fabricator was Alufas – do you have any experience of either company?

    • Nick Dardalis says

      Hello Dawn, thanks for your comment and sorry you’re having trouble with your doors. The Exlabesa product is widely used commercially and in dwellings and we’ve never had bad reports of it. It does very much sound like manufacturing and/or installation issues. It is hard to comment on whether the leakage is through the door set itself (manufacturing) or where the frame meets the structure (installation).

      I presume you are in contact with the installer and they are attempting to correct the faults? Another option is to contact the systems company Exlabesa and see if they’re willing to carry out a site inspection with Alufast to establish the cause of the problem. It is in their interests to ensure their products are being made and installed in accordance with their technical manuals.

    Hi,
    I am doing a full house remodelling and also moving my kitchen from one end of the house to another. I found your website very informative and some very good comments and questions asked. I noticed that two of the manufacture I was looking at was on this website:

    Panoramah! Sliding Doors.
    IQ Glass Minimal Windows System

    Now some facts about my requirement. Living in the UK Bi-folding doors does not make much of sense to me, most of the time the door are closed and so all i get is interrupted view to the garden. So based on this I decided to go for 3 x Panel Sliding door. Reason being is that i can have 2/3 of the space open at any time.

    Technical Data.
    3.6 Meter Width x 2.1 meter Hight.

    The quote from IQ Glass and Panoramah! is very close so I had a few questions.

    A) In the article you kindly point out about mullion and interlock (not sure I understand) so what is better looking if I want as thin frame as possible? Do I go for 20mm or 30mm

    B) some customer of sliding door talk about a step / cleaning. The step is there to keep the water out and the cleaning is that it gets dirty in the track? Is this something of a concern and what are the key questions to ask?

    C) I am wondering if for the space it is better with two vs three panel? Can you provide you own opinion on this matter?

    D) Comparing the two I have big concern for Condensation, has this been resolved in the latest doors? Is there a way to check this ?

    E) Which one has more condensation and UV resistance ? Panoramah! Sliding Doors or
    IQ Glass Minimal Windows System.

    Once again thank you for a great website.

    Kind regards
    Essa

    • Nick Dardalis says

      Hi Essa, thanks for your questions and kind comments on our website.
      Both Panoramah and IQ Glass are excellent companies, renowned for their high-end work and top class products. I will try to answer your questions as best I can.

      A) In the article you kindly point out about mullion and interlock (not sure I understand) so what is better looking if I want as thin frame as possible? Do I go for 20mm or 30mm

      The interlock refers to the vertical mullion on a sliding door. There is one mullion on a two panel door, two on a three panel. The 20mm interlock probably relates to the sliding door system made around the glass which is typically the minimal-framed sliding door. The 30mm interlock indicates the slightly thicker sight line and the less complex product. Obviously I’m not aware of what system you’ve been quoted for. Whether you go for 20mm or 30mm is really down to you and the overall aesthetics of the door. The difference is so small I don’t think it will make a difference, so go with the door you like the look of the most and the one that slides the best for you.

      B) some customer of sliding door talk about a step / cleaning. The step is there to keep the water out and the cleaning is that it gets dirty in the track? Is this something of a concern and what are the key questions to ask?

      Every sliding door needs weather protection at the threshold. I don’t know if your door is intended for a new extension or to replace an old set of doors. Your installer will in most cases work with your builder or you to establish how high you want the threshold so it creates a minimal step-over as you go through the doors. Some people leave the doors as they are, others set them lower to give less of a step and sight line at the bottom. Either way the doors need the track to prevent water ingress and ensure any water that does get on the threshold drains away to the outside. Cleaning you will have to do routinely as dirt does get into the track and you need to keep the track clean to keep the rollers free of obstruction as you move the doors.

      C) I am wondering if for the space it is better with two vs three panel? Can you provide your own opinion on this matter?

      Go with what you like the look of the most. The width of the doors sometimes affects the choice of two or three panels and some great doors achieve enormous widths with just two panes where many need three. The less panels the more glass area and better visuals. However there are other considerations such as handling big panes of glass, accessibility round the back of your house to fix the doors, cost and other factors. Talk to your installer and work with them to decide on the best option for you. There is no better or worse option – it’s what you would like. However a two panel door will look more minimal than a three panel.

      D) Comparing the two I have big concern for Condensation, has this been resolved in the latest doors? Is there a way to check this ?

      No. There is terrible advice and information around about condensation. You must be aware no new windows and doors will never eliminate it altogether as there are so many factors that cause it. How we live in our homes, the level of moisture, the amount of ventilation, heating, cooking, living all affect moisture levels and condensation. Modern windows and doors all have thermally insulated frame and very energy efficient glass that works together to create an insulated product. They may help reduce condensation but do not expect never to get any. This leaflet from the Glass and Glazing Federation provides some good advice on condensation. http://www.ggf.org.uk/publication/condensation_some_causes_some_advice Obviously modern windows are better insulated than old windows but no window will give you a condensation-free house.

      Finally, expect to see condensation on the outside of your glass during autumn and winter – this is normal with modern insulated glass and nothing to be concerned about. It is the glass doing its job!

      E) Which one has more condensation and UV resistance ? Panoramah! Sliding Doors or
      IQ Glass Minimal Windows System.

      Condensation I hope I’ve answered above for you. UV resistance is down to the glass you choose to have in your doors. Speak to your installers and they will be able to provide you with the technical data on this. Hard to answer without knowing what glass you intend to have in your doors.

      Hope this helps, please don’t hesitate to get in touch if you’ve any questions or need further information.

    Hi Nick,

    Your website is exactly what I needed to see right now. We are looking for sliding doors 3000 x 2070, and we really need a good system, that is child friendly with fairly narrow sight lines at a reasonable price, we are having the kitchen done and are on a tight budget as the price of the kitchen is a lot higher than anticipated. Please can you recommend some installers that would be able to help us, we are based in South West London.

    Many Thanks

    • Nick Dardalis says

      Hi Sadia, thanks for your question and your kind comments on our website. There are many installers serving your area with a broad range of sliding doors. There is no ‘bad’ product on the market so you can expect a sliding door with a good specification and certified security and weather performance with most doors on the market. Good manufacturing and a professional installation is key to a reliable product.

      Aluk sliding doors and Smart Systems Visoglide doors are great and at a good price point. Reynaers doors, Air sliding doors and so on are excellent as are Schuco. These brands have pretty good slim sight lines as well.

      You mention child-friendly and there is a new Warmcore door on the market that has a very good feature for a family home. The Warmcore inline sliding door has Safety Brake. Safety Brake is an option that prevents the doors from being slammed shut. It also works as an anti-finger trap device. This will appeal hugely to families choosing bifolding doors on the back of their finger safe gaskets. The safety brake slows down the door to a soft final close, dampening the closing force significantly. The door offers this safety feature on either the lock side or opening side as well as both sides. Worth checking out and there is a review going live on this product in the next couple of days. It’s not the slimmest door on the market, but Warmcore has excellent U-Values and we really like this safety-brake/soft close feature.

    Hi Nick,

    I am in the market for a bifold door. I have been advised about Grabex. What is your view on them

    • Nick Dardalis says

      Hi Rajiv, thanks for your question.
      The aluminium bifold from Grabex is the Reynaers CF77 system which is a very good bifold from a strong brand. Grabex does a lot of good work and if you’re happy with the price, the product and of course, confidence in the company you’re dealing with you, you should enjoy your bifold door for years to come.

    Hi

    Your website has been very helpful – so many systems and not many places to compare them!

    I am looking to put in Lift and slide patio doors – 2.1M x 6M (split over 3 panels on triple track). I am looking for the narrowest sightlines – can you advise which brand wins !! We would look at options if there are big price differences.

    Many thanks,

    Craig

    • Nick Dardalis says

      Hello Craig, thank you for your kind comments on our website.
      There are a number of doors to choose from with lift and slide doors such as Smart Systems Visoglide, Reynaers, Air, Dutemann AluK sliding doors.
      Take a look at this article we put together on virtually the sliding door brands in the UK ranked by sight line. https://www.aluminiumtradesupply.co.uk/23546/who-makes-the-slimmest-sliding-doors/

      Any doors that are below 35mm are the slimline sliding doors and these are not available as lift and slide.
      Hope this helps, and do get in touch via our contact form if you’ve any questions.

      Kind regards
      Nick

  54. Mark says

    Hi,

    What are your opinions on the Dutteman Glide S versus ALUK BSC94 45mm? We have not managed to see the ALUK but several local dealers are pushing them as excellent products. Are either product considered more premium than the other? Price wise, there is not too much between them.

    One preference is ease of use, hoping that young children will be able to slide them themselves so they can let themselves in and out of the garden.

    thanks

    Mark

    • Nick Dardalis says

      Hello Mark, thanks for your comment. Have replied to you by email on this. For brand perception, I would say Dutemann. That said, AluK doors are very good, excellent sellers and AluK are one of the biggest and best-known aluminium systems companies in the UK. The Dutemann door is available based on the Schuco system or the new FD85 that you can read all about here. https://www.aluminiumtradesupply.co.uk/23551/dutemann-fd85-bifolding-door/

  55. Tracy says

    Thanks very much for your reply .

    Could you advise a reputable company in the Glasgow you would recommend for sliding doors ?

    We are getting reading so many reviews , good bad for company’s and we are really struggling to commit.

    Thanks

    Hi

    Really happy to have came across your website as it seems so helpful.

    We are in the process of building an extension and are looking to purchase sliding doors .we have a width of 4.8m by 2.1 m height.

    We have received a price for the smart visoglide plus lift and slide and also Reynaers XP glide r system .

    The xp glide r is quite a bit more expensive but upon looking at both I felt the xp glide r had a better finish .

    I would really appreciate your thought s on both and if it is worth paying the extra .

    Thanks Tracy

    • Nick Dardalis says

      Hello Tracey, thank you for your question and your kind comments on our website.
      Yes it is. There is nothing wrong at all with the Smart Visoglide sliding door. It is widely used, very reliable and well priced. However, the brand perception of Reynaers is a lot higher and the engineering behind the product just that little bit better. If you felt this when seeing the door then you can see it’s arguably the better door.

      The most important thing with any door is good manufacturing and good installation. There is no bad door or window on the market and you’ll be happy with either.

      Hope this helps, please don’t hesitate to get in touch if you’ve any questions or need further information. 
      Kind regards
      Nick 

      • Marti n Burnett says

        The above statement is totally correct .The glass on the Reynaers is brought forward that creates a better all line smother front looking finish .

  57. Anne Conlon says

    Hi,
    Delighted to come across your informative website. Thank-you.

    We are in the process of buying 4 pairs of double glazed aluminium sliding doors, each door 2750mm high x 4500mm wide (i.e. each sliding half 2250mm wide). 2 of the sliders will meet in an open corner.

    We are looking at Reynears CP155 and Sapa Confort 125 (lift & slide) and wondered if you could advise us from your vast experience:

    1. Which of the above systems is superior in meeting our specifications?

    2. Whether because of our 2750mm heights we should be looking at higher spec systems?

    3. Is there a system on the market that meets in an open corner where the other doors in each pair can also slide (i.e. doors can slide open from both directions and middle ones meet in an open corner)

    Would love to hear from you soon as we need to make a decision soon!!!

    Best regards,
    Anne

    • Nick Dardalis says

      Hello Anne, thank you for your kind comments on our website.
      The products you’ve looked at are excellent. There is no bad door or window on the market but where they differ is who makes them, the overall supply chain and the quality of the installation. All the current systems will meet or exceed industry standards for weather performance and security, as well as the quality of aluminium and the paint finish. Where they can also differ is in their aesthetics, overall sight lines, engineering, the quality of the hardware/components, the choices available and their brand perception.

      Any correctly made and installed door should give you reliable service long term. The Reynaers door is arguably better known than the SAPA product in the residential market, that said, SAPA is routinely specified in new build developments of dwellings.
      Also worth looking at air doors and Schuco doors.

      If you can get in touch via the contact form on the website, I can put you in touch with some local installers.

      Hope this helps, please don’t hesitate to get in touch if you’ve any questions or need further information.

  58. Rhona MacLeod says

    Hi,

    Im looking for patio sliding doors. Our local supplier stocks Dutemann Glide- S Sliding door and Reynaers CP30 lift and glide. Would you recommend one over the other?

    many thanks

    • Nick Dardalis says

      Hi Rhona, you’ve seen two very good sliding doors on the market and either will be good in your home. Our advice is to go with the one you like the look of, the price you’re happy with and, of course, confidence in the company you’re dealing with. While Reynaers is a very long established brand compared to Dutemann, arguably the Dutemann is in the UK, that little bit more exclusive.

      Hope this helps, please don’t hesitate to get in touch if you’ve any questions or need further information.

    Hi, I’m also in the market for a sliding patio door and have come across kleidco. I believe its manufactured in turkey. Do you have any insight on this manufacturer?

    • Nick Dardalis says

      Hello Saj, I am aware of this product and go for it if the price, aesthetics, function and the company providing it meets your needs. The only thing I would ask you to check with any internationally made product is how prompt the company will be with replacement parts in the event they’re required in the future and the general UK support for the product.
      Hope this helps, please don’t hesitate to get in touch if you’ve any questions or need further information.

    Hi, could anybody tell me what the costing will be roughly for 10 metres of slimline sliding doors in grey!

    • Nick Dardalis says

      Hi Jean, thank you for your comment on the Aluminium Trade Supply Website.
      It’s hard to give you a guide price as so many factors come into play such as size of glass, installation considerations on site, brand and so on.
      If you’d like to get in touch via the contact form on the website, we can put you in touch with a local installer that can give you a competitive quotation.

  61. Gab says

    Hi there, myself and my wife are in the market for some patio sliding doors and have got some quotes for a few different systems, all from companies we like and trust.

    Specification is all 6m span by 2100mm high (4 pane, center two panes sliding out onto fixed outer panes)
    – Quote 1 – Smart Visoglide £5778
    – Quote 2- Air 600 life and slide £7202
    – Quote 3 – ALUK £6110

    The difference in cost is not so significant, rather we would like to go with the better system. Is Air widely known as the better system than the other two in the above list, or is it marginal in your opinion?

    We will go see these installed soon, but really enjoyed reading your article and would really appreciate an opinion from you before we do.

    Many thanks

    • Nick Dardalis says

      Hello Gab. There is no bad door or window on the market. All the current systems should be designed to meet or exceed industry standards for weather performance and security, as well as the quality of aluminium and quality of paint finish. Where they can also differ is in their aesthetics, overall sightlines, engineering, the quality of the hardware/components, the choices available and their brand perception.

      Any correctly made and installed door should give you reliable service long term. The air sliding doors are excellent products with a long guarantee and an exclusive manufacturer also trading in the UK for over 30 years. The other brands are very successful in the UK and available from many different manufacturers. There are several differences between these three but you won’t get a bad product with either. However the air door many regard as having the better quality hardware and components, double the warranty and is based on a top brand aluminium system.

  62. Caroline says

    Hi Nick
    We are having a sliding door 5000m x 2100mm having researched further we have found lots of similar quotes now so we are happy we’ve found a good price with a local company. Do you know anything about Kaye building systems (KBS) ? This is the system they use.
    Thanks
    Caroline

    • Nick Dardalis says

      Hi Caroline, the KBS system is fine – widely used commercial in residential developments of flats and houses, although you won’t often see it in the typical local door and window showroom, it’s quite widely used commercially.

      If you have seen the product, are happy with the price and the company providing it, then you should be fine. A good reliable door is down to it being well made and importantly, correctly installed.

  63. Caroline says

    Hi do you have any info on a company called Slide and fold? They are very reasonably priced but almost seems too good to be true coming in at 3k less than express bi fold!

    • Nick Dardalis says

      Hi Caroline, every company has a different level of purchasing power, overheads and the profit they choose to put on the job. if you are happy with the product, the company behind it and of course the price then you should be fine. There is no ‘set’ retail prices for doors and windows given the complexity of the supply chain. It is quite a difference in price, but you don’t mention if this is just for one set of doors or if you are having other windows and doors fitted?
      Kind regards
      Nick

  64. paul doocey says

    Hi there is no mention of the visa glide plus system,I have received a quote form a company who use this product.They seem to be well known .would you recommend?

    • Nick Dardalis says

      Hi Paul. Smart Systems design the Visoglide Plus sliding door and it is a good door at a great price.

  65. Charlie Philips says

    Hello,
    Firstly I have found this website very helpful and informative so thank you!
    I’m in the process of buying some very large sliding doors and windows for a self build project. With 3 spans of over 5 meters and a total of 27 linear meters of glazing it’s a decision I’m conscious needs to be right!
    After getting many quotes I’m down to 2.
    The AP45s system from alpine aluminium
    The 7pi sliding doors and 5pi window system from Comar
    I have found some good reports on here regarding the Comar but can’t find any mention of the alpine system.
    In your informed opinion which would you choose?!
    The Comar quote is actually also around 4K cheaper……
    Any advice/information would be great.
    Thanks

    • Nick Dardalis says

      Hello Charlie, thank you for your comment on the Aluminium Trade Supply Website.

      The Comar system is extensively specified in commercial developments of apartments, flats and houses. So while you may not see it in the usual local window showroom it is a very dependable and reliable system which is one of many reasons why architects specify it. There are many homeowners in new builds and refurbished buildings with Comar doors and windows.

      The Comar 5p.i window again is extensively used all over the UK with very good security and thermal performance. If you like the look of the window and happy with the company providing it, you will be fine with this.

      There is no bad door and window system on the market but where they differ is who makes them and the overall supply chain. All the current systems meet industry standards for weather performance and security, as well as the quality of aluminium and quality of paint finish. Where they will differ is in their engineering, the quality of the hardware, the choices available and their brand perception. The Comar sliding door has obtained some excellent results in testing and any well-made and installed door will be reliable in the long term.

      The Alpine Aluminium product I am pretty certain is the AluK BSC94 sliding patio door. The images used in their brochure are all from AluK and all the profile dimensions and specifications are AluK as well from what I can see. The S denomination is the same patio door with the 45mm slimline mullion.

      The two products are different in their aesthetics but the Comar product is arguably the heavier duty product because of where it is used outside of normal residential installations. The sections are slightly beefier than the AluK door but both as I mention meet all the industry standards for quality of aluminium, the polyester powder coating, security and weather performance.

      I can’t comment on why the Comar system is coming out so much cheaper, but if it is, and knowing the two products well enough you opt for the cost saving. It is substantial for a very reliable, tried-and-tested door assuming you like the look of it compared to the AluK

    • Rachel Skelton says

      Hi Charlie, we are in a very similar position, looking for a triple track sliding door – did you go with either of these systems in the end and what are your thoughts a year or so later?
      Thanks

      • Nick Dardalis says

        Hi Rachel, there are some excellent sliding door systems on the market such as the air 500 and 600LS, Reynaers or Schuco sliding doors, SUNFLEX SVG30 and the latest slimline doors also available with a triple track.

        Any help much appreciated
        Kind regards
        Tim Freeman

        • Nick Dardalis says

          Hello Tim thanks for your question. Can suggest the following systems
          Cor-Vision based on the Cortizo system is very good indeed and widely used under various brand names. Aluk also has a very good sliding door at the moment in the infinium product as do Reynaers.

          Also worth looking at the Origin inline slider which is very well made with a good guarantee and from a very good business.

          If you want a door with a marginally thicker mullion (30mm) but still slim then the Sunflex SVG30 is a good one to consider.
          If you’d like to get in touch via the contact form on our website I can put you in touch with some local installers and have a look at some products.
