Updated on

The latest bifold door by Aluk, is an improved version of the existing Luminia F82 bifolding door, that’s now slimmer, neater, better engineered and ready to meet the new Part L Building Regulations coming in June 2022.

Aluk is a dominant and strong brand in the UK market with their products hugely popular with the trade and installer. The Aluk Luminia F82 Bifolding Door brings their existing folding sliding door offering up to date.

What is the Aluk Luminia F82 Bifolding Door?

AluK’s new Luminia F82 bifolding door follows the recent trend for slimmer, better looking and more feature-packed bifolding doors. The folding door market is very mature now, and until recently bifolding doors did not have much in the way of competition. By that, we mean homeowners desired a bifolding door and didn’t consider that today’s generation of sliding doors could offer a better product in the home as well. There are also far more bifolding doors available to homeowners, with at least forty names to choose from.

What AluK has done with their new bifold is concentrated on aesthetics, better-looking hardware and a focused effort to make this door appeal to those wanting a more premium product. We expect to see AluK busy working on increasing awareness of their products in the consumer market. Origin does this the best, closely followed by Reynaers.

Comparing the Aluk Luminia F82 with the Optio BSF70.

With the Aluk Optio BSF70 bifold door being a hugely successful product for Aluk, how does the new F82 compare? While the BSF70 is by no means dated, the F82 does offer benefits over the longer-established product. Therefore it makes sense to compare these two bifolds by the same systems company. Here is how they compare.

Where to buy the new AluK bifolding door.

AluK’s mainstream products, loved by builders and the broader trade market you will see promoted under the Optio brand name. There have been significant improvements to some of their systems, and some have stayed the same. The Luminia F82 bifold door falls under is premium product offering. As well as Luminia, you will see the Infinium range of products intended for the high-end market. Both Luminia and Infinium will be available via select AluK partners.

A partner or dealer network is a good thing when the brand is strong – again Origin being a great example. Where systems companies like Aluk could struggle is streamlining the dealer network to benefit the consumer.

The buying process for a door like an Origin product is simple and the brand message to the homeowner is clear. You go to an Origin dealer with prominent Origin branding in their showroom. They then buy the fabricated door from Origin. Origin is big on marketing, big on helping their dealers with their showrooms, big on training.

The AluK method of supply is different as AluK provides bar length and accessories to a nationwide network of fabricators. Even if these fabricators are specially selected (and AluK do have some very experienced manufacturers in their network), the homeowner arguably doesn’t have the clarity of who makes their door like they do with Origin, Sunflex, Sunfold, Air doors and others.

Features of the AluK Luminia F82 bifolding door.

The stand out feature of the new Luminia F82 bifold is how it looks. AluK has followed the trend of bringing out a slimline bifolding door with door mullion sight lines of just 122mm. Their existing BSF70 is 140mm. For those comparing bifolding door sight lines, this new bifold is up there with the Schuco ASS70 FD, the air 800LS, Reynaers CF77 and Senior’s Alifold doors. AluK has gone one better with the Luminia bifolding offering consistent sight lines around the door. Both frame and cill sightlines are of 97mm. It is a great feature, and it looks very nice indeed.

With the Luminia F82 bifold, you also get:

  • A more attractive slimline appearance than other doors.
  • Distinctive hardware, many unique to the product.
  • Great specifications.
  • Fewer aluminium components.
  • Low U-Values at just 1.3WmK depending on the glass specification.

AluK’s new bifold also has reliable, compact and slim stainless steel rollers giving a smooth feel as it slides and folds along its track. You get a choice of hardware and the flush pop out T-Handle, instantly identifying a door as an AluK, has been slimmed down, redesigned and looks very seamless in a slave door.

As with any well-designed bifold you can expect certain features as standard such as traffic doors, opening in or our, anti-finger trap gaskets and a low threshold option.

How good is the Aluk F82 bifold?

Any well-made and correctly installed door is going to be reliable. AluK does have much experience in designing doors and windows. This door is designed to be easy to make and easy to fit.

It is clear from seeing the door that the components are quite sophisticated. The shoot bolt mechanisms, hug the corner of the door leaf snugly. The hinges and rollers are attractive in themselves. AluK has designed this door well. In the square profiled version, the Luminia F82 is a handsome bifold door.

Aesthetics are essential to homeowners, and in many cases over and above security, weather tests and performance. Customers read the same messages across everyone’s doors today, so they expect them to be secure, have low U-Values and not leak. It is how they look that is important.

With the contemporary hardware, the flush nature of the handles, the pretty traffic door handle and greater symmetry than other doors, we think homeowners will like it. It is all about bifolding door aesthetics in today’s market. That said, it is also about the marketing and brand perception when Origin still has a mostly unchanged door for over ten years.

Options available with AluK’s Luminia F82 Bifold Door.

As well as the to be expected, excellent choice of colour and double or triple glazing, AluK’s new bifold offers the following options to homeowners.

  • Single and French doors using the same profiles.
  • The choice of square or chamfered frames and glazing beads.
  • Up to 44mm glazing thickness easily accommodating integral blinds and triple glass.
  • The option of internal or external glazing (good for commercial installations).
  • Anodised aluminium finishes. Available in a range of opening configurations
  • Door leaves up to 2500mm high but can go up to 3000mm subject to approval.
  • 1200mm door widths.
  • The option of a high insulation version of the product using thermal inserts.

What we think of the AluK Lumina F82 folding door.

We saw this door at the 2017 FiT Show, and it looked impressive. It is down to AluK to market the door to the end user, so they ask for it by name and encourage their huge fabricator base to make it. AluK designs some excellent systems but also has a ‘builders favourite’ perception to overcome.

Go to any bifolding door showroom with a range of doors on display and other brands are perceived and sold as more premium. Installers like the existing AluK Optio BSF70 bifold. It is reliable, widely available and well priced. However, many up-sell against it offering other brand names considered more premium. The Lumina F82 should help retain the customer to the AluK brand.

The reality is as well, that many installers buy-in and fit AluK windows and residential doors but offer an alternative brand of bifold. Hopefully, the new Luminia F82 is attractive enough to retain the customer to the AluK brand when looking for a complete installation of windows and bifolding doors.

The AluK F82 bifold is a great upgrade from the BSF70 model. You will find the sashes are slimmer, the doors go wider and taller as well.  Installers say it is easier to glaze compared to the BSF70.

AluK GB Ltd now operates from a new 350,000ft2 South Wales headquarters that is hugely impressive, demonstrating its strong position in the UK market. There has been a multi-million-pound investment in new premises, new production lines, a powder coating plant, R&D Facility and even a training academy. All this comes with a new product strategy for the trade and residential market, of which the Luminia F82 bifold plays a big part. See the product; it is a good bifolding door.

I contacted Nick @ ATS for guidance on what aluminium sliding door systems would be suitable for an opening in an extension that is going to be both wide and tall. He came back really quickly with very detailed and incredibly helpful advice. He is clearly extremely knowledgeable about the systems on the market and their respective features and capabilities. If you’re feeling a bit lost by the overwhelming range of choices out there, I’d definitely recommend contacting him.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did! I contacted ATS to request advice and Nick promptly replied with a wealth of information, providing us with options and relevant contact details. I only wish I'd found them sooner!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

It is rare that I write reviews, however after my very positive communication with Nick - enquiring about suitable slim sash aluminium windows for my project, I felt that a review was definitely warranted. I can reinforce the many positive reviews posted so far, Nick was very quick to respond, providing comprehensive detail, with excellent independent advice.In summary, great service, thank you Nick.

I dropped Nick at Aluminium Trade Supply an email re high security slim sightline bi-folds and their alternatives and he responded that quickly (and so comprehensively) that I felt bad I’d not paid him for his time!Nick Sir your product knowledge is outstanding and you are providing a level of service that goes wayyyy above and beyond expectations. I’ll definitely make sure I mention Aluminium Trade Supply to anyone I encounter looking for a fenestration solution 🙏🏼

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.

My experience with this firm was exceptionally good and this is notalways the case as a female, dipping a toe into technical waters.I was spoken too with courtesy and at a level that helped me consolidate what was needed .On top of that I was given a list of companies and places where I could obtain the type of product I needed.I could not thank them enough and would certainly go there again and reccommend others do too.
