Cortizo Sliding doors offer modern patio doors designed with the latest technology, engineering and slim sightlines. However, buying Cortizo products in the UK can confuse the homeowner as well as the installer. In this article, we provide information and a review about Cortizo as a system as well as their range of sliding doors.
Information about Cortizo Sliding Doors
Cortizo is a substantial systems company. The Cortizo name is very well known, especially in Europe and globally. The entire product range covers not just sliding doors. You will also find windows, residential doors, curtain walling and panel systems. Also available are balustrades and even PVCu products.
For sliding doors, there are 12 different models, although just two are widely available for homeowners and installers. These are the Cor-vision Sliding door and the Cor-Vision Plus sliding door.
Both the Cortizo Cor-Vision and Cor-Vision plus models use the structurally bonded method of upper-tier sliding doors. The bonded glass and the slim interlock are two features making Cortizo doors popular. Another is their contemporary look and the many ways to customise them.
Generally, these cutting-edge doors come only as an inline sliding door without a lift and slide option. You also get insulated aluminium profiles, a durable powder-coated finish and quality locking systems.
Where you can use Cor-Vision sliding doors
You will find these doors mainly marketed at the new extension market. However, we’ve seen many installations of these doors, replacing old patio doors.
As a result, these doors are ideal for both replacement and new projects. Their slim lines, low thresholds, square and modern appearance make these suitable if you want a minimalist and latest-generation product.
With two up to six panels, depending on the configuration, these fine European doors work well in both modern or traditional houses.
Understanding Cortizo sliding doors
Finding information about Cortizo doors is difficult when trying to obtain consistent information about the product. The reason for this is that many major manufacturers use the Cortizo system but rebrand it. The number of suppliers selling this brand under a different name appears to outnumber those selling as Cortizo doors.
Therefore, we provide a list of just a few companies using the Cortizo sliding door but rebranded.
- Origin Global with their OS-20 Artisan Sliding Door.
- Everglade Windows selling the Air 20 SL product.
- Arkay Windows using the Infiniglide name.
- Architectural Vision Systems using several Cortizo products.
- Slimline Aluminium under the SL20 Classic range.
- Perfect Crystal using the PC20
- Home Hub Group using the Serenity brand name
The very important thing to consider is there is nothing wrong with buying a rebranded Cortizo slider. Origin, Everglade and Arkay Windows are just three of many outstanding manufacturers offering expertly-crafted sliding doors. They offer a different set of personalisation options, perhaps enhanced locks and handles. We also know companies such as Architectural Vision Systems offering an excellent steel-look version of the Cortizo door.
Skyglaze in Surrey was the first company to introduce Cortizo Cor-Vision doors to the UK. They’ve also done substantial and noteworthy work helping Cortizo develop the product better.
Therefore, and as with any substantial investment in glazing, do your research or contact us for help and advice. What you will get with Cortizo Sliding Doors are exceptional sliders and a contemporary, highly-engineered product. The slim lines, quality glass and excellent components create a door of excellent proportions with smooth slide action.
Finally, the 20mm interlock and slimline sliding doors remain heavily marketed. Remember it’s only two or three panel doors truly benefitting from a slim mullion. Four panel doors meeting in the middle always look thicker.
Cor-Vision Sliding Doors.
The Cor-Vision product is more popular. First of all, is the slimline 20mm mullion – arguably its best feature. Available from one up to six sashes and with single, double or triple tracks, the Cor-Vision provides a slimline sliding door for most residential projects. There is also an open corner version. Also, with the design, it’s possible to fix these doors giving a near frameless appearance. For new extensions, these doors can also slide into a wall pocket, disappearing when fully opened.
For door sizes, these doors go up to around 2.5m wide and up to 3m high. While these are the stated figures, some manufacturers offer these or reduced sizes. The reasons for this vary but mainly down to handling, transport or cost. Generally, this model goes up to 320kg, enough for most patio door sizes.
You will find this door typically double glazed with laminated or toughened safety glass. With glass thicknesses up to 30mm, these doors only come double glazed. Triple glazed requirements mean moving to the Plus model.
With most models of the Cor-Vision, you get a five-point lock integrated within a recessed handle. All doors come tested and designed by Cortizo for the suitable air, wind and water weather ratings.
The Cor-Vision Plus sliding door
The Plus version is broadly the same but differs in several areas. First of all, is the mullion. At 25mm it’s slightly thicker but a small difference bearing in mind the large sizes used for most patio doors. The profile thickness of the doors is greater too, for structural integrity as this door comes capable of much bigger sizes.
Then you get the glass up to 54mm thick, meaning triple glazing options when needed.
It comes with the same number of panel options. Tracks are limited to one or three. This means you get the option of a single slider and fixed pane, three and four panel options. You also get the same five-point lock. This model also offers an automatic sliding action when used with suitable automatic door gearing. This version is really only suitable for new extensions. The automatic gearing needs concealing in the structure above with most automatic versions.
Technically, the Cor-Vision Plus goes wider and taller and with greater weight capability. Individual sliding panels go up to 4m wide and 4m tall with a maximum weight of up to 400kg.
Security on Cortizo products
This is where you need to do your research carefully. The Cortizo website doesn’t mention any specific security tests for this door. Now, this does not mean your new Cortizo product is easy to break into. And we’ve never heard of anyone doing so up to now.
We’ve also done a search on the Secured by Design Website and there’s no mention of the manufacturers we know having an SBD license for the product. Our advice to you is to speak to whoever is quoting you. Ask specifically about their product rather than the Cortizo system generally.
Most of the suppliers we’ve checked out offer their doors with the standard Cortizo lock enhanced with a high security cylinder.
Colour Options with Cortizo
Once again, we stress that every Cortizo sliding door supplier probably offers different colour and personalisation options. For instance, Origin only offers the same colour inside and out. Other suppliers may offer dual colours, anodised and even wood-effect finishes.
However, every door should come with a certified and guaranteed powder coated finish, applied to the relevant industry standards.
Buying Cortizo sliding doors.
You will find Cortizo sliding doors available through many different professional suppliers and installers. To help you buy these doors correctly, we must again stress that you won’t find a ‘standard specification’ product – as so many versions and brand names of this door exist. However, we list below some things to consider and questions to ask of your Cortizo sliding doors provider.
Check what locking systems, door cylinders and handles come with your doors.
Cills and accessories, as well as ancillary profiles, may vary from supplier to supplier.
For new build extensions and renovations, establish whether a trickle vent is available – not every door comes with this option.
Remember the full choice of colour options won’t be available with every product.
There is nothing wrong with buying a door under a different name. Most professional suppliers will happily declare it’s a Cortizo System.
Guarantees on these doors vary from supplier to supplier.
The low or flush threshold comes with these doors but check with the supplier for drainage of water.
We love these products and suggest you consider them alongside other modern patio doors. However, just like all structurally bonded doors, they differ from conventional sliders where the glass goes in the door at the property. These doors must be factory glazed as part of their production process.
Well made and correctly installed, you’ll benefit from minimal aluminium profiles, expansive glass panels, lots of natural light and a great new living or kitchen space.
