Cortizo 20mm Slim Sliding Doors

Cortizo Slim Sliding Doors are the ultimate in luxury Sliding Doors. What makes the Cortizo Sliding Doors so fantastic is that the glass is structurally bonded to the aluminium frame. This makes the frame incredibly strong and secure so that a minimal, slimline aluminium interlock with sightlines of just 20mm can be achieved.

Depending on the overall weight, each Sliding Door sash can be made up to 2.5 metres wide and up to 3 metres high, perfect for homes with a tall ceiling to make the most of the view outside. 

The Cor Vision Sliding Doors are perfect for either a refurbishment or a new build.  Depending on the space you have available you can choose to have either 1, 2, 3, 4 or 6 sashes in your home.

If you are looking for an Inline Sliding Door system which will wrap around two sides of your home, the Cortizo Cor Vision Sliding Door is ideal. The doors can be made with a 90° corner without a mullion, so you can enjoy uninterrupted views of your garden and beyond with an open corner solution. 

If the Sliding Doors are being fitted into a new build property or a refurbishment, you could incorporate the Cortizo system as a pocket door. With a pocket door, when the doors slide open, they seem to disappear into a purpose-built wall, so that you can benefit from a wider open space. The glass in our Sliding Patio Doors is double glazed, with either toughened or laminated safety glazing. Both of which offer excellent acoustic insulation up to 41 decibels, so that you can enjoy playing music inside your home without upsetting your neighbours and equally, once your doors are closed, any external noise outside of your property will be kept to a minimum. Cortizo Cor Vision Sliding Doors are thermally efficient and achieve a U Value of 1.3 W/m²K to keep your home warm. With such a slim 20mm aluminium sightline, the doors appear almost frameless, however, there is a wide choice of powder coated RAL colours to choose from for the aluminium framing, with the option of dual colours, with a different colour frame inside and outside your property.

Recessed door handles are fitted to the inside of the sliding doors only, which results in both a contemporary, sleek aesthetic externally and makes the doors incredibly secure, as the handle cannot be tampered with from outside by an opportunistic burglar. Internal handles are available in a choice of five colour finishes; Hipca White Gloss, Slate Grey Matt, Anthracite Grey Matt, Jet Black Matt and a Light Silver and will perfectly complement your aluminium frame should you choose one of these colours.

From the first moment when Arthur came round to advise, measure-up and quote for the job we felt we were in good hands. And his team of installers provided the best service. I always think that the best test is if something needs further attention and in this case they returned promptly to fix a small issue and nothing was too much trouble. Our new doors have transformed the back of our house and we highly recommend this company for work of the highest quality. Thank you Arthur and team!

We got our back and front doors replaced by E&A Windows and we couldn't be happier with the job they did. Erez was so helpful as took the time to come to our home to give us a quote, explaining all our options thoroughly and clearly without being pressuring in the slightest. The quality of both doors was fantastic and Adrian’s installation was fast and completed to a very high standard. He was also very helpful. We would highly recommend E&A Windows and will definitely use them again for any future double glazing needs. Thanks so much!

Very professional service! During my initial consultation, I was fortunate enough to deal with the owner of the company. He visited my property and spent a few hours talking me through design options and his recommendations. His recommendations were very insightful and ensured my build looked elegant and modern while retaining the functionality required for an active family of 4. The build process was equally professional with the construction team arriving when they said, treating my property with respect and cleaning up after they finished each day...something not often done by today's tradesmen. I've recommend this company to my parents.

I have just had new windows installed by E&A Windows and I must say I was very impressed. Arthur the owner of the company was so helpful and supportive throughout the process. I don't know much about windows so was skeptical at first, but I felt at ease very quickly. The guys who came to fit the windows (John, Christie and Peter) were absolute legends. They were extremely friendly and so so helpful, and the respect they gave me, my elderly parents and our home was exceptional. They took care of our home as if it was their own. I have never come across such professionals, not only did they do a fantastic job , but they went well beyond, seemed like nothing was impossible. They were with us only for 3 days but my parents were actually sad to see them go. I would highly recommend them to anyone looking to fit new windows.
