Specifications

Engineered to the highest standards

Slender aluminium profiles combine with highly insulated glass units, giving you some of the most energy-efficient sliding doors on the market.

Warm in winter, stunning in the summer

It’s the glass that’s just one clue to the impressive specifications of Cortizo sliding doors. You get toughened safety glass, having a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill. The result is U-Values designed to keep you comfortable in the winter, cooler in the summer and save money on your energy bills.  You can also upgrade the glass to triple glazing, laminated, acoustic or solar control.

The thin aluminium profiles come with built-in insulation preventing cold bridging and providing enhanced insulation throughout.  In the winter months, sophisticated seals, hidden drainage and clever design protects your home from the cold, wind and rain.

Smooth sliding glass walls

Engineered to last

The advanced engineering, incredible quality and high performance of Cortizo sliding doors make a design statement in your home.

Whether you want to replace your dated patio doors or create your Grand Designs style home extension, these doors are for you.

I would absolutely recommend Aspire Bifolds. They provided a great product at a reasonable price. Installation team was friendly and professional. They installed in less than a day.We also encountered a small issue with the measurement of the doors, but the leadership at Aspire was quick to cover additional costs incurred to rectify the issue. We really appreciated their professionalism on this matter.

Aspire bifolds removed some old wooden sliding doors and replaced them with some lovely French doors. They did a fantastic job- they spent time with me to ensure I had made the right choice of door, it took no time to fit them and the fitter was friendly, polite, clean and courteous. Quote was competitive and I couldn’t recommend them enough!

We went with Aspire after getting a few quotes, they weren't the cheapest but were still competitive. We chose them on the basis of their reviews and I am really glad we did! The service has been excellent throughout, our doors were installed far quicker than we were expecting, the fitter's attention to detail is great, and the quality of the doors is fantastic.After installation we did have a few problems with finding marks on the glass, which is provided by another firm, and had a few panes replaced. John, the director, ended up coming round himself and offered to replace the final pane. I know that many firms would just have ignored our calls once we had paid everything, so to have this level of service was fantastic. This proved our decision to go with a slightly more expensive firm in Aspire was the right move!

We recently used Aspire for purchase and installation of smart system heritage doors for our extension. We are thrilled with the finished product. John and the team are brilliant, every person I spoke to was helpful and friendly. Email response was really fast. The whole process from start to finish was seamless and stress free.The installers were efficient and tidy, they left the place cleaner than when they arrived. Following installation we noticed a scratch on one of the panes, we thought it could be buffed out, but the whole pane was replaced without issue within a week.It is rare to find a company with such great customer service and work ethic these days. I would certainly be happy recommending Aspire to anyone.

I visited Aspire Bifolds to discuss some technical details of the installation requirement for sliding doors. Both of the staff I dealt with were friendly and helpful and in particular Ji was able to answer all of my questions and demonstrate some of the details on the door installation in the showroom. Overall a very helpful visit.

The doors and blinds look brilliant. Dealing with Aspire was very efficient from browsing and ordering to fitting, absolutely great from start to finish. Very professional and exact with advice and information. We opted for the solar integrated blinds and love them. When it’s dark and the blinds are closed we still get to enjoy the expanse and look of the doors. Definitely recommend Aspire.

We were looking for specific style of windows and found that Aspire met those expectations. Our initial meeting with John was crucial to us as we needed him to understand the period that we were looking at. Their team are dedicated to ensuing quality. The fitters they have also share the same ethos of ensuring quality. We highly recommend Aspire as a preferred window company. We will be coming back to them to replace our other windows in due course.
