Aluminium Sliding Doors for New Build Developments

Bespoke Products

Here at OpenSquare Glazing, we appreciate that one size does not suit all. For that reason, our aluminium sliding doors are supplied to order. You can specify the exact systems you’re after for your new build development. That’s the difference between us and a competitor.

Full Design Service

We work with all kinds of contractors, including architects. As a result, we can produce CAD drawings of the new build development, complete with our aluminium sliding doors and any of the other products that we supply and fit. You can see your visions come to life.

Expert Installation

With our full service, which includes survey, specification and design, the eventual fitting will be seamless. Better yet, our in-house team of installers are highly qualified in their trade. You can have complete peace of mind that we’ll complete a thoroughly professional job.

We have an online quote engine you can use to request accurate sliding door prices. The process can be repeated as many times as you like, but doing it once will give an idea of our sliding door costs. We can then contact you to discuss your project in further detail.

Eye Catching Aluminium Doors

We work directly with Cortizo to supply their stunning sliding door system. They deliver innovation in abundance, making them an excellent option for new build projects here in the home counties and London. Their ultra slim sightlines deliver a head turning, sleek visual appeal. This can be enhanced with the option to create a frameless style pocket door.

If the profile is to be visible though and not embedded into the wall, you can select from hundreds of RAL colour options. This includes a bicolour upgrade, whereby you can specify different hues inside to out. Whatever the design vision for your new build project, you can achieve it with these eye catching doors. There is never a need to compromise.

High Performance Sliding Doors

In their quest for visual perfection, Cortizo haven’t ignored the need for sliding doors to be highly functional. The systems we install to new build developments achieve some of the best performance statistics on the market. U-values with 30mm glazing are as low as 1.3 W/m2K. This traps heat within the home, contributing to excellent energy efficiency.

These aluminium sliding  doors also offer weather and soundproofing in equal measure. They keep the elements at bay, while also providing a disconnected, cosy atmosphere when closed. When open, they are great for connecting indoor and outdoor spaces, with the option of as many as six sashes and three rails. They can suit any new build development project.

Where are OpenSquare Glazing based?

We’re located in Chalfont St Giles, which situates us within the south eastern part of Buckinghamshire. As a result, we cover our own county, as well as London and the home counties.

We encourage anyone in that locality to contact us regarding their new build development. Even if you think you’re a little further afield, we’ll happy confirm if we can work with you when you get in touch.

Are aluminium sliding doors better than uPVC?

We firmly believe so, yes. Aluminium can be made slimmer by virtue of its inherent rigidity. This allows sightlines to be cleaner, with larger glazed units fitted and more light transfer for the end user. All the while, aluminium sliding doors offer just as good, if not better performance statistics across the board.

What other doors can OpenSquare Glazing supply and fit?

If you’re looking for an alternative to our aluminium sliding doors, our French and bifold systems can offer a similar function for the homeowner. If you’re looking for something to compliment your supply of sliding doors, we can offer single casement and Smart Designer front doors.

We also offer aluminium windows and roof lanterns.
