Fully customisable uPVC bifold doors

Aspect uPVC bifold doors are a fully customisable high performing door system. Designed to seamlessly connect interior and exterior living space, they slide smoothly open, folding neatly to one side to create an ultra-wide opening. Aspect bifolds can incorporate a traffic door into their design. This functions just like a normal door and can be used for easy access when you don’t want to open the whole system. With dual colour options and a selection of different thresholds to choose from, Aspect bifolds are a great choice for both residential and commercial applications.

As installers of both PVCu and Aluminium to the New Build market, the importance of on time delivery is totally time critical.
Over the last 20 years Quantum windows have worked closely with PGB to partner with us and deliver our offer to site.
Highly professional, and a pleasure to have worked with them so closely over the years.
