“Keylite is a truly innovative product within its category, they have set the standard with their unique innovations such as the thermal collar and ventilation system, which enhance the performance of the window, and as a result the room. We have also worked closely in partnership to develop a bespoke quad lite window system that met the exact needs of our house type range”

“Keylite’s continuous stream of product innovations helps us to achieve the optimum build performance. The performance gap and minimising thermal bridging is a key issue that builders face, and their integrated thermal collar helps to address that problem, by being a built in solution. From a design perspective again it delivers that external streamlined finish we need for our homes”
