For totally maintenance free performance, even in damp environments such as bathrooms and en suites, select our Polar White PVC roof window with its excellent U-Value of 1.2 W/m2.K.
In the event of a requirement to upgrade an old roof window to a new Keylite roof window, it is possible to use a renovation flashing to minimise the installation work required on the roof.
Our technical experts are on hand to advise and assist you at the design and specification stage.
Our patents mean that other conventional roof windows do not share many of our extraordinary features.
