Due to their location on a pitched roof rather than an elevation/wall, roof windows can transmit light and heat for longer in a day than vertical windows.
Roof windows with two layers of low-emission coating that reflect both ultraviolet and infrared light, offering more than 80% UV protection combined with heat reflection.
The ideal UV glazing option depends on three factors – climate, application and budget!
Low-emissivity coatings reflect heat radiation back outwards in summer, reducing solar heat gain and minimising reliance on air conditioning.
