The VitraLight® roof glazing

Vitral VitraLight

The VitraLight flat roof window is an economical, well insulated and easy to install skylight for flat roofs.

The Vitralight flat roof window is completely assembled and delivered so that it only needs to be mounted above the prepared recess in the roof. The frame is highly insulated and has integrated ventilation ducts on all four sides , which prevent condensation in the roof construction. After assembly, the frame is glued for the purpose of a tight seal, for example with roofing felt.


The flat roof window of Vitral has factory sealed, cold bridge insulated A74 glass surfaces in a 45th degree tilt angle. The frame is a sandwich construction with three-layer paint (white) on all interior surfaces. The coverings are made of aluminum, the insulating material of the frame is rock wool 195 mm with vapor barrier on the warning and semipermeable membrane on the cold side. All materials are recyclable.
