More light = a better effect

With a special frame structure which extends into the room, the FRF fixed glass roof window allows more light into the room than some competing products. 

The outer pane of the window has a special self-cleaning coating that significantly reduces the need to clean the window.

Relax in comfort

The FRF’s modern glazing unit is highly effective at reducing noise levels, so that even heavy rain will not disturb the peace and quiet of your room. 

The FRF is recommended for rooms where there is no need for extra ventilation. If ventilation is crucial, however, we recommend the electrically-operated RoofLITE+ FRE electric flat glass roof window.

Safety first 

The RoofLITE+ FRF fixed glass roof window consists of two components: a fixed roof window with the symbol FRF, which has a laminated pane, and a flat glass module with the symbol FGT200, which has a toughened pane. This combination provides enhanced glass breakage resistance and eliminates the risk of broken glass falling into the room. Both components are necessary for proper installation.

Easy installation

RoofLITE FRF windows can be installed in most roofs with a pitch of between 5° and 15°. They use the classic installation method, enabling every roofer and installer to install them effortlessly. Installation instructions and all necessary screws and drill bits are supplied with each window.
