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

An additional advantage of the window’s advanced glazing unit and insulation-filled covering elements is its high noise reduction coefficient, which means that rainfall and road noise are largely suppressed.

Durable, safe design

The FRE window is manufactured from high-quality PVC with extra insulation inside the covering elements to ensure high quality. It consists of two components: an electrically opening roof window with the FRE symbol, which has a laminated pane, and a flat glass module with the FGT200 symbol, 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.

Ventilation on demand

The window is operated using a wireless wall switch supplied with the window.  The remote control is factory-paired with the window and the entire system is io-Homecontrol® compatible.

In the event of rain, the window closes automatically thanks to a factory-fitted rain sensor.

The drive motor and cables are hidden in the window frame to give the window an attractive appearance from the inside.

A universal solution that’s easy to install

FRE 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.
