GGL is a an electrically operated or solar powered centre pivot roof window that can be installed on roof pitches from 15-90°. Operation is via a simple convenient wall switch, whilst a rain sensor ensures the window closes automatically in the case of rain. The sash can be opened to 200mm (some shorter length windows have smaller opening distance). There is a ventilation flap along the top sash of the window which allows fresh air to enter the room. The chain engages and disengages automatically when the window opens and closes. This allows the window to be opened manually for ease of cleaning of the outer glass pane.

Frame and sash made of laminated pine wood and ventilation flap made of pine wood are finished with triple coat. The exterior of the frame and sash is metal-clad and therefore maintenance-free. The window is equipped with an insulating glass unit.

Externally the window has maintenance-free cover parts.
