GGL is a manually operated centre pivot roof window that can be installed on roof pitches from 15-90°. Operation is via a control bar along the top of the sash. The sash can be parked in any position up to the horizontal, however the sash can also be fully rotated to allow for ease of cleaning of the outer pane. Roof window GGL is centre-pivoted and operated with a full-width control bar on the ventilation flap of the top sash. The ventilation flap allows fresh air to enter the room through a dust and insect filter.

Frame and sash made of laminated pine wood and ventilation flap made of pine wood are all 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.

The original VELUX top-operated, centre-pivot roof window GGL is easy to operate and gives you the freedom to place furniture underneath. The innovative top control bar allows you to install the window at a lower position to get an excellent view while standing and even when seated.
