GPU is a top-hung roof window that can be installed on roof pitches from 15-55° (and up to 75° with specially manufactured springs). The sash can remain open in any position up to an angle of 45° to enjoy panoramic, uninterrupted views. The window is operated from a handle on the bottom of the sash. There is a ventilation flap along the top sash of the window which allows fresh air to enter the room. For ease of cleaning of the outer glass pane, the window can also be operated as centre-pivot.
The frame and sash are made of high-quality moulded polyurethane around a core of thermally modified timber with a white lacquer finish. Therefore, giving a maintenance free finish.
Externally the window has maintenance-free cover parts.
