GIU is an additional fixed element that can be installed directly below a centre pivot or top-hung roof window on roof pitches between 15-90°.  Cleaning of the outer glass pane is by opening the roof window above.

The GIU window allows even more daylight and offers a great view when standing or when seated.

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.
