(9 reviews)VIU is an additional fixed element that can be installed vertically below a centre pivot or top-hung roof window on roof pitches between 15-55°.
The VIU 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.
