IMPORTANT NOTE: This product is subject to regional limitations, please check availability on the "regions" tab.

The VELUX solar centre-pivot roof window GLU is powered by daylight via an integrated solar cell and operated with a wireless wall switch for ultimate convenience. A built-in rain sensor ensures peace of mind by automatically closing the window at the first sign of rain. Its moisture-resistant surface makes it ideal for kitchens and bathrooms. The window is as easy to install as a manual window, as no wiring is needed.

The window can be installed in roof pitches between 15° and 90° to the horizontal. Note: A combination of roof pitches, window sizes, cover materials and accessories might hinder parking of the sash in some open positions.
