The VELUX solar, centre-pivot roof window GLL adds comfort and convenience to your daily life. Let daylight power your roof window with an integrated solar cell and open the window with a wireless wall switch - easy to use for both in-reach and out-of-reach installations. The built-in rain sensor ensures total peace of mind by automatically closing your roof windows at the first sign of rain.

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