The VELUX top-operated, centre-pivot roof window GLU 0061/GLU 0561 delivers extra energy efficiency, thanks to an exceptionally affordable three-layer glazing. Easy top operation allows furniture to be placed underneath and moisture-resistant, maintenance-free finish makes this window ideal for any room especially bathrooms and kitchen.

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.
