GPU VELUX langai

The GPU roof window has an attractive white finish of polyurethane that makes it a great choice for any room. However, it is especially suitable for damp rooms like bathrooms, kitchens and bedrooms, particularly with a low roof pitch.

 In addition to its waterproof surface, the GPU window possesses all the features of the GPL window.

Just like GPL, the GPU roof window has a ventilation flap that will allow 14-28 m3 air flow per hour (depending on window size). 

The double function sash may be opened in both top- and centre-hung positon for easy operation and cleaning.

GPU roof windows are supplied with an extra handle at the bottom sash. This handle is used to open the GPU in the top-hung position. 

The GPU roof window may also be used a rescue opening - if installed and placed according to local building regulations (certain sizes only).

GPU roof windows are supplied as standard with an energy-saving pane with toughened double glazing, pane "59": U-value = 1.2 (= 1.5 for the whole window).

GPU roof windows are especially suited for less sloping roofs (roof pitch from 15o-55o, with optional special springs up to 75o).
