Construction

VELUX GGU is an opening, centrepivoting roof window used for in-reach applications to bring natural light and air into attic or loft rooms where ventilation is required. Easy to clean, high quality polyurethane molded over a timber core and finished in white. Aluminium external cappings finished in a smooth grey colour, similar to ‘COLORSTEEL® Grey Friars’.

Operation

The GGU is operated manually. The control bar at the top of the window is clicked to allow passive ventilation, whilst the window remains locked and watertight. A second click of the control bar opens the sash. The sash is frictioned to stay in a horizontal pivot position to maximise ventilation. The sash can be locked in two positions, either slightly ajar or 180°, the fully rotated position, allows the outside pane to be cleaned safely from inside the room.
