The VELUX GGU series roof window is the original center-pivot roof window. The GGU model roof window has been tried and tested for many years. The roof window features polyurethane moulding and is manually operated via the top bar.
Note: Roof windows are not designed to be used in combination with skylights.
Stain Grade wood interior versions of this window are available in all the sizes listed below. Contact us for more information.
One pull of the top control bar allows background ventilation - one further pull opens the window.
Our unique ventilation flap keeps dust and insects out while letting fresh air in.
