    The VELUX electric 230 V, centre-pivot roof window GGL is a wired solution that connects seamlessly to any switch range or integrates effortlessly with any building management system - with flexibility built around your needs. Designed for both in-reach and out-of-reach installations, it features a silent, integrated motor and a built-in rain sensor that automatically closes the window when it starts to rain.

    The window is operated electrically from a standard switch (not included with the product). The window operator permits a maximum opening of 200 mm The chain engages and disengages automatically when the window is closed. The window can be manually operated with the control bar on the ventilation flap from a fully closed position. The window can only be operated manually when the electrical motor has not been engaged.

    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.

    Special features
    The roof window is a special ice and snow resistant window fitted with special gaskets, a special bottom frame cover, sealed screws and a triple glazing unit.
