GDL is a roof balcony consisting of an upper and lower section and can be installed on roof pitches from 35-53°.  The upper section is top-hung and can remain open in any position up to an angle of 45°.  The window is operated from a handle on the bottom of the sash.  There is a ventilation flap along the top sash of the window which allows fresh air to enter the room.  For ease of cleaning of the outer glass pane, the window can also be operated as centre-pivot.

The lower section is bottom-hung and operated with two handles on the top of the sash.  When the upper section is opened, the lower section can be pushed outwards to the vertical position.  As the lower section opens, integrated bannister railings automatically slide into position.

The frames and sashes are made of high-quality laminated pinewood coated with impregnation and layers of water-based acrylic clear lacquer or white paint.

Externally the window has maintenance-free cover parts.
