Narrow timber frames

Narrow timber frames

Maximum daylight and glass-dependent optimal U values are benefits in terms of both comfort and energy balance. Thanks to the narrow friezes, users enjoy the advantages of a movable glass front and the frame takes a back seat. Lift&slide doors become design elements in the room. Both the standard lift&slide hardware and steel hook drive gear can be integrated into either timber or timber/aluminium profiles from a height of 76 mm.
