The system

Light flooded rooms
The lift-up sliding door, an extension of the Foster unico system, creates not light flooded rooms but also new spacial perceptions. Heights of up to 3.4 m enable spacious glass areas and thus an unobstructed outdoor view.
The door leaves open smoothly parallel to element and save lots of interior space. An efficient finishing is guaranteed through optimally co-ordinated system components such as profiles, fittings and accessories.

A revolutionary system
Forster unico is the thermally insulated profile system with fittings and accessories for single and double leaved doors, for windows as well as for external glazing.
The base profiles comprise 100% recyclable steel and contain no environmentally-polluting, synthetic insulating materials – in contrast to all other insulated systems.
This innovation, uniquely evocative of a framework style of construction, satisfies the most stringent demands relating to physical and structural functions.
