Product family


Doors and windows with thermal break – In steel and stainless steel

System for energy efficient windows, doors and screens

Sustainable, ecological, 100% steel
Forster unico is the revolutionary, thermally insulated profile system for single and double-leaf doors, for windows as well as for exterior glazed units. The basic profiles comprise 100% recyclable steel and contain no 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.
The impressive slim aspects of window elements combine architectural design, comfort and well-being with excellent heat and sound insulation.
This is the latest technology, energy efficiency, attractive design and the ecological use of materials for a responsible and sustainable construction.

Forster unico Hi
Forster unico Hi combines all the benefits of standard Forster unico systems with even higher insulation parameters. The system complies with the latest requirements for heat protection, e.g. EnEV 2009 (DE) and SIA 380/1 (CH).
The structural profile depth allows the integration of 2- or 3-pane insulated glazing – for Uw values of up to 0.9 W/(m2.K).
Simple construction: Only two additional components are needed to make Forster unico into a very efficient heat insulating Forster unico Hi element.
