UNIQUE ULTRA-SLIM PROFILES. Forster unico XS is a system addition that provides thermal insulated window elements and fixed glazing with ultra-slim facings. At the same time, it opens up a diversity of applications for both the heritage classic style of windows with glazing bars and the modern appearance with maximum visible glazing. This applies to the numerous opening variations as well as the possibility of installing fillings up to 60 mm to achieve very low U values and excellent sound insulation values.

The unique profile design made of 100% steel is ideally suited for renovating old or historic buildings and for modern glass constructions.
