Insulated system for inwards and outwards opening steel windows with extremely narrow face widths and concealed fittings. For outdoor use on listed buildings.

The forster unico xs system made from 100 percent steel, without synthetic insulating materials, and for outward-opening top-hung and turning windows as well as inward-opening turn/tilt windows and fixed glazing demonstrates the advantages it offers in listed industrial buildings in particular, thanks also to its freely bendable profiles. The extremely filigree and robust system permits leaf sizes of up to 1440 x 2440 mm, which allows for a great deal of design freedom and plenty of natural light.
