The Fantastik-ST 80 is our passive grade solution for an all-steel window system. It has a moderate depth that can handle a wide triple-pane glazing unit to make almost all applications passive house grade. The multiple-chambered profile system has a modern square exterior shape and can handle up to a 52mm-wide glazing unit--this means that it can even theoretically handle a quad-pane glazing unit. As with our other steel profiles, there is an option to upgrade to a full stainless steel construction for a truly stunning appearance! The extremely wide thermal break connector made of fiberglass-reinforced polyurethane provides a very high level of thermal performance for an all-steel profile. This is a window system for those very few select clients who want a relatively slim-profile steel window but do not want to compromise thermal performance when compared to systems made from other typically warmer materials. Two profile heights are available at 50mm & 70mm in Fixed configuration. Even the higher-height 70mm version is lower than most uPVC, wood, and aluminum profiles readily available on the market. The 50mm version is suitable to replace windows in old industrial buildings and warehouses where the look of the original slim steel windows has to be closely matched but where the buildings need to be highly energy efficient in their new use, especially if it is residential use.
