The Schüco FWS 35 PD facade system enables buildings to have all-glass corners with a slim appearance. This is made possible by doing away with vertical mullion profiles on the corners. This solution creates a harmonious appearance without any distracting elements and lets as much light as possible into the interior. Furthermore, the reliable equipment for opening the window is integrated into the system and concealed from view. If required, a sun-protection system may be installed to reduce the need for cooling and therefore reduce energy consumption.
