Schüco FWS 50 SG

The Schüco FWS 50 SG (Structural Glazing) façade system offers a minimalist, all-glass look for projects demanding clean lines and high transparency. With a consistent 50 mm face width, this system enables flush-mounted or semi-structural glazing designs, combining sleek aesthetics with robust thermal performance.

Designed for use with double or triple insulating glass, the FWS 50 SG system also integrates seamlessly with Schüco AWS 114 SG outward-opening windows—allowing for automated, large-format ventilation units that retain the façade’s visual uniformity.
