Viss facade

Category: Tags: ,


VISS, the fully insulated glazing bar system, is a thermally insulated steel system for mullion-transom constructions.
Whether new build or building in existing fabric – facades of all types and roof glazing can be constructed using only a few modular components. This allows architects and designers to fulfill varying requirements for thermal and sound insulation as well as fire protection while achieving an altogether integrated appearance.

To achieve an efficient structural design of steel facades, VISS offers different load-bearing systems: fully simply supported spans, one side built-in or a continuous beam. The use of welded construction allows complicated elements and tailor-made shapes to be manufactured precisely to requirements. VISS facade systems are tested in accordance with product standard EN 13830.
