VISS Basic and VISS Ixtra are cost-effective and aesthetic system solutions for facade construction and can be mounted on any support. The system construction is based on the proven VISS system. Thanks to this system, very large span facades can be achieved. The choice of the shape and material of the loadbearing construction is unrestricted by the glazing.
