VISS TVS is a highly insulated system with a Passivhaus certificate and is suitable for a wide range of applications in new or existing buildings. The panel sizes and infill element thicknesses are selected from the system modules to meet the structural engineering requirements and provide the most technically and economically suitable components. The proven sealing system can be combined with customised VISS and VISS Ixtra profiles or with ordinary steel and stainless steel supporting sections.
