Based on the proven VISS system solution, with VISS SG a high-tech façade in structural glazing design can be implemented efficiently and easily. Glass surfaces up to 2.5 x 5.0 m visibly increase the transparency of the building envelope. Variable glass anchors allow the installation of double or triple insulating glass up to 70 mm unit thickness. Even roof glazing in structural glazing design can be easily implemented with VISS SG. The Jansen VISS SG system can be combined with all VISS profiles of face widths 50 and 60 mm and with the support independent VISS Basic solution.
