Steel Skylight – VISS

VISS Roof glazing

Welded steel constructions come into their own in roof glazing. Ultra-slimline profiles also allow designers to create large roof lights. The sealing principle is optimised for roof glazing applications but can also be easily combined with VISS vertical facades. The loadbearing construction can also be installed to run continuously from the slope to the vertical.
