Welded steel construction plays to its strengths in sloping glazing. Ultra-slimline profiles also allow designers to create large roof lights. The TVS sealing principle is perfect for sloping glazing applications but can also be easily combined with VISS vertical facades. Just as in loadbearing constructions, the same seal can be installed to run continuously from a sloping to a vertical inclination.
