Product description

Kömmerling InVitra is a compact, five-chamber system with a depth of 70 mm, which meets all current requirements based on the energy conservation law EnEV. The flat design of the narrow cross-section of the profile allows you optimal penetration of light and greater gain of solar energy. Two levels of sealing guarantees you impermeability of precipitation, optimal wind insulation and outstanding sound insulation. The innovative sealing of the wing fold reduces thermally conditioned air flow and contributes to outstanding thermal insulation values up to Uf = 1.1 W/(m²K). Safe load transfer of heavy glass is guaranteed by centrally positioned reinforcement. As an architect and designer, he not only fulfills legal requirements, but also uses current subsidy programs for clients.
