heroal W 77 HI

heroal - Johann Henkenjohann GmbH & Co. KG

Description

The window system of today and tomorrow

Thanks to the intelligent combination of geometry and material, the new heroal W 77 window system achieves a U_f value of 0.95 W/m²K (face width 120 mm) at passive house level with an installation depth of only 77 mm. Thanks to this development, heroal has succeeded in aligning the thermally separated aluminium window in the long term not only with the requirements of today, EnEV 2016, but also with the requirements of tomorrow "nearly zero-energy buildings".
