/heroal W77 HI
The window system to meet
present and future needs
An intelligent combination of geometry and material enables the new heroal W77 window system to achieve a Uf value of 0.95W/m²K (view width: 120 mm) at passive-house level, with an installation depth of just 77 mm. With this development, heroal has designed the thermally separated aluminium window in such a way that it not only meets present demands stated by the 2016 German Energy Savings Regulation (Energieeinsparverordnung, EnEV) over the long term, but also fulfils future requirements for “nearly zero-energy buildings”.
