An intelligent combination of geometry and material enables the new heroal W 77 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”.

Window systems
Innovative, future-oriented window systems demand the highest quality with minimal energy and material consumption during manufacture and maximum efficiency for energy and costs throughout the lifetime of a product. To ensure the unique level of heroal quality, it has always been our policy to carry out the key production steps in our own factories, applying our own expertise. heroal has developed an innovative system solution for durable aluminium windows in line with this guiding principle, which is setting new standards – heroal W 72.
