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”.

Lifting-sliding systems
heroal S 77 SL opens up new large dimensions and guarantees maximum transparency with its unique innovative frame construction. The new generation of heroal lifting-sliding doors combines a movable monorail casement with fixed frame glazing and minimal view widths. This large frameless glazing with clean lines forms an almost invisible link between the inside and outside, extending the living space beyond its actual limits. The heroal S 77 SL lifting-sliding system is a new architectural design element that creates a new sense of space.
The heroal S 77 SL lifting-sliding system creates a harmonised balance between contemporary design, maximum comfort and consistent functionality. Thanks to its elegant and modular construction details, the heroal S 77 SL has unlimited uses in new buildings and renovations.
Additionally, the insulating variant heroal S 77 SL/CC provides for an improved heat insulation due to the optimised design of the central joint, the typical weak point in the insulation of any lifting sliding door. This optimisation creates a comfortable climate in the living spaces.
