heroal W 77 HI/PH

With only 77 mm installation depth, the system not only saves energy, but also material costs as well. Thanks to its numerous innovative and construction-related benefits, it is extremely useful in all ranges of application.


Product Description

As with all heroal systems, the heroal W 77 is based on the guiding principles of sustainability. The basis of this innovative window generation is the profile connection designed by heroal made of aluminium half-shells, insulating bars and an insulation zone completely filled with foam.

An additional integral component of the heroal systems is the heroal hwr surface refinement, produced in our own coating plants and designated as the official GSB Premium Coating.

First class materials, technical perfection down to the tiniest detail and a broad range of design options, ranging from fixed glazing to a barrier-free French door with a casement leaf height of up to 2800 mm are the key characteristics of heroal's efficient system technology.

Depending on the desired classification, the modular construction enables individual planning and realization, due to the fact that the heroal W 77 window system not only meets the EnEV 2016 requirements, but also the KfW 55, KfW 40 requirements and is also passive house certified.
