Very low installation depths combined with high heat insulation – that's what heroal window systems stand for. The portfolio includes product variants tailored to the very individual requirements of fabricators, architects, planners and builders. The basis for the variants are the two aluminium window systems heroal W 72 and heroal W 77.
The heroal W 72 window system is a versatile system that stands for optimum quality with high energy and cost efficiency – in production as well as throughout its service life. With variants such as heroal W 72 RL or heroal W 72 CL, the system offers solutions for every range of application – from new buildings to renovations. With an installation depth of 72 mm and a view width of 120 mm, heroal W 72 achieves Uf values of 1.3 W/(m²K), thus fulfilling the heat insulation requirements of the German Building Energy Act (GEG 2020).
If higher requirements are placed on heat insulation, the heroal W 77 window system is the ideal solution. The heroal W 77 HI variant with high thermal insulation achieves a significantly better Uf value of 0.95 W/(m²K) with only a slightly larger installation depth of 77 mm and a view width of 120 mm. In addition, heroal offers the heroal W 77 PH variant for use in passive houses with the view width increased to 180 mm. With a Uf value of 0.78 W/(m²K), this even meets the high requirements of the German Dr Feist Passive House Institute for passive house certification. The heroal W 77 PH window system is thus the aluminium compound system with the lowest Uf value and the same installation depth on the German market.
