heroal W 72 i

The block window system heroal W 72 i stands for a wide range of architectural designs, made possible through subtle, slim face widths. Sash profiles are not only available with push rod fitting grooves (SBN) and plastic fitting grooves (KBN), but also as interior and exterior glazing, which makes a flexible fabrication and installation possible. The minimum face width for this system is just 81 mm. heroal W 72 i combines a maximum proportion of glass with a modern design without a visible sash, and at the same time offers a high thermal efficiency. It stands for versatile uses, for example as insert element in a curtain wall. The standard heroal W 72 i system with a face width of 87/91 mm achieves a U_f value of 1.5/1.7 W/m²K, and can be further enhanced or extended. System extensions are heroal W 72 i (w/o PU foam – reduction in U value through the elimination of the profile sealing zone and the use of alternative insulating material) and heroal W 72 i UD (Universal Design – block French doors with a threshold height < 20 mm).
