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 Uf 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).

Window systems
The window system heroal W 72 with its numerous variants offers the greatest possible freedom of design – from the planning phase to manufacture. In addition to supplementary elements, such as the ventilation flap heroal W 72 VF and parallel slide and tilt doors (PSK), this system also provides for perfect combinations with the door system heroal D 72. Sash profiles are available with push rod fitting grooves (SBN) and plastic fitting grooves (KBN), which makes a flexible fabrication possible. It is possible to create windows with a high proportion of glass, thanks to the small face width of just 90 mm. The standard heroal W 72 system with a face width of 120 mm achieves a low Uf value of 1.3 W/m²K, and can be further enhanced or extended. System extensions are heroal W 72 (w/o PU foam – reduction in U value through modification of the profile sealing zone and the use of alternative insulating material), heroal W 72 HI (Highly Insulated - enhancement of the U value through the use of different sealings and insulations) and heroal W 77 UD (Universal Design - French doors with a threshold height < 20 mm).
