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 U_f 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).

• high thermal insulation with low design depth
• proven performance features, combined with heroal WF and heroal WF EM fittings
• comprehensive range for every application

Energy efficiency counts: the S 77 HI profile system is the next logical step in the development of the heroal S 77 lift and slide system, and offers a modular insulation zone and sealing technology at three levels for sealing the leaves and central joint. This allows the system to achieve U_W values of ≥ 1.0 W/m²K. High-quality, economical insulation materials are used in the parts of the lift and slide door that are most crucial to heat retention.

The heroal D 72 door system offers functional versatility with a range of opening types for typical heroal performance features. The tested and certified heroal system allows all conventional types of openings to be implemented, including tested emergency exits and escape routes (according to DIN EN 179/1125), ­automatic door systems, finger guard doors and burglar-resistant doors – also with the emergency exit door function.

The design of the thermally insulated heroal C 50 curtain wall system is ideal for use as a vertical or vertical-bending transommullion, transom-transom or mullion-mullion curtain wall. The system can also be used as a roof area, light roof pyramid or conservatory. A variety of cover and pressure profiles adds the finishing touch to the range of systems. The heroal C 50 curtain wall system achieves heat insulation values of up to U_f = 1.2 W/m²K and enables optimised ventilation as well as drainage.
