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. heroal W 72 also allows for the simple implementation of façades for stairwells. 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

Available as a heroal plus package.

The heroal D 72 front door system provides exceptional design versatility in a single system. Performance features of the door system can be matched to the construction project and requirements relating to heat insulation, wind load, air permeability, tightness against driving rain and burglary resistance can be tailored to the conditions on site. For heroal fabricators this means maximum flexibility, an end-to-end system logic and greater production reliability.

• Heat insulation values up to U_f of 1.7 W/m²K
• Comprehensive product range for every application
• Large variety of colours and designs

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.
