Heroal S 77 is a modular system of profiles with modern patterns, which complies with the highest technical and structural requirements. It includes a wide range of profile widths in an external view and it is compatible with other heroal systems and offers almost unlimited selection of the product surface. Using heroal S 77 system, you can also deliver multi-track versions and installations with low thresholds.

The special geometry of wing profiles guarantees fulfilment of all requirements and assumptions relating to thermal insulation in all sizes and weights of wings. The heraol sealing technology with its three levels and use of sealing corners for sealing of wings and medial connection between two wings ensures optimum air flow and protection against driving rain.
