heroal offers door systems for the most diverse uses: doors for commercial or residential use and fire protection doors, including matching thresholds, door panels and fittings. heroal systems achieve maximum values when it comes to energy efficiency, tightness, soundproofing and safety, and provide an especially high degree of functionality and stability. Thanks to individual surface refinement options and heroal’s profile bending and edging service, design knows no limits. As a result of the exclusive partnership with Les Couleurs® Le Corbusier, the new heroal Les Couleurs® Le Corbusier entrance door including panel has been designed and captivates by its exclusive, harmonious combinations of the Le Corbusier colour palette.
