heroal S 77

The versatile aluminium lift and slide system

Versatility is our speciality: heroal S 77 is a modular profile system with a modern design that fulfils the strictest structural requirements. It offers a wide range of profile face widths, is compatible with other heroal systems and comes with an almost unlimited selection of surfaces.

heroal S 77 can also be used to create multi-track design variants and barrier-free systems. Special leaf profile shapes ensure that all sizes and weights of leaf meet the applicable requirements and regulations for heat insulation. The heroal seal technology with three levels and sealed corners – for leaf and central joint sealing – ensures optimum air permeability and tightness against driving rain.
