heroal S 77 HI

The highly insulated aluminium lift and slide system

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.
