heroal S 77 SL
heroal S 77 SL opens up new large dimensions and guarantees maximum transparency with its unique innovative frame construction.
The new generation of heroal lifting-sliding doors combines a movable monorail casement with fixed frame glazing and minimal view widths. This large frameless glazing with clean lines forms an almost invisible link between the inside and outside, extending the living space beyond its actual limits. The heroal S 77 SL lifting-sliding system is a new architectural design element that creates a new sense of space.
In addition to the classic corner coupling with two lifting-sliding elements, heroal also offers a 90° frame coupling with an all-glass door corner constructed from insulation glass as an additional design variant. The innovative and sophisticated design variant of the heroal S 77 SL lifting-sliding system completely satisfies the increasing demand for more transparency in architecture.
This attractive design variant provides light and vitality and even in the joint area the element frame does not restrict your view. heroal’s elegant detailed solution impresses from both an interior and exterior perspective and creates additional architectural accents.
