heroal S 77 SL

Perfect combination of transparency and heat insulation

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.

The heroal S 77 SL lifting-sliding system creates a harmonised balance between contemporary design, maximum comfort and consistent functionality. Thanks to its elegant and modular construction details, the heroal S 77 SL has unlimited uses in new buildings and renovations.

Additionally, the insulating variant heroal S 77 SL/CC provides for an improved heat insulation due to the optimised design of the central joint, the typical weak point in the insulation of any lifting sliding door. This optimisation creates a comfortable climate in the living spaces.
