heroal S 77 SL

heroal - Johann Henkenjohann GmbH & Co. KG

Description

Perfect combination of transparency and thermal insulation

heroal S 77 SL opens up new large-scale dimensions and guarantees maximum transparency with its unique, innovative frame construction. The new heroal lift-and-slide door generation combines a movable monorail leaf with fixed frame glazing with minimal face widths. This frameless, large-scale glazing with clear lines is an almost invisible link between inside and outside and extends the living space beyond its real boundaries. The heroal S 77 SL lift-and-slide system is a new architectural design element and creates a new sense of space.

More Over

The heroal S 77 SL lift-and-slide system strikes a harmonious balance between contemporary design, maximum comfort and consistent functionality. Thanks to its filigree and modular construction details, heroal S 77 SL can be used without restriction in new buildings and renovations.

The heroal S 77 SL/CC insulation variant also enables improved thermal insulation by optimising the design of the centre joint, the thermal weak point of every lift-and-slide door. This optimisation ensures a more comfortable climate in the living space.
