heroal S 77 SL
Innovative lifting-sliding door for large-scale transparency
The aluminium lifting-sliding system heroal S 77 SL is an innovative, design-oriented lifting-sliding door for patios, balconies or conservatories. heroal S 77 SL combines large, frameless fixed glazings with moveable monorail sashes, and serves as an almost invisible link between indoors and outdoors. At the same time, this lifting-sliding door offers best insulation values. Additional highlights connecting the interior with the exterior are a corner designed with fixed glazings, and a corner solution that can be opened – both create a unique living experience.
