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. With perfect insulation values (Uw ≥ 0.86 W/m2K) and certified burglary resistance (resistance class RC2), heroal S 77 SL is a high-end, aesthetically appealing and at the same time functional system. As all sliding and lifting-sliding doors by heroal, heroal S 77 SL is also available as a barrier-free version.

  • Frameless glazing of the fixed element
  • All-glass corners, opening or fixed
