SL 82

Aluminium, heat-insulated according to the latest German energy saving regulation (EnEV)

The SL 82 is a heat-insulated folding glass door with a full glass look and a flat exterior glass surface. This innovative product is based on our tried and tested SL 80 folding glass door system but appears virtually frameless. In spite of being a mere 8 mm in width, the aluminium surround provides optimal edge protection for the glazing. The all-over all-glass look is achieved using stepped-edge glazing that covers the section.

SL 82: iF product design Award 2010 & red dot product design award 2010
The internationally renowned Hanover-based iF Design Forum subjects submitted products to a total of 12 evaluation criteria, including design quality, processing, material selection and “Universal Design”.The Red dot design award is an internationally recognised competition, whose prize, the red dot, is regarded among experts as a true mark of quality and good design. With more than 12,000 participants from more than 60 nations, the red dot design award is one of the biggest design competitions in the world. With its new SL 82 folding glass door, Solarlux truly has its finger on the pulse. “A new dimension in design” is the motto of the folding door with its all-glass look.
