The Janisol lift-and-slide door programme re-defines the living room. The proven system, which has been re-developed for large openings, allows the indoors and the outdoors to merge and in this way creates a unique, open living space. The bottom threshold made of high-quality, glass-fibre reinforced plastic makes it possible, on the one hand, to form a disable access threshold and, on the other hand, also guarantees optimal thermal insulation. The Janisol lift-and slide doors are CE-compliant and have been tested at ift Rosenheim.
