The Janisol lifting and sliding door range defines the living space anew. The proven system that has been newly developed for large openings makes the interior and exterior space blend together and creates a unique open living ambiance. On the one hand, the lower threshold profile of high-quality, fiberglass-reinforced plastic allows a disabled-friendly threshold construction and guarantees, on the other hand, an optimal thermal insulation. The Janisol lifting and sliding doors are CE compliant and have been tested by the ift Rosenheim.
