Sliding doors are undoubtedly in vogue. Yet our idea of sliding doors goes back a long way. With an idea that first saw the light of day over 50 years ago, we created our unique lift-and-slide design. The result is a featherweight design, even though we never cut corners on solid and heavy materials. Our solution gives proven weatherproofness and the design also enables supporting pillars to be incorporated into our sliding doors. But above all, it gives a unique feeling. Try, compare and you will see.
