Our bi-folding door offers many advantages, but the top one is undoubtedly the smooth transition it creates between the inside and the outside. With generous glass fronts that can be opened across almost 100% of their area, the bi-folding door lends living spaces a unique ambience. Unlike traditional sliding doors, which can leave a large section of the opening covered by glass even when fully open, the individual elements of the bi-folding door gather up into a slender bundle of panels to one side – thus guaranteeing unrestricted views.
