Concept Folding® 77 combines high insulation and comfort with maximum transparency and aesthetics. This sliding folding door system optimizes your way of living by drawing the exterior into your home, whilst maintaining maximum usage of existing space. This high performance bi-fold door system offers different opening types, both inward and outward, to meet all possible requirements. Apart from the standard folding elements, CF 77 can feature a main door principle, in which the first leaf is used as an entrance door without affecting the other folding leafs. CF 77 is available in 4 different threshold solutions, from high performance to low and even flush thresholds, in order to perfectly match all comfort and aesthetic requirements. Additionally, the CF 77-concept can perfectly be combined with the CS systems for windows, doors and curtain walls. Furthermore, CF 77 is available in Functional Slim-Line style. This CF 77-SL variant features a slimmer visible profile width.
