Concept Folding® 77 combines a high degree of insulation and comfort with maximum solar transmittance and an amazing appearance. This unusual folding door system allows you to connect the inside of a building with the outside world, while occupying only a small portion of the floor space. Models are available with different opening options, both inward and outward, to meet all your needs. In addition to the standard folding elements, the CF 77 system offers the possibility of constructing a main door in which the first leaf serves as the entrance door, independently of the other folding leaves.
There are 4 door threshold solutions available: high leakage performance, intermediate leakage performance, low threshold, and even a flat threshold to meet all aesthetic and practical requirements. In addition, the CF 77 system is fully compatible with CS systems for windows, doors and curtain walls.
In addition, the CF 77 system is available in a Functional Slim-Line version. This variant features even thinner profiles, making them less visible.
