Bring nature indoors
combines a high degree of insulation and comfort with maximum sunlight permeability and an amazing appearance. This extraordinary folding door system allows the interior of the building to be connected to the outside world, while taking up only a small part of the usable area. Models are available with different opening options, both inwards and outwards, to meet all your expectations. In addition to standard folding elements, the CF 77 system offers the possibility of constructing main doors, in which the first leaf serves as the entrance door, independently of the other folding leaves.
There are 4 door threshold solutions available: with high tightness parameters, with intermediate tightness parameters, with a low threshold and even with a flat threshold, to meet all aesthetic and practical requirements. Additionally, 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 the Functional Slim-Line version. This variant is characterized by even thinner profiles, making them less visible.
