Invite nature inside

 

CF 77 blends superb insulation and comfort with optimal solar penetration and an impressive appearance. This exceptional folding door system seamlessly connects the interior of the building with the outdoors while utilizing minimal floor space. It offers various opening options, inward and outward, to cater to diverse preferences. Moreover, the CF 77 system presents the option of incorporating a primary door, where the initial leaf functions as the entrance independently of the other folding leaves.

 

There are four door threshold solutions available: high, intermediate, low, and even a flat threshold, ensuring both aesthetic appeal and practical functionality. Additionally, the CF 77 system seamlessly integrates with CS systems for windows, doors, and curtain walls.

 

Furthermore, the CF 77 system is offered in a Functional Slim-Line version, featuring even sleeker profiles for a more discreet appearance.
