The CF (Concept Folding) 77 is a stable, highly insulating profile for aluminum bifold doors with an installation depth of 77 mm. With its aesthetically narrowly framed elements, it provides a generous view of the terrace or exterior, making the interior appear larger.
Depending on individual requirements and the installation situation, the CF 77 can be used to create doors with 2 to 8 elements. Each module can have dimensions of up to 1200 x 3000 mm, glazed elements up to 63 mm thickness and a weight of up to 120 kg. The integrated and centrally installed system with floor rollers ensures user-friendly and easy operation. The first door sash can also be used as a window or French door due to a turning mechanism.
In addition to the design variant "Functional", you can choose the even thinner Slim-Line version CF 77-SL for maximum light incidence. Both the functional and the slim version of this folding door are available with 4 different threshold solutions each.
While the "High Performance" version defies even extreme weather conditions with driving rain and high wind loads, the "Double Weather Seal" version is particularly suitable for renovations and combines high weather resistance with a low threshold. The "Low Treshold" option offers a low treshold with height of 18 mm. very low threshold. With the "Flat Bottom" configuration, a completely level and barrier-free access is guaranteed, which is particularly suitable for very frequently used entrances and exits.
