Big Glass BI-Folding

  • People are continuously looking for ways to maximize their space, as well visually as physically. The Concept Folding 77 offers them the opportunity to optimize the utilization of their rooms, draw-ing the external environment into their homes. Next to the improved space utilization, this innova-tive system offers the advantage of loads of daylight coming in, as well as an aesthetical design. Another practical feature of CF 77 is the optional door locking principle which allows to use the first leaf as an entrance door without affecting the folding capacity of the system.

    A Wide Range of Solutions

    With CF 77, design and user friendliness go hand in hand with high technical performance. The standalone solution exists out of new profiles, accessories and insulation technologies that have specifically been designed for folding systems. It ensures high insulation values (Uf values down to 2.25 W/m2k) that meet stringent local legislation requirements as well as market demands.

    Innovative Functional and Technical Features:

    • Highly thermally insulating
    • Water resistance up to 600 Pa
    • Glazing up to 63mm
    • 2 to 8 vent combinations
    • Burglar resistant variant
    • Large vents sizes
    • In and outward opening using the same profiles
    • Window or door functionality for the first vent
    • Integrated and centrally build-in bottom rolling system
    • High vent weights

    Design Variants

    Next to the functional design, the CF 77 is supplemented with a Slim-Line variant, the CF 77-SL, featuring a narrower visible width. Both designs are available in four different door sill solutions: High Performance, Double Weather Seal, Low Threshold, and Flat Bottom Solution

    The High Performance option offers maximum performance in terms of air, wind and water resistance. The Double Weather Seal solution combines good air, wind and water resistance with decreased threshold and is well suited for renovation projects. The Low Threshold option offers a rise of only 18 mm and finally the Flat Bottom solution allows easy passage and maximum convenience for high traffic.
