European Aluminum Bi-Folds


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, drawing the external environment into their homes. Next to the improved space utilization, this innovative 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/m2 K) that meet stringent local legislation requirements as well as market demands. Available in a number of configurations using between 2 and 8 door leaves, you can choose a design where the complete set of vents stacks to the same side, or split the design at any position, possibly integrating a central door solution.
