INSULATED FOLDING SYSTEMS
BI-FOLD S75-F
Insulated folding systems
The Bi-Fold S75 was developed based on the existing S75 profiles & accessories of windows and doors and was tested by PIV European test facility. It has a very large sash height and width which offers maximum design freedom. The maximum sash height can be up to 3.5 Meters. We have a wide range of configuration options: outward and inward opening folding systems, even and odd number of leaves, combination of passage door with folding systems, for end variations for double-sided folding systems, 90° solutions. Up to 14 leaves can be used in one folding system. The threshold can be recessed into the floor to optimize accessibility. The aesthetic effect is underlined by high-quality
rollers and fittings embedded in the sash profile
