System 4500 folding doors

The REHAU System 4500 Bi-Fold Door Design is a premium solution for spaces that need a wide, unobstructed opening. It can be an alternative to hinged and sliding patio doors, but can also be used to accentuate open plan living. Whether for residential or commercial applications, this unique door design allows sash panels to fold to either side, creating a wide opening without any interruption. This versatile door design uses compression seal technology for superior sound, air and water performance.

Matching windows in a variety of configurations are available.
The system is available in white, beige or clay and can be laminated with solid color or wood-grain foils.
