IMPRESSIVE EXTRAVAGANCE AND UNINTERRUPTED LIVING
System 4500 bi-fold doors are a luxurious solution for spaces that need a wide, unobstructed opening. They 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 beautiful door design uses compression-seal technology for superior sound, air and water performance.
System 4500 bi-fold doors can easily be matched with a variety of window configurations.

FINISHES
REHAU offers the extruded window profiles in four core colors. The proprietary uPVC formulation provides resistance against weathering with above-average quantities of Ti02 stabilizers and impact modifiers protecting against fading from solar radiation. After five years of weather testing in Arizona, REHAU's proprietary profile formulation performed better than standard uPVC. Our surface quality and higher gloss level help repel dirt and improve the trueness of color.

Exterior foil colors have 10-year warranty when applied on the exterior or interior (see warranty for details).
