A very unique product for large openings in both residential and commercial markets.

The System 4500 is a versatile design featuring three windows in one: An inward opening casement in the turn position, a secure top-venting hopper in the tilt position and a tightly sealed picture window when closed.
​
Matching doors 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.

FINISHES
CORE COLORS
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.
