REACHING TOP PERFORMANCE WITH OPERATING AND FIXED DESIGNS
The outstanding performance of the System 4500 window design is one of North America’s best-kept fenestration secrets. uPVC windows not only far exceed aluminum on thermal performance; they can also meet the highest available structural standards.
Top Performance, Intelligent Design, Timeless Style
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
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.
