4500 SERIES
Tilt -Turn/FIixed/Hopper Windows
A very unique product for large openings in both residential and commercial markets.
The tilt-turn is the dominant window style in Europe, now gaining popularity among discerning architects, designers and homeowners in North America. 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.
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.
