The System 4500 design offers 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. This versatile design is 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.
With the System 4500 design, tilt-turn, awning, hopper and fixed configurations are possible. 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.
