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.
