4500 Windows: Commercial

Tilt-Turn: Hopper, Fixed

Three Windows in One

Choosing this design is like getting three windows in one: the in-swing function of the turn position; a convenient, top ventilating tilt position; and an elegant picture window when closed. Elements Architectural PVCu System 4500 offers the ultimate in high performance and are gaining popularity in North America through applications in custom residential homes.

Operating the Tilt-Turn

When the window is closed, simply turn the lever downward 90 degrees to allow it to open by swinging inward. Similarly, when the window is closed, turn the lever downward 180 degrees. With a slight pull, the top of the window opens for ventilation.
