St. Cloud Window Inc. has made available its SCW 3530 Tilt-Turn window, which has two open positions with one handle controlling all operations. With a 90-degree turn of the handle, the tilt-turn hardware allows the window to tilt inward at the head for secure ventilation and worry-free protection from the elements. Alternatively, turning the handle 180-degrees allows the vent to swing inward like a casement window for easy cleaning or a full breeze. Turning the handle to the downward vertical position securely locks the vent with a full compression seal. The window is engineered and tested to meet standards for acoustic performance, energy efficiency, water penetration, impact resistance and security.
