Inspired by products that are commonly found in Europe, the Evolution Series 9000 tilt-and-turn aluminum window offers the dual-action functionality of a hopper and a casement. The tilt-in feature provides a 4-inch opening at the top for indirect ventilation, and the swing-in casement operation provides full-opening ventilation and easy access.
