The tilt-turn window, originating in Europe and popularized by passive-house and net-zero construction, is a window type with the unique characteristic of being both an inward-swing casement style window as well as a top opening hopper style window. The clever hinge and intuitive handle mechanism is specially designed to allow seamless switching between the modes via the orientation of the handle. Depending on the handle position, it can operate as a fixed window (handle in the 6 o'clock position), inward casement window (handle in the 9 o'clock position) or hopper window (handle in the 12 o'clock position). This window style combines the security, air-tightness, egress requirements and ease of cleaning of an inswing casement with the all-weather ventilation convenience of a hopper.
