The tilt-turn is the dominant window style in Europe, now gaining popularity among discerning architects, designers and homeowners in North America. The unique tilt-turn hardware allows each unit to tilt at the top for ideal indirect ventilation or swing in for easy cleaning or emergency egress. Both actions are activated by the turn of a lever, which controls all the mechanics within the frame. This high performance system is second to none in energy efficiency, sound insulation and security – earning stringent commercial ratings. Many options, sizes and configurations are available to meet virtually any styling or performance requirement.
