The Marvin Tilt Turn window is a European-style window with two distinct functions: swing it in like a door or tilt the top of the sash into your room for ventilation. One handle controls both operations. The tilt turn is a great window for unique situations where you want additional ventilation or access. For example, in European designs it is often used as an alternative to a door for access to a Juliet balcony and it can work well in remodeling project where an egress option is needed.
