Operation of tilt and turn windows couldn’t be more simple. A handle determines selection of the frame’s multi-point locking mechanism. All lock positions can be achieved with an easy one-handed action. The handle positions include ‘down’ for locked, to one ‘side’ to open the window in the turn position or ‘upwards’ to move the window into the tilt position. When closed, all the locks are engaged and can be deadlocked by key. The number of locking points are determined by the size of the window. In this position, a seal is created that very effectively prevents passage of sound, heat or cold air.
