Tilting and sliding PSK balcony windows are an interesting solution and an alternative to traditional double-leaf balconies. The unique mechanism allowing for both sliding and tilting the window is its characteristic feature. Another benefit is the fact that none of the sashes opens inside, where it would take up living space. This gives an impression of a larger gap. In PSK doors, the motion occurs parallel to the fixed leaf (one leaf is fixed, the other moves). The maximum width of the whole construction is approx. 4 m.
