Wooden windows – Sash
Sash wooden windows feature specific up-and-down sliding opening system.
It allows the window to open in a single plane with one or both sashes sliding. Ease and convenience of operation are achieved thanks to the sash lifting mechanism, which can be operated using weights or springs. The lifting mechanism is concealed in a special chamber within the window frame. This unique opening method allows for better use of space inside the room and allows for free air circulation.
