Top Swing 180 degrees Window
|A top swing
180 degrees window is a modern outward opening window, where the sash can
be turned approx. 170 degrees on the vertical plane.
This function is especially usable, where it is necessary that the window can be cleaned from the inside.
As the sash turns outside the frame, this type of window also has the advantage, that it can be opened without removing flowers, curtains and other decorations from the windowsill.
