Scandinavian windows are characterized by a non-standard design that enables quick opening of the sash to the outside and turning it vertically and horizontally by 180 degrees. The main advantages of this type of windows are:
- tightness (especially in regions with high winds, the sash is pressed against the frame by the wind);
- security (it is much harder to break the window out);
- convenient use (the rotating sash significantly facilitates washing the outside of the window).
