A Scandinavian window is typically characterised by the following:

- it is made of wood (eventually of wood/aluminium)
- it opens outwards
- frame and sash are on the outside plane/level with each other

All the Scandinavian Window types have the advantage that they do not require space inside, when the windows are opened.

As a Scandinavian window is placed in the front of the wall opening, there is plenty of space for curtains, flowers and other decorations. The reversible window types are easily cleaned from the inside. As these windows opens outward, the wind pressure helps keeping the windows tight.
