A window which can either tilt inwards at the top, or can open
inwards hinged at the side. This is by far the most common type of
window in Germany, its country of origin. It is also widespread in
many other European countries.
The windows offer great energy efficiency and allow you to change
the window opening depending on the time of day and air
The turn property (i.e. swing in) function of the window allows easy cleaning of the outside pane as
the entire pane can easily be accessed from inside. Therefore there is no need to climb ladders or clean
from the outside.
The tilt function gives excellent indirect ventilation. That is any draughts are directed upwards and so
there are a more constant airing. If more ventilation is required at anytime than is allowed by the tilt
function then the window can always be fully opened using the other method
