A system
Completely Thought Trough
Clip in instead of drilling
The frischluft window sill is simply hung on the window frame in two easy steps. No drilling or gluing is necessary!
Tilting is possible without any problems
It is still possible to tilt the window. The tilt angle is so small that objects generally do not slip. For extra safety, you can extend the frischluft with our "tilt bar" .
The window opens completely
You choose the board so that it fits flush against the wall when opened and does not hit it. The window can then be opened as usual.
Our board carries 5kg+
The frischluft is very sturdily built and can carry at least 5kg. In general, a load of more than 5kg is also possible without any problems.
