To let a breeze into your room, do your windows open out from the bottom or the top?
If your windows are stacked (upper and lower) which part opens and which part stays fixed?
(Germans with 3D windows don’t count. Lüften is a weird cultish ritual and you should all feel bad.)
This atrocity. This is what WW2 was about
This actually looks amazing
They are. They’re really expensive in the States, when you can find them, but almost every modern window (in Bavaria, at least) is one of these. They also come door-sized, so you can either open an outside door to walk through, or tilt it from the top to circulate air.
OP is probably just too dumb to figure out how to work them; they’re fantastic, and I wish they were common here in the States.
Most windows are like this in my country. They are definitely not an atrocity.
