This is brilliant. First time in Austria and I’m in awe at the pure genius of this contraption. I’ve been staring at it for 15 minutes. It’s completely obliterated my mind.

  1. We call it a “Fenster”. It’s pretty handy to save a bit on electricity during the day.

    Welcome to the future 😉

  2. I have to say, this is one of the best posts I’ve seen in a long while. First I was zooming in the picture to see if there is anything special, then I was like, uh, why is this person so excited about a normal window and now I’m just happy because you are so happy and excited! Have a great time here!

  3. i don’t remember but i think in the uk you only find sliding windows.

    can’t remember the netherlands but think it was similsr.

    needs less space.

  4. TIL!

    I always thought it’s just the _obvious_ standard configuration of at least halfway recent windows (recent as in “not 100 years old”) to open both ways 😀

  5. I work for a company in central Maine that makes ultra luxury windows. We use this type of hardware often. I was a carpenter for 35 years in the northeast and never saw them used.

  6. You know what? Screw the sarcasm, I guess windows like that *are* pretty neat.

    *almost gets flattened by the balcony door with the worn-out hinge*

  7. Close the window fully. Then try to move the handle to half between 1 and 2 o’clock. Now pull on the handle. Most modern windows will tilt just a tiny bit … this is the so called “Dauerlüften” or “Spaltlüftung” which should also be safe for cats and other pets. Most people don’t know this and it won’t work on old windows but this is a very energy efficient way to let fresh air in and keep the heat/cold out.

  8. Our 35 year old appartment in vienna has it and its probably the most basic thing I could think of.

  9. Americans who see everyday life in Europe and everyday objects like this ARE CHANGED. You start to forget about this stupid shit we argue about in the US and realize that other people don’t have these problems because they want what’s best for everybody.
