Honestly, I think the verti slide windows make for a better breeze infrastructure than the tilt windows , because the tilt windows can be force shut by sudden strong winds.
And in the summer when I need a strong breeze at night and have to fully open the windows, I have to hold them open with a chair or something because they will slam-shut in the middle of the night.
I complain a lot about silly american building stuff but in the case of breezes, I think the verti slide is superior.
Also, they're more adjustable. Euro windows can do tilt or open, but the vertical slide windows have a range.
That is a good point.
What about a double window, one EU and one US
