OP, you’re really giving us nothing hereto go by. From the little info you’ve given us, I’d just assume the window is sitting in the frame very loosely. Not sure how else you’d get a ringing noise? Does the noise go away if you lightly touch the glass against the frame?
YKK AP is the window manufacturer www.ykkap.comNot sure how to describe its like a weird echo ringing noise coming from the windows when traffic passes by. Opening the window about 2-3" seems to gets rid of the noise but it’s 90+°F outside . Panes are tight in their frames and weather stripping looks good. Tried sticking foam around to see if it helps.
That’s super weird. I can’t even begin to understand that. Any way to record a video of it happening? If you touch the glass, can you feel the vibrations? Does it go away then? Are there any strange structures outside your house or with the way the walls are angled? I wonder if you added even a small flat plate to let vibrations bounce off of outside your window if they were eliminate this ringing.
