What’s going on here? I’m seeing this more and more on inspections in my area. It appears that the inner gasket between the glass panes are expanding. And with nowhere else to go, they expand/buckle into the space between the glass. Ugly. It’s not just one window manufacturer. Although there’s no fogging of the glass, I assume that it’s safe to say the gas-tight seal is broken or at least compromised.

Joe, what publication is this from?
Try this one instead, Saw the same issue and got lots of good comments on it.
Thanks to all of you for the comments. Very helpful. Got an education of swiggle seal failure.
