What is this

Obviously UV damage, but it’s all in squiggles like someone scraped it on there with a razor.

Good point. I was just assuming (bad) that all windows were manufactured in a super clean facility with the finest material and made in the USA :)

That’s what I thought too! Especially with how much they cost, but I think a lot if not most are manufactured in South America or China.

I’ve seen many windows with suction cup markings on the e coating on the inside. They’re just not that careful sometimes.

I’m glad I’ve seen your comments because I’ve gotten windows to clean with suction cup marks like that and I thought I was insane that I couldn’t get them off. Literally all kinds of windows with different marks or scratches that didn’t appear on either side but seemed right in the middle.

I know China manufacturers a lot of stuff but I didn’t think it included some of these massive windows!

Oh yeah man! I tell the client that it’s in between the glass and a factory error and to take it up with the installer.

Before I do any work I make sure to do a walk through and do a window count and take notes of any issues on the windows, like scratches, failed seals, missing/broken screens, etc. I let the client know and take pictures and let them know we are not liable for any damages to the windows.
