Is it normal for auto glass to shatter or crack in hot weather?


Wiki User

I just had my back windshield replaced 5 days ago (smashed by random Chicago vandals!) and went out to the car this am and it was shattered again, but this time the auto glass guy said it was because it was new glass and we had really hot weather and then a huge storm blew through and it was likely due to the pressure change, this may be an answer if you had a windshield shatter.
