Just to add that I've never had a window pane crack on me whilst using a heat gun. I think common sense is the key to using one & if it's very cold, you obviously have to gradually warm the panel up evenly.

As Peter says, if you concentrate heat in one area for a long period, you're asking for trouble.

On a similar note, I've also never had a cracked windscreen by pouring warm water on it when frozen contrary to popular belief/myth. Now if you were to tip boiling hot onto it, that would be a different story & the same level of stupidity as pouring hot water into a cold glass tumbler.

It's all about thermal expansion folks

-3? Is it a girls car...? It was minus 15 here at the coldest and no cracked windscreens... I don't really care though just wanted to sound like I can handle the cold even though I never went too far from the comfort of a heater!

Yes it is a girls car - it's Alisons. I usually drive the van but had to take the car to work that day

Well the man came and fitted a new screen today. On closer inspection there was a slight stone chip on the outside that is suspected of causing the crack.

Alison has now been absolved of all suspicions of causing the crack. Her defence of "I don't have any diamond rings - they're all cubic Zircona you cheapskate" has been accepted as a suitable alibi

Not really - you're accused of mudslinging
