The adhesive require moisture to cure, if it's too cold the adhesive can't cure fully.

From experience of my own and others, I'd be watching them done it.
I had one very well known company do the windscreen on a car under insurance and them scratched the roof and goudged some seals far from the windscreen, they of course didn't own up to it.
You have to use some pretty sharp tools to remove the old sealant, one slip and it's bye bye paint work.

So no Windscreens can be fitted, virtually anywhere, unless you've got a heated garage.

This is true, if the air is too damp or too cold it 'may' compromise the safety of the vehicle. The quality and application of both the bond (adhesive) and the primer is critical. In most modern cars with bonded screens the structural integrity of the bodyshell relies on this. If you are unfortunate enough to be in a crash where a car rolls you really don't want the screen either falling out or being pushed out by deployment of an airbag. There are very strict 'use by' dates on the primer and bond, and 'drive off' times after the bond has been applied. I saw a Rover last week where the screen virtually fell out, it didn't need to be cut out. It was the original manufacturers screen and had not been fitted properly in the factory. The result is a load of rust where the screen fits - this makes it totally unfit for road use and may end in the vehicle being scrapped. The owner is annoyed that the company can't release the car to be driven away but he'd be a lot more annoyed if he had a serious crash in it and his airbag wasn't effective because the screen fell out.
