Is it getting difficult to buy ordinary sheet glass - the kind you cut with a diamond or a wheel - in France? I ask because I'm trying to source the stuff on-line using google.fr, for some forthcoming repairs to an old fashioned attic window - and it's proving rather difficult.
I've had this runaround in the UK recently, trying to get a small sheet of ordinary glass for a broken greenhouse window - apparently, glass is now deemed too dangerousin the UK for ordinary mortals to get their mitts on, so only professionals can obtain and fit it (at huge expense) or you have to order pre-sized safety glass (at huge expense). A local firm wanted £50 to come out and fit a 12" square piece of 4mm glass that would have cost a fiver. I wound up going under the rader and swapping some MIG-welding for an offcut - and even then I was sworn to secrecy.
Jeepers! I've been messing about cutting glass pieces from sheet since Pontious Pilate was still in flying school. Each time I nicked myself I put on a band-aid (unaided) to stop the leak (I didn't go to casualty, either) and got back on with the job like a real grown-up. It's not exactly stuntman grade work - or is it nowadays???
Hmmmm - is it worth smuggling the stuff? 
Can anyone pleeeeease suggest somewhere near St Lo/Villedieu-les-Poêles/Coutances where I can buy 4mm glass sheet for home cutting????
