How can I find out how much UV protection is afforded by my Citroen Berlingo's windscreen?

I own a Citroen Berlingo XTR first registered in Nov 2009. My wife suffers from Lupus, a disease which can be aggravated by exposure to UV light. I thought it would be a simple matter to ask how much UV protection the windscreen offers from the manufacturer Citroen, through their UK technical team. Numerous requests by email resulted in them eventually telling me that Citroen France would have to answer the question. I then sent emails to the manufacturers of the glass, but they have not even acknowledged my email. Any ideas?

I suggest you use Google to research this. I think an 'Athermic' screen offers some protection, but a normal mildly tinted screen does not, and EC law outlaws a heavily tinted screen.
