I watched the Japanese presentation video for the Prius that someone posted the link to. I noticed a slide that seemed to indicate some type of IR / UV rating for the 2004 Prius glass. Does anyone have the specific information about this? I'm particularly curious about any UV protection that the glass may offer.

Thanks.

I've been wondering about the glass
properties too. Is it just the
front windshield, or all the windows?
Will you get the same or better
glass should you need to replace a
window thanks to a rock/fracture/accident?

If anyone is able to get some of
the Prius' windowglass, say after
an accident (don't go smashing any
windows!), if it's bigger than about
a 1/2" diameter (tad smaller than a
US dime) or smaller than about 7"
diameter, I should be able to fit it
into a spectrophotometer at work.
I can scan from about 0.190u (UV)
out to around 50u (far IR) if I had
a sample...

I do have stock glass, UV and IR
quartz, and optical sapphire to
compare it to.
