Perhaps this was reported before - but I could not find any related thread. My watch is equipped with a UV sensor, and I just thought it would be a good idea to test how good the UV treatment of the Prius windows is. Conditions: sunny day, UV index: 8.2 UV index measured inside the car through all windows indicated: 0.0 Just thought you might be interested to know.
Re: UV treatment is efficient This .pdf file was posted by someone (don't remember who) on here a while back. It indicates what you measured was valid. Good to know.
Re: UV treatment is efficient Actually most of the glass is quite good UV filter. Try using your UV gadget by measuring UV index under other not so geeky glass stuff as Prius's one.
Re: UV treatment is efficient Probably only one of the factors. I could find totally disintegrated plastics stuff which never saw sunlight, which was quite interesting discovery to me.
Re: UV treatment is efficient Today I tried my sensor measuring UV index through standard glass, 1/16th of an inch thick (1.6 mm). Measured UV index outdoor: 7.1 Measured UV index through glass: 3.3
Re: UV treatment is efficient The easiest way to see how great the UV film is on the windows is simply by wearing transitional sun glasses (glasses turn dark, the brighter the sun light). You'll find that transitions will remain 90% clear ... hardly darkening at all, as long as the windows are up. That said, I'm thinking the OP meant that the UV "is effective" rather than efficient.
Re: UV treatment is efficient "I could find totally disintegrated plastics stuff which never saw sunlight, which was quite interesting discovery to me." I understand that ozone is pretty good at breaking down polymers. Makes one wonder about Plasmacluster.
Re: UV treatment is efficient I think some plastics are designed to be UV resistant, hope that's what is used in the car. Also darker colors are more UV resistant because the UV doesn't penetrate as far into the plastic.
