Do windows filter UV rays?

Thanks!
There is increasing knowledge about the hazards of solar and ultraviolet (UV) radiation to humans. Although people spend a significant time in cars, data on UV exposure during traveling are lacking. The aim of this study was to obtain basic information on personal UV exposure in cars. Methods: UV transmission of car glass samples, windscreen, side and back windows and sunroof, was determined. UV exposure of passengers was evaluated in seven German middle-class cars, fitted with three different types of car windows. UV doses were measured with open or closed windows/sunroof of Mercedes-Benz E 220 T, E 320, and S 500, and in an open convertible car (Mercedes-Benz CLK). Bacillus subtilis spore film dosimeters (Viospor) were attached to the front, vertex, cheeks, upper arms, forearms and thighs of ‘adult’ and ‘child’ dummies. Results: UV wavelengths longer than >335 nm were transmitted through car windows, and UV irradiation >380 nm was transmitted through compound glass windscreens. There was some variation in the spectral transmission of side windows according to the type of glass. On the arms, UV exposure was 3–4% of ambient radiation when the car windows were shut, and 25–31% of ambient radiation when the windows were open. In the open convertible car, the relative personal doses reached 62% of ambient radiation. Conclusions: The car glass types examined offer substantial protection against short-wave UV radiation. Professional drivers should keep car windows closed on sunny days to reduce occupational UV exposure. In individuals with polymorphic light eruption, produced by long-wave UVA, additional protection by plastic films, clothes or sunscreens appears necessary.

Does UV radiation come through glass?
Ordinary car window glass filters out about 97% of the UV-B radiation and about 37% of UV-A radiation. It is approximately equivalent to a good sunscreen, which means that if you’re sitting in the sun during a long trip you could still get burnt from the amount of radiation coming through the glass. Laminated windscreens block all of the UV-B radiation and about 80% of the UV-A radiation.
^^^^^^
because of this lol regular windows blocks 97% of UV-B rays and only 37% of UV-A rays and tint blocks 80% of it. thats double of what regular windows do. Plus tinting windows keeps your car cooler in the summer.

Or 2 car car port. I don't think that will happen soon

). There's only so much you can do to tart up your car and then it's still your old car - just tarted up!I had planned on keeping mine for the very long term (as you have done) unless something outrageous becomes available. I doubt that anything that outrageous will come around so I'm not holding my breath. Before last Memorial Day, it never occurred to me to get a Mercedes Benz and now I have tow of them! Strange world...
I would like to trade my wife's '06 C230 for my neighbor's '08 C300 (with some cash, of course). Our neighbor really likes my wife's car and my wife really likes her car, but the $10K difference is prohibitive for us and we certainly wouldn't want to be unfair to our neighbor.
I think that's just the nature of cars. The new ones seem so much cooler than older ones and that seems to be accelerated with all the neat electronics that are available.
Lexus makes a nice car so if you go that route, you could do a lot worse.
Keep us posted...
My car is black on black and ever since I got my tint I noticed a huge temperature change to when I first enter the car when parked outside.

Then there is the engine noise which seems much louder than it used to be. And the drivetrain noise under power and over bumps. I'm no longer sure I am interested in even small repairs anymore, and I know I am NOT doing any big ones at any point. I can't even find the motivation lately to keep it clean.


You have to be somewhat of a fanatic to keep a car past a certain point. I've found it's harder to be a fanatic about a car in the present than in retrospect.

That is why there are more tinting shops in NJ and LA per capita than elsewhere. Miami and Las Vegas are next according to the insurance Risk Rating Institute.
Implants, penile or mammary, and tooth caps, do not require window tinting, according to Rep. Wiener and Suzi Orman.
