Window Tint & Car Temperture

**mm_202** · 07-18-2006, 07:28 PM

Does anyone know how much window tint helps keep a car cool when in sunlight? Im basically looking for a rough guide, something like x* for 35% and y* for 15%, etc.

Im also curious about how much it would help if I got my front windshield tinted, too.

Its for a black car if that helps.

Thanks in advance.

Well i got 5% all around on my car, which is parked in the sun all the time, and after the getting the tint the heat in the car was noticably cool. I don't know how much in terms of temp.

hope it helps

I think that's a tough one. I don't know how you could come up with a degree estimation. Even if you could, you're not tinting the front so any approximation would depend on the car being oriented a certain way at a certain time of day.

Not all heat is going to be from solar radiation either, you'd have to take into account the ambient temperature, how quick the car dissipates heat too.

So a rough guess is more is better

I've got 35% now which helps, but it still gets as hot as hell on a day like today (90F+). Where I live, that's the max for side and rear windows. So I took a different tact, I got the material they use to make the car sunshades. You can see through it, but it blocks 75% of light. I put it in the side rear windows and I'm finishing up the back tonight. Hopefully that helps a bit.

But even then, the heat reflected is still inside the car, which heats up the glass, which heats up the air in the car, etc.

I have 20% tint on my car and I didn't notice one bit of difference. It is going to be hard to tell as shotgunefx has stated above.

Thanks guys for the info. I knew I was asking for way too much, but on the off chance that someone actually had the figures, I would of been very impressed.

Im getting my windows tinted on Friday and am still torn on whether to get 15% or 10%, and whether to get my windowshield tinted, too.
Its hot as hell where I live and if the 10% tint would keep my car even a few degrees cooler then I'd get it. (And I know that 10/15% tint all around is illegal, but thats besides the point.)

Good chance your gonna be cursing the 10% at night time especially when parking...

lol, I had 5% (actually a cop told me it was 3%) all around on my Honda Civic, and that was a bit much. If I was backing out of a really tight spot, I would actually have to roll down my window to see. Thats why Im not going with anything lower then 10%.
But I had it for two years and never really had a single problem with it (besides being stopped 3 times for the dark tint, but never got a ticket for it

)

Well if your car has AC from the factory, the windows usually have a little bit of tint themselves. So while I have 35%, it's would actually should up a bit darker if they tested it with one of those gadgets.

I'd think the tint would help some, but nothing is going to make that huge of a dent in the temperature of a big block of metal sitting in the sun.

I think that's about as illegal as you can get. I would not reccomend doing that...

Peace,
