tint not helping keep my interior cool
 

hey guys

Not sure if this is the right place to post this, but here goes...

I got some high-end ForumlaOne Pinnacle ceramic tint, for all my windows, and AirBlue for my windshield. I thought I'd be greeted by a nice cool interior, considering my exterior is silver...

Nope.

It's hot as hell getting in.

Does anyone else have "ceramic" tint (35% max legal in Hawaii) and actually has a "cool" interior when parking in the full Hawaiian sun for a few hours?

I'm theorizing that the extreme rake of the windshield allows a lot more light into the cabin, and that maybe there is very little keeping out the heat in the light weight roof. (trying to justify the heat with the high expense of tinting the car.)

I think your tint is helping more than you imagine. I have 20% top of the line tint as well (local shop gave their best tint on accident and charged for the lower grade tint I asked for-win for me!). What will help the prevent excessive heat in your car even further will be adding a windshield visor. Trust me it works wonders!

Tint ain't magic. It just reduces the overall heat/radiation entering the compartment at any given moment. But, given enough time, it'll still get pretty much just as hot as not having any tint at all. Your interior is still soaking up heat (just slower than before) and it's still radiating that heat back into the compartment -- and most of that energy is getting in through the lightly-protected windshield and being absorbed by the all-black and readily-radiating solid black dash.

For years and years I ran heavily-tinted vehicles while my wife didn't use any tint at all -- and this was in Texas where 110* wasn't uncommon. In the middle of the day, both the cars would be hotter than hell. Yeah, mine may have been a little bit "cooler", but we're talking maybe 10 degrees difference on an interior approaching 150*. Even the tint sellers don't claim more than a fairly little temperature difference. The interior of a car is un-frickin-believably hot. A few degrees -- hell, even if it was 20 degrees, doesn't make a big difference when it's nearly 150* inside the car. 130* feels just about as unbearably hot as 150* does.

Same goes for the color of a car too -- it makes a FAR smaller difference than people think. It's a degree or two at best. Most of the energy getting into your vehicle is getting in through the glass -- the color of your car means relatively diddily.

The VERY important thing tint provides as far as comfort goes is that it makes it MUCH easier to cool the interior from that hot state and to keep it cool while you're in it.

I got 20% and 35% on mine and it is still hot as well. Tint isnt suppose to help get rid of all the heat. If you want your car to cool down then try facing the butt if the car towards the sun.

I have 35% sides and 15% rear, and it does help because when you leave your windows slightly cracked and the sun is on your bare skin you can definitely tell a difference..

However, the dash retains a ton of heat while sitting out (approx an hour), and even after turning the AC on full blast, you can still feel the heat radiating from between the dash and windshield area..

Hot Socal days are similar to Hawaii minus the humidity. I have tons of family out there, and I visit often, so I know the heat you're talking about.

Tint helps the car stay cooler for longer than a car without tint--but eventually, it'll reach the same hot state if it's left out long enough.

i've found that using a sun shade in the windshield when parked, even if you have tint, is still the most helpful at keeping the interior cooler (especially the seats) when parking in direct sun. i prefer the two-piece shades that fold up compactly vs. the accordian type.

The interior still gets super hot after a couple of hours parking outside. However, while driving, I do feel the difference when the sun is hitting my skin where ceramic tint is applied versus non-tinted windows. It's almost night and day.

Time... The tint slows the heating down but it's not going to stop it at all. Given slightly longer than without tint the car will still get hot as balls. Light can stiff get in.

I can give you a few tips as I work for a tinting company out here in socal.

The best thing you can do is to park your car facing north, and leave your windows cracked. Facing the car north means that the sun will never be getting your windshield (the most vulnerable and largest piece of glass), and cracking the windows means airflow. Not so much that someone can get their arm inside the car, just enough that the air has a way to flow through.

I have 35% all the way around, excluding windshield, on my FRS, and having the tint, plus parking facing north and cracking the windows made a huge difference.

just get 3% like me all around and 70% on windshield :thumbup:

I have ceramic tint on my car as well. I think the heat rejection factor is somewhere around 50%. So like everyone else stated, the interior of the car will get hot, but it will take longer.

Mostly I use the tent as an extra layer of protection on the interior more then a way to keep it cooler. Once I save enough dough ill be getting the same tent I had in my previous car.

as long as you have glass, you have greenhouse effect. unavoidable, really.
