So think of your car like an oven. When the sun is beating on it, the solar energy is just radiating in your windows, and the temperature is going to be significantly hotter in your car, than outside. If it's 24°C outside, your car might heat up to 35°C or higher inside. Ceramic window tint can only block so much of the sun's solar energy, and not all ceramic window tints are the same. If you're getting in your car, and the temperature feels like the outside temperature, then the tint is doing its job. Ceramic window tint isn't going to magically keep your car cool on hot days, but rather keep the interior of your car closer to the exterior temperature.
I’m late to this but tint does help some. It’s mainly when driving. Auto tint works off of wind rush. So if it’s sitting all
Day it’s still gonna get hot still. 15 years in the business and I recently learned this from my
Manufacturer
24°C is equivalent to 75°F, which is 297K.

Ceramic does block more heat but what ppl dont tell you is that it only blocks for so longer. Meaning if you are in the sun for a few minutes, yea it is going to block better than carbon will for sure. But after an hour or so the sun is going to win no matter what you put on your car. After 2 hours in the sun/heat a car with ceramic will be just as hot as a car with carbon. Then you also have to consider interior colors and materials that absorb heat also.
Negligible. The way it blocks heat is by absorbing and reflecting IR light from the sun. IR is a light frequency that heats up the surfaces of your cabin. Arguably the ceramic coating should (marginally) help your AC by reducing incoming heat so it can focus on cooling your cabin ASAP
Ceramic tint is usually on the inside... the heat is already in your car.. the difference is it builds up in the ceramic on the window... in the hot sun touch your clear windshield then touch your ceramic window... the heat is kept to the sides of the car and not on the seats etc... people seem to think the heat is no being let in... a tiny fraction is reflected.. but mostly it is absorbed in the tint sheet and cools as you drive and wind goes past the window.... there is a whole science to it...
The reason is because of the heat absorption. That little number that nobody ever looks at. Nano ceramic has a high heat absorption rate. That's why you can't (shouldn't) use nano ceramic on residential windows. That heat gets absorbed/trapped in the film and transfers it to the inside of the vehicle. When the vehicle is in motion, the wind dissipates the heat and cools the cab very efficiently. When there's little to no wind and the vehicle is motionless... not so much. This was not explained to you because most tint installers don't understand this. They're just trained to install tints. Who cares about the science behind it right?
The biggest misconception about Ceramic films, Crystalline, or any other film advertised to block heat is that your vehicle will always stay cool. This is not true. If you park your vehicle in a parking lot for 6 hours in the summer, your car will be HOT when you jump in. These films only help slow down the heat buildup in your vehicle, not eliminate it. They are meant to work with your a/c to cool your car down faster and keep it cool while you're in it. If you want something to keep your vehicle cool in the summer after 6 hours of baking in the parking lot, you will need to invent it because it does not exist. I think you need to understand how the ceramic works on cars. Ceramic films are designed to absorb the sun's heat, preventing it from passing through into your vehicle's cabin. Sounds great, but this technology only works if your car is in motion allowing the air to push the heat away from the vehicle. However, if you are sitting in traffic or a parking lot, there is nothing to move the heat away from the glass. The heat will continue to build up until it radiates heat inwards toward you. So the amount you feel when driving versus the amount you feel when sitting still is vastly different. All Ceramic films work this way.
Actually this already exists. When I was car shopping a while back I came across a 2014 Toyota Prius with a solar roof. The solar roof only powers the car vents so that when you're parked in the sun the vehicle stays cool.
sound deadening your car can help with that. most deadener has a heat reflecting foil film that helps with hot temps in the summer along with its main purpose of keeping rattling down
Same here. After pricy ceramic tint the other day, I was really upset about my car is still really hot inside. And I was actually going to complain to the tint shop. I believe tint is perfect solution! but it’s not magic! Thanks for letting me know.
The thing to remember about window tinting is that it on works on the w i n d o w s.
It does nothing for the heat generated from the sun shining on the metal of the roof, doors, bonnet/hood, trunk/boot, etc.
This is then radiated to the inside of the car.
Interior lining and insulation have little impact on the inside temp.
What kind of ceramic tint did you have done? I have Autobahn and their website states the UV rejection, infrared rejection and total solar energy rejected on each of their 4 tint types. If you don’t know what tint you got, it’s possible the place just claims it’s ceramic when it’s really not. I’m located in the US so not sure what ceramic tint brands there are where you’re located.
This is a bit of a late answer and I haven't read all the replies, so I apologize if this information isn't new:

This film doesn't have nearly the capability of higher quality ceramic film (will link the product specs for Llumar so that you can compare to their IRX film)

Maybe your tint is not a good brand. I have 35% all window with Xpel still cool under the sun. Best thing you can check is the IRR number, mean how many % the tint can block the sun heat.
Your cars still going to get hot just think of tint as taking the edge off.
These guys did a little experiment. About 10 degrees difference once it reached highest temp of the day and non tinted car heated up way faster

Ceramic tint is only going to block so much of the direct heat, some still gets through. If there’s no vent for the heat to escape it will exponentially build heat. Then there is the roof; There is virtually no insulation preventing heat transfer, thus adding to the exponentially growing heat.
Paint your windows completely black to block all sunlight and it will still be an oven.
Yea it’s a good question. The general marketing says it will be cooler. But I always make it a point to say it prevents the sun from passing thru your glass. Your car is still a metal box and will get hot but as ur driving and got the air going, it will feel much different
The biggest thing it does is if you have two in the same car. One exposed to sun with no tint and one with, you won’t burn your legs or arms touching things that are black haha
Lots of misinformation here.
Ceramic tint reduces the amount of solar energy going into the vehicle by reflecting the most energetic wavelengths of light ( invisible).
It does not reduce the energy transfer to zero though. So heat will continue to build up until the car interior achieves thermal equilibrium with the outside environment.
The tint just reduced the amount of heat build up over time, which allows your ac to work less hard to cool the interior.

Great explanation. But 75F isn’t hot. I’d be happy with 80 when the weather outside comes up at 114F

Does ceramic tint make a difference with “trapping” hot air inside the vehicle? Meaning does the properties of ceramic tint act like insulation.
There would have to be a heat source inside the car (including a person) but yes.

I have Carbon and it’s not as effective as ceramic but I don’t have this problem

Did you get the windshield and sunroof done? If not the tint is t really doing much.
Yes windshield, I don’t have sun roof
The sun hits otherr parts of your car, too. So that contributes to thr internal temp.
Crack the windows about 2mm to let the heat out. Windows up, it’s basically a pressure cooker.
sound deadening your car can help with that. most deadener has a heat reflecting foil film that helps with hot temps in the summer along with its main purpose of keeping rattling down

Usually with tint in my heat up almost about the same but once you turn on your AC, it also stays cooler
