Does Auto Window Tint Reduce Heat? Let’s figure it out!
People usually have a lot of questions about window tinting and with over 10 years in the tinting business, we’re happy to answer them.
One question we’ve heard a few times around our stores is “does window tinting reduce heat?” or “how much heat can tinting block?”. That’s a great question, and the quick answer to whether window tint reduces heat: YES!
Window tinting is not just a way to keep other drivers from looking inside your car. It helps block sun rays, which lower the overall temperature of the vehicle.
The fact that a thin piece of film could help manage temperature levels seems a little astounding at first. However, there are perfectly logical scientific reasons why and how to window tint can keep your interior cool while outside temperatures soar.
To claim that Brentwood, California gets hotter in the summer could probably be one of the greatest understatements one could make about the region.
Between the intense sun and its triple-digit uncomfortable temperatures, Brentwood can effortlessly turn cars on parking lots into moving ovens. And almost every driver around the world knows that incoming heat can ruin a lot of things for them like the car’s interior.
With that in mind, they are more than willing to do anything they can to keep their cars cool. Yet despite this mindset, a lot of them still ask the question: does window tint really keep cars cooler?
Does window tint really keep cars cooler?
It may seem shocking that such a thin piece of film can lower the overall temperature of the inside of your vehicle but it does work and a window tint can keep your interior cool, regardless of how hot it gets outside. The film is mostly polyester and when several layers of this thin material are placed over windows, it will block thermal energy from the sun while allowing a little bit of light to shine through so that you experience the best of both worlds.
Many people use sun shades, however, they are not as effective because they only help cool the dashboard area and the interior will feel cooler by only a couple of degrees, whereas a car with tinted windows will see far better results and the cooling effects will apply to both the front and back of the car. This means the entire interior will feel cooler and depending on the quality of the tint, the interior temperature will drop significantly.
The higher the quality of the tint, the better results you will see but regardless of the type of tint you select, you will see a difference because they are effective in helping to reduce heat.
How Does Auto Window Tint Reduce Heat?
Automotive window tint acts as a barrier between the sun and a car’s interior.
At its most basic level, window films are made up of clear polyester film alongside an extra thin layer of agents such as metals and dyes. They are purposely created to reduce heat by rejecting the maximum amount of thermal rays that the sun produces. Its materials can block the excess heat from entering your interior while allowing enough natural light to enter your car.
How much heat do tints block? It depends on the different shades and types of tint used. While it’s true that all tint reduces interior heat, drivers should keep in mind that tint percentages vary depending on the kind of tint you pick.
The film itself is primarily comprised of polyester. Some films use a thin coating of colored dye and metal fragments that line the top level of the film. The layers of the film help block thermal energy from the sun while allowing some light to shine through.
You can tell how effective a certain tint is by looking at its light transmittance ratings. The term VLT% refers to how much visible light is transmitted through the tint. VLA% indicates how much light is absorbed by the tint. VLR% shows you how much light is reflected back from the surface.
To understand these terms, picture a car that does not have any tint. This type of vehicle will transmit around 90% of visible light. Therefore, its VLT% will be 90. The same non-tinted glass will have a VLA rating of five, meaning only 5% absorption. Similarly, the VLR rating will be at five. Under these conditions, most of the light will reach the interior of the vehicle. Therefore, you can expect that there will be almost no cooling effect.
In Summary: Does Window Tint Block Heat?
When wondering does window tint helps with heat, you can feel comfortable knowing the answer is Yes. Window tint blocks and absorbs harmful sunlight that not only makes your vehicle uncomfortable but also harms your health. Considering the research, it’s surprising that cars are still being manufactured without window tint in stock condition. If you have such a vehicle, it’s not too late to take advantage of window tinting.
