The study by Jasni and Nasir produced some hard scientific evidence that window tints do work. In fact, the tint was able to cool interior air by up to 8 degrees Celsius. A car with tinted windows was able to reduce the ambient temperature in both the front and rear of the vehicle. The average sunshade on a vehicle without tint was only able to cool the interior air temperature by about 2 degrees Celsius. Later, it was determined that sunshades only provide a cooling effect for the dashboard area. Initially, the study seemed to suggest that sunshades were more effective than window tints. In this study, the participants were able to show that window tinting does play a role in blocking heat. Nasir completed an experiment for the International Conference on Mechanical, Automobile and Robotics Engineering. Luckily, a few studies have been performed to address the question “does auto window tint reduce heat?” In 2012, M.A. ![]() How Effectively Does Tinting Your Windows Reduce Heat?Īlthough light transmittance ratings show how much light will be blocked, they don’t indicate how much cooling can be expected. Therefore, you can expect that there will be almost no cooling effect. Under these conditions, most of the light will reach the interior of the vehicle. Similarly, the VLR rating will be at five. The same non-tinted glass will have a VLA rating of five, meaning only 5% absorption. This type of vehicle will transmit around 90% of visible light. To understand these terms, picture a car that does not have any tint. VLR% shows you how much light is reflected back from the surface. VLA% indicates how much light is absorbed by the tint. The term VLT% refers to how much visible light is transmitted through the tint. You can tell how effective a certain tint is by looking at its light transmittance ratings. ![]() Rayno Film will also last for years to come due to its high color retention. Despite the incredible durability of nano-carbon ceramic films, the tint allows for increased visibility in all shades of outdoor light. This state-of-the-art process combines ceramic and carbon particles to provide maximum coloring and high levels of heat rejection. Rayno Window Film, on the other hand, invented a window film with nano-carbon ceramic technology. The layers of the film help block thermal energy from the sun while allowing some light to shine through. Some films use a thin coating of colored dye and metal fragments that line the top level of the film. The film itself is primarily comprised of polyester. How Does Window Tint Keep Heat Out?Īutomotive window tint acts as a barrier between the sun and a car’s interior. However, there are perfectly logical scientific reasons why and how window tint can keep your interior cool while outside temperatures soar. The fact that a thin piece of film could help manage temperature levels seems a little astounding at first. It helps block sunrays, which lower the overall temperature of the vehicle. Window tinting is not just a way to keep other drivers from looking inside your car. The quick answer to whether window tint reduces heat: YES! ![]() Many car owners wonder whether tinting their vehicle’s windows will really help minimize the levels of interior heat.
