Does Window Tinting Help With Texas Heat?

Understanding How Tinted Windows Help Keep Cars Cooler

One question many homeowners have is whether or not window tint can keep their cars cooler. As it turns out, tinting the windows of a home is an effective way to reduce the temperature inside. Tinted windows do more than provide privacy – they also minimize the amount of sunlight that enters, resulting in lower interior temperatures. You may find it quite impressive that window tinting can have such a profound effect on the temperature inside a car when you consider how thin the film is. Once you understand the scientific principles that are at play, however, it is a lot easier to understand why tinted windows do such a great job of keeping cars cool.

A Closer Look At How Window Tint Blocks Unwanted Heat

When tinted film is applied to a house’s windows, it helps block out the sun. The film that is used in the tinting process is mostly made up of polyester. With certain films, small fragments of metal and thin layers of dye are also used on the film’s topmost layer. Together, the film’s individual layers prevent solar heat gain while still letting an adequate amount of light through.

Nano-carbon ceramic films are a relatively new introduction to the window tinting industry. These window films use a combination of carbon and ceramic particles to create a film with greater heat-blocking capabilities and richer coloring. Even though films that incorporate nano-carbon ceramic technology are superior at blocking out heat, they provide excellent visibility in a wide range of outdoor lighting scenarios. Thanks to its superior ability to retain its color, this film also lasts for many years before needing to be replaced.

One way to judge the effectiveness of a specific window tint is by looking at its rating for light transmittance. This measurement, which is determined by the transmission level of visible light through the window tint, is expressed as the VLT%. The tint’s ability to absorb light, on the other hand, is expressed as its VLA%. Finally, the measurement that is used to show the amount of light that is reflected off of the window tint is expressed as its VLR%.

Since these terms can be a little bit confusing, it is often helpful to look at an example. Imagine if you had a vehicle that didn’t have tinted windows. In this case, the windows transmit approximately 90% of the visible light. Based on this, the VLT% of the glass is 90. That same untinted glass only absorbs about 5% of the light, meaning that it’s VLA rating is five. The remaining 5% of visible light is reflected off of the surface, giving it a VLR rating of five, as well. In this case, the vast majority of visible light is allowed to get through to the inside of the vehicle. As a result, the inside of the home can get quite hot.

Is Window Tint Effective At Minimizing Heat?

Ratings for light transmittance are only used to indicate the percentage of light that is blocked by the window tint. They don’t provide any real information about the cooling level that the windows provide. When you look at the research, however, there are a lot of studies that have been done that answer the question of whether or not window tint has an effect on heat. For instance, F.M. Nasir and M.A. Jasni conducted a study in 2012. This study showed that tinted windows were effective at blocking out heat.

At one point in the study, the research seemed to indicate that sunshades did a better job of blocking out heat than tinted windows. As it turns out, however, the cooling characteristics provided by sunshades only affected the region near the windows in question. When used in a home without tinted windows, sunshades only lowered the temperature inside the vehicle by approximately 2°C. By way of comparison, adding tinted windows to a vehicle lowered the temperature throughout the vehicle by as much as 8°C.

The scientific research provided by Nasir and Jasni shows that window tints are effective at blocking out heat. One point worth considering, however, is that the tints used in the study were a lot weaker than many that are available, only blocking out between 65 and 85% of the infrared light. Based on that, window tints with higher infrared-blocking rates could keep the temperature inside of the vehicle even cooler. This information makes it clear that window tinting is an effective way to lower the temperature in interior spaces.

What Are The Benefits Of Minimizing Heat Inside A House?

If the temperature inside your home climbs too high, it not only poses a health risk but can also cause the inside of your vehicle to deteriorate more quickly. When you look at a house, a high percentage of the total surface is made up of windows. Windows allow both light and heat to enter the vehicle. Sunlight streaming into the home through the windows can cause the temperature inside the vehicle to rise by as much as 19° or more in 15 minutes or less. The temperature continues to rise with ongoing exposure to the sun, climbing as high as 50° higher than the temperature outside after about two hours.

If you get into a home that is extremely hot inside, it can cause problems like heatstroke and dehydration. Even though you may not experience any initial symptoms, these problems can begin when the temperature of your body reaches about 104°. Imagine how much damage could occur after being repeatedly exposed to high temperatures in your house.

For instance, if the plastic parts in your Home’s interior are exposed to high levels of heat for a long period of time, they can give off benzene gas. This gas negatively impacts human health. Not only does benzene have cancer-causing properties but it also can result in immunodeficiency problems and anemia. Problems like these can be avoided simply by opting for tinted windows on your home to keep the heat level down inside.

Are Tinted Windows A Good Choice For Blocking Heat?

Tinted windows are highly effective at blocking heat. They help keep the rays of the sun from raising the temperature inside your home. This not only makes your home more comfortable but also helps protect your health. It seems strange that manufacturers are still making Homes without tinted windows since scientific studies have shown that they are so effective at blocking heat. Even if your current home didn’t originally come with tinted windows, you can always have tint applied to take advantage of its heat-blocking benefits.
