Can I Use Home Window Tint On My Car?

The simple response to this query is no. It is a question, though, that calls for a more detailed response. Below are the reasons why home window tint (also known as home window films or flat glass tint) should not be used on your car, together with outlined differences between this tint and car window tint:

It Is Not Regulated

The main distinction between home window tints and car window tints is that the latter is strictly regulated in most states. At the same time, both have the same intended function—increasing privacy and blocking harmful UV rays and excess heat. 

Home window tints have the potential to be much darker or more reflective than car tints. They subsequently block out more light and solar energy, which naturally results in a significant increase in privacy.

However, car window tinting is governed, and depending on where you live, it is not permitted to block more than 65% of visible light. Safety is the reason for this—both your and other drivers' safety. 

Too much light-blocking makes it more challenging for you to see what is going on in front of you and around you on the road, which is worse at night or in low light.

It Does Not Shrink

Home window tint is only used on flat or plate glass. Without curves, the ability of the film material to shrink is not required. Even the slightest curves in car windows require the film to be able to shrink to ensure a proper fit. As a result, the adhesives used to attach the films vary.

The Film Has A Different Composition

While car window tint absorbs heat, home window tint reflects heat. For example, metallic compounds can be used safely to tint windows in a residential or commercial building, but they would interfere with electronic devices if used on car windows. 

While this isn't a problem in homes and buildings, car window tints are specifically made to minimize any interference with electronics in the cramped space of a car.

While it is unquestionably not a good idea to use a home window tint on car windows, you shouldn't even consider using a car tint on windows in your house or office. 

Because car window tint can shrink and absorb heat instead of reflecting it, there is a greater chance that your home or office windows will crack or break.

What Are Some Car Window Tints Available On The Market?

When you use window film from a home on your car, you might violate numerous visibility rules. Similarly, there is a high probability that the window will break if you apply car window tint on a window in your home since the film shrinks in the heat. 

It's better to use a tint created for a car, which is readily available online. Its installation is made easy through the steps mentioned above. Nonetheless, if DIY is not your thing, you can always go with a qualified window film installer to ensure a proper installation.
