What Is Window Film, Anyway?

Returning to your car on a hot summer day, arms full of groceries, you pause for a minute. It’s going to be SO hot in that car. In fact, you’ll probably burn yourself on the seatbelt. AGAIN.

Most of us have experience with cars that have been baking in the sun. You’ve probably considered having someone install some tint, like you’ve been seeing ads for online. But what does that even mean? What IS automotive window film?

In an article from Car and Driver , by Matthew Askari, they explain that manufacturers of automotive tint use nanotechnology with many layers of optical polyester film stacked together and applied to an adhesive layer that is thinner than a piece of paper. Pretty neat, huh?

This article also states, “While the standard glass used in car windows can block some UV radiation, a car window tint of good quality from a reputable manufacturer- if applied correctly- can help increase protection from ultraviolet radiation. It can also help preserve the interior of your car, including the upholstery, carpeting, and dashboard, which can fade over time by exposure to sunlight.”

Ok, so that’s the technical part. What about the looks part? Automotive Window Film is made by many different manufacturers, in many different shades. A shade is how much visible light is transmitted through the film. You’ve got 5%, which is like what a limousine has, all the way to 90%, which is almost clear. But please familiarize yourself with the tint laws for your state. No matter the shade, you can get up to 99% UV protection, and a range of different amounts of heat rejection.

Yes, heat rejection. There’s even more to this window tint thing! In an article by Window Film Pros they say, “By blocking a substantial percentage of the sun’s rays, window tint helps keep your car’s interior cooler, especially during scorching summer days.”

“This translates into a more comfortable driving environment for you and your passengers. Additionally, it can reduce the strain on your car’s air conditioning system, potentially leading to improved fuel efficiency.”

With a wide variety of window film options available, choosing the right type for your specific needs is important. Consider factors such as the amount of heat you want to reduce, the level of privacy you desire, and your aesthetic preferences. Consulting with an automotive window film professional can help you navigate the different options and ensure you select the film that best suits your requirements.

Automotive window film offers a transparent solution for a variety of needs, providing benefits for vehicle owners. From reducing heat and UV damage to enhancing privacy and security, it can significantly improve the comfort, safety, and aesthetics of your vehicle. So next time you're looking for ways to enhance your home or car's environment, consider the potential of window film.

All of this information is a lot to digest. Luckily, there are lots of resources out there to help you when it comes time to choose a tint for your vehicle. There is the Window Film Pros website, or just reach out to us! We are a professional shop that is happy to walk you through the process.
