Does Dark Tint Equal More Heat Rejection?

A common question tint companies receive daily is “how dark will my window tint need to be to block out heat”? There are many layers to understand to answer this question. To start, there are three main components to heat: Ultraviolet rays (UV), infrared heat (IR), and visible light that you can see with the naked eye. Window films are designed to block either some or all of each of those, reducing the heat that comes into your home or vehicle. 

More traditional films will have darker shades with higher heat rejection. These films will only block the UV and visible light to reduce the heat coming in. Dyes are also added to the film during production to block more light and give a darker appearance. You can get really good heat rejection with these classic films; they are reliable and have been on the market for years. 

However, as technology grows, we see more and more films hit the market that offer much more variety to your options. These new films for starters, come with an additional layer of an IR-blocking coat. With this new coating built into them, the films can now block more than just UV rays and visible light, but IR. This not only allows for better heat protection but it also allows you to get films that aren’t as dark. 

These newer films can come in the traditional darker shades as well as virtually clear films that will block just as much if not more as the traditional films. An IR-coated film, a standard 35 shade of film will gain you an additional 10-20% overall heat-blocking rating compared to a good quality traditional film of a similar shade. This means you can maintain your aesthetic while gaining more protection. 

Clear films are usually used by car enthusiasts who want to preserve their vehicle’s aesthetic while protecting the interior from heat and UV damage.
