Living in a hot climate, you know how much of a struggle it can be to enter a car that literally feels like an oven.

The good news? The right window tint can make all the difference.

Here’s how they work, which types are available and what may be best for your ideal use.

How Does Window Tint Work?

Basically, it filters out specific wavelengths of sunlight, especially ones that contribute to heat buildup. Two metrics you’ll see the most include VLT and IRR.

First, Visible Light Transmission (VLT) shows how much light shines through the window AFTER tint is applied. Second, Infrared Rejection (IRR) measures how effective your tint film is at blocking these rays. Higher values mean more effective heat rejection. While visible light may be responsible for warming up your interior, nearly half of the Sun’s energy striking Earth comes from outside of this spectrum- primarily infrared rays that we can’t see but do feel.

Types of Window Tint for Heat:

Dyed Film:

  • This tint is created when dye is added to the film during production.
  • The dye will absorb sunlight, so there’s less heat that goes into your vehicle.
  • Pros: 
    • Most affordable option
    • Does a good job reducing glare
  • Cons:
    • Doesn’t reject much heat, especially when you compare it to other types of tints.
    • Can deteriorate faster than other types of tints under intense sunlight exposure.

Metalized Film:

  • Metal particles are incorporated into this type of film which reflect light and block UV radiation from entering your car.
  • The metal is embedded in the film so it won’t interfere with radio or GPS signals.
  • Pros:
    • Due to these tiny metallic particles reflecting light, they may be more effective at keeping out heat than dyed films have been in our example above on how window tings work well against heating up cars — but still not as good as ceramic films.
  • Cons:
    • Has a shiny appearance which some people could not like

Ceramic Film:

  • This type of film is made up of ceramic particles that are both nonconductive and nonmetallic.
  • Pros:
    • Is great at blocking out heat without actually interfering with signals
  • Cons:
    • Is often one of the more expensive options but has long-term benefits

What are the Top Factors to Consider When Choosing Tint for your Windows?

Here are a few options to think about when you’re looking to get window tints living in a hot climate.

  • Level of Darkness & Visibility

Before anything else, think about just HOW dark you want your windows to look. Also add how much visibility you’d typically need at night and decide accordingly.

  • Legal Regulations

This is important. You need to check the law regulations in your area of residence. This will help make sure that the tints you end up going for are in consideration of the visibility standards of the area.

  • Budget Restraints

Again, this is important. Window tints are important but you need to make sure the choice you make doesn’t end up being unnecessarily expensive.

So decide how much money you’re actually willing to spend. A higher quality tint CAN be more expensive initially but it can save you a ton of money down the line by lowering your use of A/C.

Benefits Of Good Quality Window Tint For Hot Climates

A good quality window tint will drastically reduce the temperature in your vehicle, and keep your passengers comfortable. This means you can rely less on the air conditioner — saving fuel.

Having a professional install window tints can make or break how effective it ends up being, so visit for professional help.
