When summer hits, the heat inside your car can quickly become unbearable—even in moderate temperatures. Research shows that the interior of a parked car can soar past 100°F within an hour. That’s precisely why you need to know about the best car window tint for heat reduction. 

“The right car window tint can make all the difference by blocking harmful UV rays, reducing interior heat, and preserving your upholstery from sun damage. Plus, a good window tint helps your AC work more efficiently,” said Mobile Tinter Steven Radja.

In this blog post, we’ll cover the types of window tint you can choose from as well as provide an overview of how to identify which car window tint type will keep you cool; what to keep in mind when selecting your tint, and how to maximize the performance of your window tint.


Types of Window Tint You Can Choose From

Depending on your budget and how you want your car to look, you have several options for getting the best window tint for heat reduction inside your vehicle.

Carbon Window Tints

With a matte finish, carbon tints block up to 40% of infrared rays, reducing heat and preventing upholstery from fading. They are durable, providing year-round insulation, but may cause glare and haze.

Ceramic Window Tints

Known for their high heat resistance, ceramic tints block up to 50% of solar heat and 99% of UV rays. They offer excellent protection without affecting radio or cell signals and don’t interfere with visibility, making them a top choice for those looking to keep their vehicle cool and protected.

Crystalline Window Tints

If you’re looking for the best heat rejection window tint without a dark appearance, crystalline tints block up to 60% of heat and 99% of UV rays. They allow maximum visibility while still providing high-level sun protection.

Dyed Window Tints

Economical but less effective at reducing heat, dyed tints provide privacy and UV protection but fade more easily over time. They are best for those seeking a basic, budget-friendly solution.

Hybrid Window Tints

Combining dyed and metalized film, hybrid tints offer balanced protection from heat and UV rays without excessive reflection or glare.

Metalized Window Tints

These tints use metallic particles to reflect heat and block glare. While they provide solid heat rejection and privacy, they may interfere with cell phone signals.

What to Consider When Choosing a Car Window Tint That Blocks Heat

Here’s what to keep in mind when choosing a car window tint:

  • Price: Establish a budget to narrow down your choices. Higher-end tints like ceramic or carbon typically cost more but offer better performance.
  • Quality: Opt for carbon or ceramic tints, which resist fading and provide better scratch resistance.
  • Legality: Ensure that your chosen tint complies with local laws regarding darkness, reflectivity, and placement on your vehicle.
  • Total Solar Energy Rejection (TSER): Look for a high TSER rating to maximize heat dispersion and keep your vehicle cool. (TSER is a measurement of how much solar energy a window tint can keep out.)
  • Visible Light Transmission (VLT): A higher percentage of VLT means more light passes through the tint. Choose a VLT percentage that balances heat reduction with visibility—darker tints block more light but can impact nighttime driving.
Tip

If you’re considering getting window tinting in Illinois, it’s important to follow specific rules based on the type of vehicle you drive.

For sedans, only the top 6 inches of the windshield can have non-reflective tint. The front and back side windows, along with the rear window, must all allow more than 35% of light to pass through.

For SUVs and vans, the rules are more relaxed for rear windows. The windshield still follows the same 6-inch non-reflective limit, and the front side windows must allow more than 35% of light. However, the back side and rear windows can have any darkness level.

How to Maximize Tint Performance in Reducing Heat

To maximize heat reduction with car window tint, consider the following points:

1. Invest in Premium Window Tint

Opt for high-quality films like ceramic or carbon with high TSER. These tints block more heat, keeping your vehicle cooler while enhancing UV protection and reducing glare. While ceramic tints are pricier, they offer the highest level of heat rejection and durability, making them a worthwhile investment for both comfort and protection. 

2. Professional Installation is Key

Skilled installation prevents bubbles or imperfections, ensuring that the tint properly adheres to the glass and maximizes heat rejection. Proper installation also eliminates the risk of bubbles, wrinkles, or gaps that could compromise heat rejection and overall aesthetics. Plus, poorly installed tint may not adhere properly.

3. Maintain Cleanliness

Regularly clean your car windows using a non-abrasive cleaner and a soft microfiber cloth. Dirt, dust, and debris can accumulate on the surface, potentially reducing the effectiveness of your tint.

Pay particular attention to the edges and corners where dirt tends to build up. Keeping your windows clean will help you enjoy cooler interiors and clearer visibility.

4. Allow Adequate Cure Time

After your tint is applied, it needs proper time to cure. Rushing the process or rolling down windows too soon can cause peeling or bubbling.

Following manufacturer instructions and waiting the recommended time ensures that the tint bonds correctly to the glass, preserving its integrity. Patience during this phase guarantees long-lasting results and a cooler, more comfortable ride.
