You need the best car window tint for heat reduction if your goal is to make the car cooler, and you don’t really care about looks.

Besides, the general purpose of tint on your window or windshield is to reduce heat in the car interior by blocking up to 99% of harmful ultraviolet rays from entering through the glass—Winter Park Tint & Paint Protection.

Window tint types available in the market

There are about 6 common window tints out there. And you’re supposed to make a pick depending on your needs.

a. Metalized

Metalized window tints can reduce heat by reflecting it away from the vehicle. It uses tiny (and almost invisible) metallic particles and is embedded in the film. However, they tend to affect radio signals.

The reflection gets rid of UV rays and also reduces glare, protecting your windshield and window from possible fade and crack. Metalized window tints are also considered to give a higher shatter and scratch resistance to the glass.

b. Dyed tints

This type of window tint is made of multiple dye layers designed to block sun rays. The purpose of the dye is to absorb solar heat, thus preventing a reasonable portion of heat from entering your car.

Unfortunately, dyed window tints do not offer the same level of protection, compared to other tint types.

Dyed tints also provide privacy as they are available in an opaque appearance. They tend to fade quickly over time though.

c. Hybrid tints

Hybrid tints are a combo of dyes and metallic particles and don’t result in an overly dark glass. This tint doesn’t also tend to be mirror-like or reflective.

If you’re looking for privacy and heat reduction altogether, you want a hybrid tint for your window and windshield.

d. Crystalline tints

If you don’t have “dark” in mind, get crystalline tints. You almost won’t notice that your glasses have a tint with this option, and they still prevent harmful sun rays.

e. Ceramic tints

Ceramic window tints are often pricier and come with high-quality materials. They contain l nonconductive ceramic properties capable of blocking up to half of the solar heat and up to 99 percent of harmful UV rays. Ceramic tints won’t affect your cell phone or radio or cell phone signals like metallic tints would.

f. Carbon tint

Carbon tints come with a distinctive matte finish that adds to your vehicle’s appearance. It contains carbon and can block harmful infrared rays by up to 40%, preventing your car interior and upholstery from getting hot or fading.

During winter, it makes the interior feel warmer and you save energy with the help of its insulation. The upside is that carbon tint tends to be durable, compared to others.

What to look for when buying window tint

We already understand that you need your window tint primarily for heat reduction. In this case, you’re looking at a window tint with higher TSER (Total Solar Energy Rejected) for better heat reduction. However, before you pay out the money, consider the following too:

1. Your local laws

Your state laws can be a major factor, so look out for the regulations. You want to know the tint percentage acceptable in your state to avoid potential fines or even risk an impound.

2. Harmful rays blockage

The tint you invest in should be able to guarantee even up to 99% ability to block the sun’s harmful UV rays. Not only will the sun affect your vision and driving experience, but it can also cause your car interior to degrade faster due to cracks and fades.

3. Visible Light Transmission (VLT%)

VLT% is a measurement for an automotive window tint. It represents the percentage of visible light that gets through either the film (film VLT%) or window plus film net VLT%. A lower VLT% usually has a darker tint.

4. Custom fit or rolled

A custom-fit is the window tints already pre-cut for your specific vehicle. However, you may also find inconsistencies in this type of window tint.

On the other hand, the rolled tints are not pre-cut, so you have to the cutting and fit them yourself. However, this can be stressful, especially if you don’t have the tools and experience.
