Do car windows have UV protection

Do car windows have UV protection? This is a question that has been asked by many car owners who are concerned about their exposure to harmful ultraviolet (UV) rays while driving.

UV rays can cause damage to our skin and eyes, and prolonged exposure can even lead to skin cancer.

When it comes to car windows, the answer is not straightforward. While some car windows do have a certain level of UV protection, not all of them do.

The level of protection depends on the type of glass used and any additional coatings or tints applied to the glass.

For example, some car manufacturers use laminated glass for the windshield, which provides some degree of protection against UV rays.

However, the side and rear windows may be made of tempered glass, which provides no UV protection.

However, it’s important to note that not all window tints or films provide the same level of protection, and some may even interfere with visibility while driving.

In this guide on Do car windows have UV protection, you will explore the various aspects of how car windows protect against UV radiation.

Understanding UV Radiation

UV radiation is a type of electromagnetic radiation produced by the sun. UVA and UVB are the types of UV radiation that can cause skin damage and increase the risk of skin cancer.

UV radiation is present all year round, even on cloudy days, and can penetrate through clouds and glass. 

UVA can penetrate deep into the skin and cause premature aging, while UVB is responsible for sunburns and skin cancer. It is important to protect your skin from both types of UV radiation.

The Role of Car Windows

Car windows are designed to provide protection from the sun’s rays, but not all car windows offer the same level of protection. 

The type of glass, its thickness, and the angle at which it is installed can all affect how much UV radiation is blocked.

The most common type of glass used in car windows is tempered glass, which is designed to shatter into small pieces if it breaks. 

Tempered glass can block most UVB radiation, but it does not offer much protection from UVA radiation.

Another type of glass used in car windows is laminated glass, which is made by sandwiching a layer of plastic between two sheets of glass. Laminated glass can block both UVA and UVB radiation, but the amount of protection depends on the thickness of the glass and the type of plastic used.

3 types of UV rays: 

UVA, UVB, and UVC. While UVC rays are absorbed by the Earth’s atmosphere and do not pose a risk, UVA and UVB rays can cause damage to your skin and eyes.

How can UV rays harm you?

Exposure to UV rays can have numerous negative effects on your health. Short-term effects can include sunburn, while long-term effects can include premature aging, wrinkles, and skin cancer. 

In addition, UV rays can also damage your eyes, leading to cataracts and other eye diseases.

How Do Car Windows Block UV Rays?

Car windows are typically made of tempered or laminated glass that can reduce UV transmission to varying degrees. Tempered glass is heated and cooled rapidly to make it stronger and more resistant to impacts.

It is commonly used for side and rear windows, which are not subject to as much stress as the windshield. Tempered glass can block up to 97% of UVB radiation, but only about 40% of UVA radiation.

Laminated glass, on the other hand, consists of two or more layers of glass with a layer of plastic film in between. 

It is the type of glass used for windshields, which needs to withstand high impacts and prevent shattering. Laminated glass can block up to 99% of both UVA and UVB radiation, depending on the thickness of the film.

How Effective is UV Protection from Car Windows || 4 Steps Explained 

While car windows can block some UV radiation, their effectiveness depends on various factors, such as:

  1. The type and thickness of the glass: as mentioned earlier, laminated glass provides better UV protection than tempered glass, but also depends on the quality of the film and the number of layers.
  1. The angle and orientation of the sunlight: UV radiation can penetrate through car windows at different angles and intensities, depending on the position of the sun and the time of day.
  1. The level of tinting or coating: some car windows may have additional layers of tinting or coating that can further reduce UV transmission. However, these may also affect visibility and legality, depending on local laws and regulations.
  1. Therefore, it is difficult to give a definitive answer to how much UV protection your car windows can offer. 

However, experts generally agree that car windows may not provide adequate protection against prolonged exposure to sunlight, especially if you have fair skin, sensitive eyes, or a history of skin cancer.

What Can You Do to Enhance UV Protection in Your Car? || 3 Steps Formula 

Here are some tips that can help you reduce UV exposure while driving:

Use sunscreen:

Applying sunscreen with a high SPF (30 or above) can help protect your skin from UV radiation, even if you are inside the car. Make sure to reapply every few hours, especially if you sweat or get wet.

Wear protective clothing:

Wearing long sleeves, pants, and a hat can also shield your skin from UV radiation. Choose light and breathable fabrics that can wick away sweat and keep you cool.

Use UV-blocking window film:

 If you want to enhance your car’s UV protection without sacrificing visibility or appearance, you can consider using window film that can block up to 99% of UV radiation. 

However, make sure to choose a reputable brand and have it installed by a professional to avoid air bubbles or wrinkles.

The Importance of Window Tinting

Window tinting can provide additional protection from UV radiation by blocking up to 99% of UVA and UVB radiation. The level of protection offered by window tinting depends on the type of tint used, the darkness of the tint, and the quality of the installation.

It is important to note that different states and countries have different laws regarding the darkness of window tinting, so be sure to check your local regulations before getting your windows tinted.

How can car window tinting protect you from UV rays?

Car window tinting can provide protection against harmful UV rays by blocking up to 99% of UVA and UVB rays. 

This means that you and your passengers are less likely to experience the negative effects of UV exposure, such as sunburn and skin cancer.

In addition to protecting your health, car window tinting can also protect your vehicle’s interior. Prolonged exposure to UV rays can cause your car’s upholstery, dashboard, and other interior surfaces to fade and crack over time

With window tinting, you can prevent this damage and keep your car looking newer for longer.


1. How to remove window tint?

One common method to remove window tint is using a steamer to soften the adhesive and then carefully peeling the tint off. 

Another method involves using a solution of soapy water and ammonia to loosen the adhesive, followed by scraping the tint off with a razor blade. 

A professional tint removal service is also an option.

Final Thoughts 

In conclusion, it is important to consider the level of UV protection provided by car windows. 

Additionally, regular maintenance and replacement of your car’s windows can also help ensure that they are providing adequate protection. 

It is important to note that while most modern cars have windows that provide some degree of UV protection, older or lower-end vehicles may not have this feature. 

Additionally, certain types of vehicles such as convertibles with soft tops or cars with large sunroofs may not be able to fully control UV rays, putting passengers at a higher risk of UV exposure. 

As we’ve explored in this guide do car windows have UV protection, it is always recommended to wear sunscreen and protective clothing, even when inside a car.
