Are Tesla Windows UV Protected? (Benefits)

The effects of UV radiation on your car as well as on your health cannot be underestimated. UV rays can damage both the interior and exterior of your car and at the same time cause serious health issues.

For this reason, it is not surprising that big automakers such as Tesla are introducing some form of UV protection with their latest models. This leads us to the big question – are Tesla windows UV protected? Let’s find out.

Are Tesla Windows UV Protected?

Yes. Tesla windows are UV protected. However, this only applies to the latest models since older car models do not have adequate UV protection. The latest Tesla car models like the Model 3 and the Model S have two glass panels on all of their windows. 

The glass panels used on Tesla vehicle models are more than just any other ordinary car glass. They have a UV-reflective layer that repels rays from the sun, thus reducing radiation and the greenhouse effect.

This goes a long way to protect the interior of your car from heating up while protecting your skin from the effects of direct exposure to the sun.

The law requires that all windshields, regardless of the vehicle make or model, must be made from laminated glass and it should contain a layer of stretchy plastic between two layers of glass for safety purposes.

The glass can break easily in case of an accident but the stretchy plastic absorbs the impact. 

Tesla goes a step further to ensure that their windshield is not only safe but UV-protected.

The stretchy plastic between the two glass layers also works by absorbing up to 98 percent of UVA and UVB rays from the sun.

Besides, the windshield of Tesla vehicles is not the only glass component to integrate UV protection. The automaker ensures that all windows, including the sunroof, rear windows, and side windows, contain UV-absorbing technology.

This guarantees maximum protection for drivers and passengers, especially during long commutes.

What are the UV protection levels of model 3?

Tesla has several UV protection levels for their cars, depending on the model. The Model 3 has two levels of protection against infrared and ultraviolet rays. Its tinted glass roof provides up to 98 percent protection against ultraviolet rays while still maintaining unparalleled views that every car owner wants. 

Unlike simple car windows, the windows of the Tesla Model 3 consist of two glass panels. The glass panels contain a reflective layer designed to repel ultraviolet rays as well as infrared radiation.

This makes a lot of difference in preventing heat buildup in enclosed spaces such as the interior of your car.

The most conspicuous aspect of this tinted sunroof is that it has a rusty orange color. However, the orange color is only noticeable after splashing droplets of water on the roof. Well, the change in color is due to the refraction of UV rays through the condensed layer in the glass.

Does the glass on windows block UV rays?

Yes. The glass on windows is designed to block UV rays, but only to a certain percentage. Some types of glass can prevent as much as 98 percent while other types are weak and they do not provide much protection.

There are three main types of UV rays, including UV-A, UV-B, and UV-C rays. UV-A rays are long-wave UV radiation that penetrates through the glass up to the dermis while UV-B rays are medium-range radiation that only reaches the epidermis.

UV-C is short-range rays that do not cause much harm. Whatever the case, you should install UV-protected glass in your car to avoid health issues and safeguard your car from the effects of excessive heat.

Most types of window glass are only able to prevent UV-B rays but they are unable to absorb UV-A rays.

The good news is that you can improve UV protection by adding films, coatings, and treatments. Enforcing these protective measures will go a long way to prevent damage caused by sunlight and infrared radiation.

How to know if your windows are UV protected?

Knowing if your windows are UV protected does not have to be hard. However, with so many different types of materials used to make windows, telling the difference can be a bit of a challenge.

Fortunately, there are several strategies you can use to tell if your windows are UV protected.

In fact, you can tell if your windows have LowE coating so you can estimate the amount of ultraviolet rays getting inside. Here are a few tips on how to go about it.

Use a lighter

For this to work, you have to wait until nighttime. When it’s dark, simply light up a match or a lighter and move it closer to your window and then pay keen attention to the reflection of the ensuing flame.

Ideally, the reflection should produce two or three flames. If you see two flames then your windows are not UV protected, but if three flames appear then your windows consist of LowE coating, meaning they are UV protected.

Look for a UV-protection label

You do not have to sweat to know if your windows are UV protected. One of the easiest ways to tell the difference is to look for a UV-protection label on your windows.

Many manufacturers usually label their UV-protected products as a way of enticing customers and building brand awareness.

Use a UV flashlight

Another fast and easy way to know if your windows are UV protected is to use a UV flashlight. Using a UV flashlight is a simple test that you can do even at home. You just need to shine the flashlight onto the windows.

No products found.

All types of windows have some fiber layers and if these fibers glow when you shine your UV flashlight then you should know that you are not UV protected.

Do all windows have UV protection?

Yes. All windows have some form of UV protection. But as you probably know, there are different varieties of UV rays meaning your windows may or may not be able to block all types of ultraviolet radiation. 

As already discussed, the three main types of UV rays include UVA, UVB, and UVC. These rays have varying wavelengths, ranging from short waves to long waves.

Your windows might have UV protection but they may not be able to prevent UVA rays. 

UVA rays have the longest wavelengths, making them harder for windows to absorb while UVB and UVC have medium and short waves, which make them easier to prevent. The ordinary glass allows up to 74.3% of UVA radiation to pass through.

This means you have to treat your windows with special coatings or films to reduce the amount of radiation passing through.

How to block UV rays on Windows?

UV radiation can cause great damage to your car seats, furniture, and your health. Taking measures to block UV rays from passing through your windows can go a long way to protect your property and your health. Here are two strategies you can use to block UV rays:

  1. Deflection

Deflection is a strategy that involves diverting the UV rays from the surface of the glass or window to the atmosphere. The rays bounce off the surface of glass thus protecting you from harm.

One of the best ways to deflect UV rays is to treat your windows with films. These films help block up to 99 percent of UV-A and UV-B rays as well as infrared radiation through deflection.

  1. Absorption

Another strategy of blocking UV rays is through absorption. Instead of deflecting the rays, the glass traps the radiation thus protecting the interior of your car from sun damage.

An excellent option for absorption is by installing Low-E glass coating, which is a thin transparent layer that allows light but blocks UV radiation.

Another way to block UV radiation is by replacing your window screens with LowE glass. You can also install curtains or blinds, but this won’t provide 100% protection from UV rays.

Can UV pass through curtains?

No. UV rays cannot pass through curtains or drapes as long as they remain closed. It does not matter whether the curtains are thick or thin, UV rays cannot pass through solid materials like drapes or curtains.

The only downside is that the UV rays will discolor your curtains or cause them to fade. You may need to replace your curtains after several weeks due to discoloration.

Final thoughts

The reason why it is important to know if your windows are UV protected is that any excessive exposure to sunlight can cause a lot of damage to your car seats, property, or even your skin. In fact, doctors attribute exposure to UV rays as one of the main causes of skin cancer. Knowing if your windows are UV protected can go a long way to safeguard your car and your health.

The good news is that newer Tesla car models such as Model S and Model 3 come with UV-protected windows. With protection against UV radiation, you can enjoy longer commutes without worrying about heat buildup in your car or any health concerns related to your skin.
