This blog post reveals the facts about automotive privacy glass and why you might consider getting it added to your car.

What is Privacy Glass?

Privacy glass (also called factory tint) is a particular type of glass that is infused with dye in the factory during manufacturing. This type of auto glass is mainly used in a car’s rear windows. There is no use of window films or tints – the glass itself is dyed.

Privacy Auto Glass vs. Car Window Film

Privacy glass and auto glass film are two popular ways to improve the privacy and security of your vehicle. Both options have pros and cons, so choosing the right solution for your needs is important.

Privacy auto glass (tinted windows) is a specialized type of tinted glass that is designed to be opaque. It is often used in high-end vehicles like luxury cars and SUVs. Privacy glass is a good choice if you want to completely block out views from the outside. However, it can be more expensive than standard glass and may not be available for all vehicle models.

Automotive glass film is another option for improving privacy and security. Thin layer of tinted film can be applied to the windows of your vehicle. It can be customized to achieve the desired opacity level. Car window film is a more affordable option than privacy glass. Still, it may not provide as much of a barrier against outside views.

How Privacy Auto Glass Is Made

The electrical manufacturing process of making privacy glass is known as “deep dipping.” A sheet of glass is dipped into a vat of dark pigment or dye. The dye helps to give the privacy glass its dark tint. After that, the glass is cooled again and then cut to size.

The short answer is no, privacy glass is not illegal in cars. However, there are a few caveats to keep in mind.

First, privacy glass must meet certain tinting standards in order to be street legal.

Second, some states have additional restrictions on the use of privacy glass. For example, in California, privacy glass is only allowed on the rear windows and rear windshield of a car.

Finally, it’s important to note that even if privacy glass is legal, it can still be considered a safety hazard. If you’re considering adding privacy glass to your car, be sure to do your research and check with your local DMV before making any decisions.

There are also regulations against metallic or colored car window tint as it can distract other drivers. Therefore, check your local laws before adding privacy glass to your car.

Is Privacy Glass Worth It?

New car models now include privacy windows, except for the windshield and the front two-door windows. The windshield is kept clear for apparent reasons: improved visibility when driving, especially at night, and to assist police in identifying drivers.

Privacy auto glass offers several benefits. It blocks the sunlight with a visible light transmission rate of 22%-28%. Moreover, it also offers UV protection for vehicle inhabitants and the vehicle’s interior parts. You can read more about how auto glass protects from UV in our article about solar coated windshields.

However, it also has some drawbacks. For instance, car window tinting can make it difficult to see out of the windows, especially at night, and installing it can be pricey.

Overall, car privacy glass is a worthwhile investment for those who value privacy and want to reduce the risk of being seen by potential burglars. However, it is important to weigh the pros and cons before making a decision.

Privacy Glass Windows Cost

The cost of privacy auto glass varies greatly depending upon the type and quantity of pigment used.

The darker window tint usually cost more than the lighter pigments. The size of the windows being treated is another factor in determining cost estimation.

Generally, the price ranges from $150 (for a full tint on a smaller car) to more than $500 (for large vehicles such as a van). The prices can increase in case of customized metallic and colored automotive window tint requests.
