You don’t need to be a Mafia don or Hollywood star just in order to do a window-tinting job on your car. Everyone can equip this feature to keep privacy in car.
Besides that, there are a number of other perks of it that you’ll surely appreciate. It provides protection from sunlight and UV rays, enhances the visual beauty of your car and so on.
But have you ever wondered how does this little wonder works? Or what are the actual mechanism that lets you enjoy the privacy even on the go?
In this post, we’ll figure that out.
What Is Car Tint Windows Made of?
Let’s start from the very basic- the material.
Window tilts are nothing but highly engineered stickers that are made of strong polyester laminate. What creates the tinting effects in this glasses is called tinting agent. Tinting agents are distributed as a thin layer right inside the glass.
There are two sides of the glass and both have got some roles to play.
At one side of the window, there are adhesives to stay bonded with the window. While on the other side, there are scratch-resistant coatings. It protects the window glass from external damages.
The scratch-resistant coating also helps to prevent the buildup of containment on the glass itself.
These features and their benefits vary from model to model. Also, the price has a good role to play in this case. But mostly, the basics are the same.
How Window Tinting Works so Good?
Since invention, people took tilting windows as a serious addon to the cars. But what are the actual reasons? What makes this simple layer of chemicals to do the magic?
Here is the catch-
In case of non-tilted window glass, almost 90 percent of the sunlight directly enters into the car. 5% of the light is reflected and the last 5% is completely wasted.
When window tintings are appointed to reduce this figure, we’ve got a firm control over how much exact sunshine we want to let in. It blocks the way of a specific portion of the light beams.
The Design of Window Tint
Window tint is a strong polyester laminate which is treated in a number of ways that can improve the performance and look. The layer is made up with a bulk of tints. The achieve the actual performance characteristics, an extra layer is also made up with tinting agents. These tinting agents are usually metals and dyes.
Once this clear polyester is made, there is another thin layer of film applied on it. This one is made of some other kind of tinting agents. It depends on what exact kind of tinting effect you’re looking for among dye, metal or ceramic.
How the Tinting Effect Works
Now, what exactly makes the beautiful tinting effects work? Here we disclose the fact-
There are many types of tinting films. But in the usual sense, all of them are supposed to do four kinds of works-
- Radiation.
- Reflection.
- Absorption.
- Transmittance.
Radiation: Radiation prevention is one of the sole benefits that we receive for window tints. Specially, in winter and summer, the car tint is supposed to play the role of heat insulation in between the space of inside and outside the car.
This helps us in both ways. In winter, it keeps the heat of car inside the car compartment. And in summer, it won’t let outsider heat waves enter into the car.
Thus, it keeps the riders and passengers comfortable.
Reflection: This is another primary work on a glass tint. It keeps away the significant portion of sunlight that may contain dangerous visible and ultraviolet rays. The reason behind is, tint layers have something called the sputter coating which is made out of metal particles.
Absorption: The absorption part is more like a health benefit of car tints. When sun rays fall upon it, it absorbs certain portions of it and doesn’t let in to enter into the car compartment. Also, this reduces the amount of visible light and provide the desired darkness the user wants.
Transmittance: Finally, the last job of car window tints is to transmit a certain amount of light into the car interior. This depends on the percentage of light it’s allowed to transmit by its chemical structure.
The Science Behind the Car Window Tint Effects
As you’ve just seen, car window tint performs four types of actions to keep you safe and sound inside the car. But what’s the actual science behind that?
We will tell you that now.
The polyester based film that’s used in building window tint, allows only a number of types of light rays to go through it. Rest of the lights are absorbed or reflected away.
And this power of tints can be varied by variating the number of dyes and metals used to prepare the tint.
Another fact is, these tints don’t impede the visibility in the darkness as the sunglasses do.
The reason behind is, technicians add a laminated film from inside the car’s window or windshield. For that, the amount of light traveling from outside of the car is reduced. While the light traveling from inside the car isn’t affected at all.
So you’ll have a clearly visible view of outside whenever you’re inside the car. This also explains why many people’s thoughts on ‘driving car are dangerous at night if it has a window tint’- is wrong.

Another serious perk you receive through tinting windows is- it filters out the bad part of the sunlight. Also, it cuts down the glare of sunlight and makes driving easier.

- Back Side Windows: In back side windows, any kind of darkness level can be used.
- Rear Window: Any kind of darkness can be implemented.
Window Tinting Laws in SUVs and Vans
- Windshield: The windshield should be of the non-reflective type as long as they’re longer than 4 inches. Reflective windshields up to 4 inches are allowed.

- Back Side Window: In back windows, any kind of darkness can be used.

Frequently Asked Questions(FAQ)
To end up the discussion, here we go answering some of the commonly asked questions-
Question: Does window tint affect on me while I’m driving at night?
