Dark Tint = Good Tint?

On this topic, a common misconception is that a darker tint equates to a better tint. While for some cases it might be true, we will have to look into more details.


Basically, a good tint provides a good protection against heat to the people inside the car.


This is the main objective of doing a tint. Other added features such as privacy and security are secondary although they are important as well.

First we have to understand that the heat rays from the sun come in 3 different kinds of radiation.


Infrared, Visible Light and Ultraviolet Light. All these 3 contribute heat through the windows of the glass.


With darker tint, you are able to reduce the visible light portion of the heat which is why it is true that if we compare the same tint (same series and grade), the darkest tint will offer better protection against the heat.

Next, the other two sources of heat play a role as well.


While ultraviolet heat is not as significant, most tints around can protect against ultraviolet rays easily so this is not a concern.


However, for infrared radiation, they are invisible rays that cannot be seen by naked eye.


A good quality tint is manufactured with the properties that are able to reject Infrared radiation. By rejecting more infrared, you are rejecting more heat as well.


Do take note that higher infrared rejection does not mean the tint is darker.


You can have a tint that blocks out 50% of visible light (50% dark tint) and have either good or poor infrared protection.

So when we are choosing a good tint, we will have to look at both these factors, the infrared and the visible light.


A top grade tint can be JPJ compliant (in terms of darkness) and still be able to reject lots of heat from the car whereas the lowest grade tint, which offers low protection against infrared can be hot despite you not being able to look directly inside (high darkness).
