Most Important Terminology to Know When Purchasing Car Tint in the Philippines

Just like most technical products, car window tint comes with a lot of terms that are tough to understand for an average person. There are certainly a few words that we are familiar with such as light energy, heat energy, ultraviolet rays, and infrared rays. However, there are other scientific terms such as reflectance, transmittance, and absorption, that we aren’t aware of.

Understanding these terms will help you make a much more informed decision while choosing the best car tint in the Philippines. You will better understand the functions of different kinds of films. Moreover, you can easily communicate with the tint professionals to ensure the best possible installation.

Here are the terms about car window tint that you need to know:

Total solar energy

It is the whole range of the sun’s energy that reaches the earth’s surface. Total solar energy contains visible light, ultraviolet rays, and infrared rays. Window tints block all of this energy to some extent and provide comfort. Total solar energy rejected (TSER) is the percentage of the total solar energy that a tinting product is designed to keep out. A window film might reject 68% of visible light, 78% of IR rays, and 99% of UV radiation and because of this makeup, TSER becomes 81%.

Visible light transmitted

It is the amount of light that a piece of glass lets pass through. Visible light transmitted is expressed as a percentage of the total amount of visible solar energy exposed to the window. So a dark window may transmit just 5-10% of visible light into a room while a light or clear film may transmit 90% or more. Visible light reflected, on the other hand, indicates how much light bounces back to the source.

UV rejection

UV rejection indicates much of the harmful UV rays the window tint can turn away. UV rays are extremely harmful to humans as well as other living and nonliving objects. They can cause fading and increase the risk of skin cancer. They are also responsible for pre-mature aging of skin and sunburn.


It is the insulating quality of a piece of glass or film. Low emissivity film allows very little heat to pass through the material and reflects a huge amount of heat generated on the building’s interior back, retaining a desirable temperature in colder weather. When it comes to hot weather, they prevent outside heat from getting inside through the windows

U factor

It is another way to measure window film’s insulation properties. U factor indicates the heat energy level, independent of the sun’s radiant energy, which passes through the glass as well as window tint. It is calculated using a multiple of the difference between indoor and outdoor air temperatures. A low U factor points to better heat rejection inside the car in cold weather.

To sum up

We are ending this blog here with the hope that the above window tint terminologies have helped you to make a better choice of tint for your car. By learning these things we can get a deeper understanding of the functionality of such products. If you still have any more doubts or concerns, don’t hesitate to get in touch with the experts.
