Window tinting has many benefits. It protects you and your car from the damaging effects of the sun, both to your vehicle and health. It can also provide security and privacy, while letting in light and letting you see out. It can even make your car more energy efficient and keep your car cool on a hot day.

With all these benefits, have you ever wondered how exactly car window tints work? How do these sheer and thin shaded films deliver the promise of better driving, comfort, privacy, and health protection?

Here is how car window tints work exactly:

At the most basic level, window tinting entails the application of tinting film onto a window glass surface. Unlike popular belief, the films are not installed on the outer surface of the glass. Instead, window tint is applied on the inside. This is done to protect the tint from external sources of wear-and-tear, including flying debris and other hard objects.

It is a sheet of strong polyester laminate treated in variety of ways to improve the look and performance of existing windows. This layer makes up the bulk of tint film, with an extra thin layer made up of tinting agents like metals and dyes added to achieve the desired performance characteristics.



I wanted to drop you an email to say how grateful I am for Kevin and all of his hard work and attention to detail when fitting the locks on my van.  Someone recently tried to break into my work van, but thanks to your work and the dead locks you fit, they weren’t able to enter and all of my tools were kept safe. 

The customer service I have received has been second to none and the dead locks you fit work brilliantly.

Thanks again






On this clear polyester film, another thin and even film is applied, made from various tinting agents. The application varies to what kind of tint is to be produced—metal, dye, or ceramic.

The second layer’s objective is to block the harmful sun rays that cause the fading and premature deterioration of the vehicle’s interiors and the car’s colours in general. It is also the layer that blocks the UV rays, both UV-A and UV-B that harms the skin to the point of causing skin cancer.

Although there are different types of window films, all of them work on the following basic principles:?
  • Reflection
  • Radiation
  • Absorption
  • Transmittance

The primary objective of the tint films is to reflect a significant portion of the harmful visible and ultraviolet rays, with something called ‘sputter coating’ (a coating of metal particles), which affects the amount of light that is rejected by the tint. More light is rejected when there is more sputter applied.

Car window tints also aim to provide heat especially during the winter. The heat is radiated through the films, keeping it from escaping. This is how tinting takes part in thermo control and gives the benefits of a warmer and more comfortable temperature while driving.

The absorption function of the tints come in a percentage of sunlight is absorbed and is prevented to be transmitted inside the vehicle. In turn, it reduces the visible light and reduce the glare from other cars. As the tints block the sunrays, it effectively cools the interior of the car, making the temperature inside much cooler and comfortable for you and your passengers.



We also offer Chameleon windscreen tinting. Chameleon tint contains coloured dyes which generate a gradient of purple, green or blue. These colours change when the vehicle is moving, or depending on the weather, lighting, or angle of view. This gives the ‘Chameleon’ effect, as the tinted windows appear to change colours depending on outdoor conditions.

Chameleon windscreen tints were originally created by the more prestigious automobile brands for looks, as well as to provide protection from the sun’s glare. Chameleon windscreen tints also provide that same sun glare protection as outlined above.
