Window Tint Terminologies You Should Learn [Infographic]

Window tinting offers many benefits for vehicles: it can increase the car’s aesthetic appearance, improve its fuel efficiency, and protect its interior upholstery. In addition, it also provides advantages to car owners. Installing tint films on the vehicle’s glass windows offers drivers and passengers an added layer of protection against the sun’s glare and harsh ultraviolet radiation.

Investing in car window tint films provides a great return on investment. Apart from the abovementioned benefits, window tinting can also save car owners money in the long run.

If you want to invest in window tint films for your car, you need to understand more about window tints. Aside from learning the different types of window tint films available in the market, you also have to get yourself familiar with window tint terminologies that are used in the industry.

Here are some of the window tint terms you should know:

Visible Light Transmittance

Visible light transmittance (VLT) is the amount of visible light passing through a window. Generally, the lower the VLT percentage, the less visible light passes through the window. Thereby, the more tinted the glass is, the lower the VLT percentage it has.

VLT is classified into two: Internal and External Visible Light Transmittance. Internal VLT refers to light that passes through a window from inside the car. On the other hand, External VLT refers to light passing through a window from the outside.

Visible Light Reflectance

In contrast with VLT, visible light reflectance (VLR) is the percentage of light reflected by the glass window. The lower the VLR percentage, the lesser light is reflected. Non-tinted car window reflects only about 8 to 10% of visible light.

In window films, the VLR determines the film’s capability to reduce glare. The higher the VLR percentage of a window film, the better glare control it offers.

U-Value

U-Value, also known as U-Factor, is the window tint’s ability to transfer heat between the inside and outside of a car. Generally, the lower the U-value of a window tint, the better the tint film and window will insulate. This also means lesser energy is needed to maintain the vehicle’s interior temperature and keep it cool and comfortable.

Shading Coefficient

Shading coefficient is the ratio of heat that passes through a window with window film to the heat that would pass through un-filmed glass. Naturally, window tint films with lower shading coefficient values have better shading capabilities.

Solar Heat Gain Coefficient

Solar heat gain coefficient (SHGC) is similar to the shading coefficient; the only difference is that SHGC measures the energy re-radiated back into the vehicle’s interior due to the glass heating up and increased heat absorption.

Window tint films with lower SHGC values generally have better solar control properties.

Total Solar Energy Rejected

Total solar energy rejected (TSER) refers to the amount of solar energy (heat) reflected off the window, which means the energy is prevented from coming into the vehicle. The higher the TSER of a window tint film, the better it can block and reject heat.

Curing Time

The curing time is the length of time it takes for the window tint’s adhesive to fully bond and sticks to the car’s glass window. In ideal weather conditions, the curing period of window films typically takes up to three days.

When window tint films are freshly applied on your vehicle’s glass window and they are not fully dry yet, you may be advised to avoid rolling down your window or tampering with your tints.
