Window tint is a thin film that is applied to the windows of a car, home, or building. It is made of a polyester material that is coated with a metal or ceramic layer. The purpose of window tint is to block out some of the light that comes through the windows, which can help to reduce glare, heat, and UV radiation.

There are many reasons why people choose to tint their windows. One of the main reasons is to reduce glare, which can make it difficult to see while driving or working on a computer. Tinted windows can also help to reduce heat, which can make a car or building more comfortable to be in during hot weather. In addition, window tint can block out harmful UV radiation, which can cause skin damage and fade furniture and carpets.

Overall, window tint is an important feature that can improve the comfort and security of a car, home, or building. In the following chapters, we will explore the various ways in which window tint is measured and the factors that can impact its performance. 

Tint Percentage

Tint percentage refers to the amount of light that is blocked by window tint. It is usually expressed as a percentage, with a higher percentage indicating a darker tint. For example, a tint with a 50% tint percentage would block 50% of the light that passes through the window.

There are a few different levels of tint percentage that are commonly used. The most common levels are 20%, 35%, and 50%. These percentages are often used as legal limits for window tint in different states. Some states have stricter laws, requiring a lower tint percentage, while others may allow for a higher percentage. It is important to check the laws in your state to determine what level of tint percentage is legal.

In addition to legal limits, the choice of tint percentage will depend on the specific needs and preferences of the user. A darker tint may offer more privacy and UV protection, but it can also make it harder to see out of the window. A lighter tint may offer less privacy and UV protection, but it can also make it easier to see out of the window.

There are a few different ways to measure tint percentage. One method is to use a tint meter, which is a device specifically designed to measure the amount of light that is blocked by window tint. These devices work by shining a light onto the window and measuring the amount of light that passes through.

Another way to measure tint percentage is to use a spectrophotometer. This is a more advanced instrument that can measure the amount of light absorbed and reflected by a window film. It works by shining a light onto the window and measuring the intensity of the light that is reflected back.

Mainly there are two types of tint percentage measured. These are Visual Light Transmission (VLT) and Visual Light Reflection (VLR). Let’s explore more about these.

Measuring Visual Light Transmission (VLT)

VLT refers to the amount of visible light that is able to pass through a window film and reach the inside of a vehicle or building. It is usually expressed as a percentage, with higher numbers indicating a higher amount of visible light transmitted and lower numbers indicating less visible light transmitted.

There are different levels of VLT available, ranging from very light films with high VLT (80% or higher) to very dark films with low VLT (5% or lower). The appropriate VLT will depend on the specific needs and preferences of the user. For example, a driver who wants to reduce glare and heat inside their vehicle may choose a window film with a lower VLT, while someone who wants to maintain a clear view of the outside may choose a film with a higher VLT.

One way to measure VLT is by using a spectrophotometer, which is a device that measures the intensity of light as it passes through a sample. The spectrophotometer is used to measure the amount of light that is transmitted through the window film and the amount that is reflected or absorbed. The VLT is then calculated by dividing the amount of transmitted light by the total amount of light that hits the window film and multiplying by 100%.

It is important to note that VLT is only one factor to consider when choosing window film. Other factors such as reflection and absorption, the type of film used, the color of the film, and the quality and thickness of the film can also affect the performance of the window tint.

Measuring Reflection and Absorption (VLR)

In addition to visual light transmission (VLT), the reflection and absorption of light by window film is also an important factor to consider when measuring window tint.

Visual Light Reflection (VLR) refers to the percentage of light that is reflected back off the surface of the window film. A higher percentage of reflection can help to reduce glare and heat inside a vehicle or building, but it can also affect visibility by making it harder to see through the windows from the outside.

Absorption refers to the percentage of light that is absorbed by the window film. Absorption can help to reduce the amount of heat and UV radiation that enters a vehicle or building, but it can also affect the appearance of the windows from the outside.

To measure the reflection and absorption of window film, a spectrophotometer can be used. This device measures the intensity of light as it passes through a sample and can be used to determine the percentage of light that is reflected, absorbed, or transmitted through the window film.

The reflection and absorption of window film can vary depending on the type of film used, the color of the film, and the quality and thickness of the film. It is important to consider these factors when choosing window film to ensure that it performs to your specific needs and preferences.

In summary, reflection and absorption are important factors to consider when measuring window tint, along with VLT and tint percentage. The right combination of these factors will depend on the specific needs and preferences of the user.

Where Can I Get My Window Tint Measured?

There are a few different options for getting your window tint measured. Here are a few possibilities:

Automotive tinting shops: Many automotive tinting shops offer window tint measurement services as part of their services. You can bring your vehicle to a local tint shop and have the tint measured by a professional. This is the best option of all.
