High quality automotive film is colorless and transparent. However, there are also some colored automotive films on the market. Window tint meter is an advanced instrument designed for measuring the VLT of automotive window film.

Car owners will often ask what color of the window film would be better? The deep color or the light color. Is the thermal insulation effect better for the dark automotive window film? How do I know the VLT of the automotive window film. Follow me and find the answers.

1. Is the color important for the window film?

High quality automotive film is colorless and transparent. However, there are also some colored automotive films on the market. Which type of the automotive window film is better, color or no color? The traditional dyeing film, also commonly known as "tea paper", is almost a layer of sticker with added dye. It can only block light but cannot effectively heat the film. The barrier to heat can be said to be minimal. The second-generation single-layer metal reflective window film is produced by evaporation of metals such as aluminum. The insulation effect of this generation of products is directly related to transparency (visible light transmittance). So the color of the window film is no longer important for the metal reflective window film. Many dark window films on the market are inferior. The sellers are blinded by the dark window film insulation effect, so the owner should pay attention to the quality of the window film, not the color.

2. Is the thermal insulation effect better for the dark automotive window film?

Generally speaking, if the quality of window film is divided by color, then transparent window film is better. However, some car owners do not like transparent window films and automotive window film manufacturers also produce colored window films. Generally, there are charcoal black, dark gray, olive green to dark natural color, light natural color and so on. Even the so-called colorless transparent film, in fact, there are differences between the shades, the appropriate choice of colored or darker window film can indeed feel more comfortable under strong sunlight, but we must ensure that the line of sight on rainy days and at night clear, otherwise it may endanger the personal safety of others and is not conducive to driving by yourself. To identify the quality of the window film, visible light transmittance plays an important role.

3. How do I know the VLT of the automotive window film?

People will feel more comfortable under strong sunlight, but the visible light transmittance of the window film should be ensured. Linshang LS110 window tint meter can be used to measure the visible light transmittance of the automotive window film. When purchasing automotive window film, clarity is the most important, otherwise it will affect the driving safety of the driver. The front windshield of the car is the most important window and the VLT requirement of the film is very high. According to Chinese traffic regulations, the visible light transmittance of the front bumper film of the car should be above 70%. For the front film, first of all, it must be clear and safe. Secondly, it is required to have the best insulation effect, which is a good automotive window film. LS110 window tint meter is used to check if the light transmittance of the automotive glass is within the acceptable range.
