What is the difference between car glass film and building glass film?

I believe many people have heard of car film, but we have heard relatively little about building film. As people’s safety awareness of living standards improves, many people will also choose to paste a layer of building glass film on the glass. Security protection, so many people want to ask what is the difference between car film and building glass film, can they be replaced with each other? Although both can block the heat and ultraviolet rays, and upgrade the protection of the glass, there are still differences between the two. Let's take a look together!

1. Color and light transmittance

First, the intuitive color system is different. The color of the car film is black, natural color, green, etc., especially the front car film, the light transmittance must not be less than 70%. The light transmittance is an important consideration parameter for the car film. The light transmittance of the car film can be used Light rate tester to measure.

In addition, when choosing a car film, try to choose a film with a lighter color and a relatively low reflectivity. Compared with automobile glass film, architectural film has less strict requirements on light transmittance.

Compared with automobile film, building glass film has more rich and diverse colors, high definition, lower reflectivity, and it is optional to cause light pollution. 

At the same time, building glass film, in addition to heat insulation and warmth, also has excellent properties such as blocking ultraviolet rays, filtering glare, strong light reflection (which can protect indoor privacy while enjoying the beautiful scenery outside the window), enhanced glass texture, safety, explosion-proof, bulletproof and other excellent properties.

2. Reflectivity

Both automotive glass film and building glass film have certain requirements for light reflectivity. The reflectance of building glass film is generally higher than that of car film. The internal and external light reflection of car film cannot be higher than 17%, especially for automobiles. Internally, if the interior reflectance of the car is relatively high, the shadows of objects on the dashboard will be reflected on the glass. 

This will seriously interfere with the driver’s line of sight, affect the driver’s correct judgment, and also affect other The driving sight of the driver of the vehicle increases the driving hazard. There is a certain relationship between the light transmittance value and the light reflectivity of the material, so we can indirectly reflect the light reflectivity of the material by measuring the light transmittance value of the material with a light transmittance tester.

Therefore, there is a big difference between automobile glass film and building glass film. If we want to protect building glass film, we can choose high-quality building glass film as much as possible. High-quality building glass film can effectively block solar radiation. 

Entering the room through the glass reduces the heat gain in the building. Therefore, it can not only maintain the indoor constant temperature, improve the environmental quality, and increase the comfort in summer, but also effectively reduce the cost of temperature control.

When we choose car film, we try to choose some high-quality car film with good heat insulation and high light transmittance, and the light transmittance of all car front barrier films should be more than 70%! 

Whether it is building glass film or automotive glass film, we can use a light transmittance tester to measure the real data of the light transmittance of the glass film, and use a gloss tester to measure the reflectivity of automotive glass and the reflectance of building glass film Rate. Use light transmittance tester and gloss tester to choose comfortable and safe building glass film and automobile glass film.

There is still a certain difference between a building film and car film. Building glass film and automobile glass film are different in light reflectance and light transmittance, which should be changed according to actual needs.
