Should Explosion-Proof Film Be Applied on the Inside or Outside of the Glass?
2 Answers
Explosion-proof film should be applied on the inside of the car glass. To prevent damage from external environmental factors, if applied on the outside, the film and windshield wipers may cause scratches. Rain or windblown sand will continuously erode the film, affecting its performance. Here is some relevant information about explosion-proof film: 1. The base layer of explosion-proof film is polyester, which has anti-tear and anti-puncture properties. 2. Through the adhesive layer of the film, the strength of the glass behind the film can prevent accidental injuries caused by broken glass. 3. The most important function is explosion-proof. When external force impacts and breaks the glass, the film will adhere to the glass fragments, preventing further injuries and improving the safety factor. 4. After applying explosion-proof film, it can effectively slow down the rise and fall of interior temperature to a certain extent and save about 30% of power consumption. 5. The color of the explosion-proof film can be chosen according to the owner's preference. Light-colored films such as green, sky blue, and gray are preferred for the front windshield, as these colors are more comfortable to look at and do not affect heat insulation performance.
The explosion-proof film is applied to the inner side of the glass, just like the ones on my car. If it's not applied on the inside, it can easily get scratched or worn from the outside, which would defeat its explosion-proof purpose. For example, when I last had the film installed, the technician reminded me that the temperature inside the car changes less, which helps protect the film from expanding or deforming, and it doesn't obstruct the view. If applied on the outside, water marks from rain or car washes could seep in, causing bubbles or peeling, and the reflection could also affect driving safety. I tried installing it myself once, and the film cracked within a few days. Looking back now, saving that little bit of money wasn't worth it—it's better to have professionals install it. Not only does it block UV rays and reduce interior aging, but it also provides privacy protection. The key point is that if it's not applied in the right place, in case of an accident where the glass shatters, the fragments could still injure people, making it lose its safety purpose. So next time I apply the film, I'll make sure it's installed on the inner side.
