Hello, the car mentioned in your question should be Beijing Hyundai Elantra. It is normal for film to break glass, but it may break, which is what we often say. The following is an analysis of broken glass. 1 technical reasons, because the installation of solar film needs to heat the car glass, uneven heating and high temperature may lead to glass breakage. 2 film, special solar film for automobile, has certain flexibility. After installation, the film shrinks, resulting in excessive glass pressure. Due to climatic reasons, the car has just been installed with a solar film, and the glass will break in an alternating hot and cold environment. Car glass can be broken before installation. Although it has passed the security check, a small crack and gap can cause the glass to be damaged after pasting. I suggest you pay for the glass from the insurance company first, and then ask for free at the film pasting place. Because your glass wasn't broken on the spot, the reason for it can't be clear, and the merchant can't compensate >
