What Causes Sudden Glass Breakage?
2 Answers
Sudden breakage of car glass can be caused by external force damage, defects in glass manufacturing leading to cracking, or installation factors. Below are the specific reasons: External force damage: Such as bumps during handling or intentional strikes. Defects in glass manufacturing leading to cracking: For example, factors like bubbles, cracks, or impurities present during glass production. Installation factors: If the installation gap is too small or the glass directly contacts the frame, it can create pressure on the edges or corners of the glass, inducing breakage. Car glass cracks are generally repaired using specialized repair tools and repair fluid. The repair fluid is applied into the crack using the tool, solidifying to eliminate the gap and achieve repair. It's important to note that if a crack appears, it should be repaired as soon as possible. If the damage is severe, immediate replacement is necessary. This is because during driving, the windshield must withstand wind resistance and constant vibrations. Over time, small cracks can gradually extend, lengthening and expanding in area.
Once while I was driving on the highway, I suddenly heard a loud bang, and a crack appeared on the windshield. Later, the mechanic told me it was mainly caused by hard objects like stones being flung and hitting the glass. When driving at high speeds, stones kicked up by the wheels or small debris on the road can strike the windshield, which is especially common on highways. Additionally, extreme weather conditions like hailstorms can instantly crack the glass, particularly in cold regions where the glass itself becomes more brittle. If there were minor damages to the glass that weren’t repaired in time, vibrations could also cause them to expand into full cracks. I’ve also heard that improper modifications or excessive adhesive attachments can worsen the impact. If this happens, the first thing to do is slow down, pull over safely, and inspect the damage. Never continue driving with a cracked windshield, as it could shatter at any moment, which is quite dangerous. It’s advisable to regularly check the condition of your windshield and try to park away from areas with many trees to minimize risks.
