What Causes Sudden Breakage of Car Glass?
2 Answers
Sudden breakage of car glass can be caused by external force damage, defects in glass manufacturing, or installation issues. Below are the detailed explanations: External force damage: For example, impacts during transportation or intentional strikes. Defects in glass manufacturing leading to breakage: Such as bubbles, cracks, or impurities present during glass production. Installation issues: 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, leading to 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 the repair. It is important to note that if cracks appear in the glass, they should be repaired as soon as possible. If the damage is severe, the glass should be replaced promptly. This is because, during driving, the windshield must withstand wind resistance and constant vibrations. Over time, small cracks can gradually extend, lengthen, and expand in area.
After driving for so many years, I've encountered windshield cracks several times. The most common cause is small stones flying off the road hitting the glass, especially at high speeds where even a tiny pebble can cause major cracks in the windshield. Temperature fluctuations are another major issue - like blasting hot air immediately after washing the car in winter, or turning on cold AC right after summer sun exposure. The thermal expansion and contraction creates stress cracks. Older car glass becomes more prone to shattering as wear reduces its strength. Improper installation or slamming doors too hard causing uneven pressure can also lead to sudden breakage. I remember once my friend's car had its glass suddenly shatter in a parking lot - inspection revealed it was due to untreated micro-damage from a previous accident repair. Safety first - if this happens, immediately pull over, secure fragments with tape, and get professional replacement to avoid road hazards.
