This is why Windshields Don't Shatter |
Posted: October 8, 2018 |
Like most components of the car, innovation and advancements have rendered windshield much stronger than they were initially. It is essential since faster vehicles tend to collide with more force. First of all, windshields don’t shatter thereby protecting the passengers against shards and windows glass break into small harmless pieces. A brief history of windshields As you might know, cars initially did not have windshield which made it difficult to drive at high speeds; drivers witnessed a need for protection. Wind, bugs, debris and rain made it hard to driver even at low speeds. The first windshield were simple sheets of glass just like the ones used in houses. As car production increased, the prices went down, and people could afford to own a vehicle. But additional traffic meant an increase in the number of accidents. As injuries happened, it was realized that straight glass was a cause of extra harm to the passengers and the driver. Since there were no seat belts either, passengers were launched out of the car through the windshield and fatalities increased, mostly due to lacerations. Why windshields don’t shatter Modern windshields are manufactured with a detailed process. Instead of a single piece of glass, the windshield is now three layers – two layers of curved hardened stuck together with a layer of polyvinyl butyral. This layer binds the sheets together and by the process of heating and cooling rapidly the glass is rendered much stronger. As a result, the glass doesn’t break easily and even it it does the plastic layer holds it together thereby reducing injury. The glass will crack upon impact but stay together. The sharp pieces don’t fly around during the accident. This layer of plastic even provides cushion and prevents the passengers from flying out through the windshield thereby reducing the risk of death. Does every car have laminated glass? This type of glass is known as laminated glass and it is installed in every modern-day car for safety purposes. If you won a Toyota car and need to get a replacement, ensure that you get a laminated windshield for Innova front glass price. The other auto glass including windows, rear windshield and the backlites are made of tempered glass. Tempered glass is another type of safety glass that is rendered tough through various processes. When it is hit, it breaks into minute round pieces that don not cause harm to the passengers. However, laminated glass can be repaired if the damage is minute, tempered glass breaks in totality and warrants replacement. The tempering process makes the glass stronger and therefore, hard to break. Although, it doesn’t have a layer of plastic within. For obvious reasons, you should always go for Original Equipment Manufacturer (OEM) glass for safety.
