Why should you carry a car window breaker anywhere you go? The answer is too simple right? If we want to be ready during emergency situations then we should have one. Windows are the hardest to break during times when you need to get out of your car especially when it is already sinking or if the door is jammed due to an accident.

Like houses, if the door is locked or if there is no way out, the next thing that comes up in our minds is to go out through the window especially when you are avoiding something or someone like some thief who broke inside or when your house is on fire and the door is not a good way to go through.

Why were car windows made so hard to break anyway? The same as the answer above, it is because in cases of emergency, broken windows might make situation even worse. It is kind of complicated right? You want to break the car window because you should get out immediately but it cannot be that easy because it was designed to protect you. Well, this just depends on the situation.

Laminated car window glasses when broken will stick together because of the PVB material that was used to sandwich it.

How strong is a car window?

Car windows can be any of the two types described below:

  • Laminated Glass

This glass is laminated with polyvinyl butyral (PVB) by using heat and pressure in a way that when it will break, the shattered glasses won’t fly but will fall together as one piece. The PVB is one reason why the glass would not easily break and were designed this way to avoid flying debris to hit body parts of passengers or the driver during a car accident.

Tempered glasses were designed and processed to be ten times stronger than ordinary glasses.

  • Tempered Glass

This is also known as toughened glass because the process is to mainly make the glass ten times stronger than untreated ones. When broken, it likewise is in bits of pieces to prevent severe injuries. Small shatters of glass will only create minor injuries while bigger debris might lead to deeper or major injuries.

For other types of glasses like those bulletproof ones, manufacturers do more complicated processes to combine techniques that will lead to the production of stronger glasses.

How can you break a Car Window Glass?

Like I have mentioned earlier on one of my posts, car window glasses cannot be easily broken even by the strongest elbow or anything that is blunt. Laminated or Tempered glasses can be broken by using sharp pointed objects like knives or simply by a spark plug’s broken porcelain, or by mainly trying your luck with the straight bar of a detachable head rest. You might want to check my previous on how to do those.

The easiest to do is to buy a car survival kit with a window breaker included in it. Car emergency kits may include tools similar to this but if not, you can buy a set of Ecomcrest’s Car Safety Hammer. It is designed to break a window glass and can also be used as a seatbelt cutter with the built in cutter in it. Check the attached video below to have an idea about how to use it.
