Car Safety Glass is Stronger Than You Might Think

You have windows all throughout your home or apartment, and if you’ve ever broken one (guilty here on a few occasions), you know that when they shatter, glass goes everywhere. Hopefully you’ve never been involved in an auto accident, but if you have, you probably noticed that car windows don’t shatter so easily. Why?

Safety glass!

So, what makes safety glass different? Safety glass is made up of several layers of glass – usually two or more – and a thin layer of clear, plastic film which is sandwiched between them. This film helps keep glass from flying everywhere when broken, which could cause injury to you, or any other occupants in your car.

Safety glass was first used in cars in the late 1920s, and before that, the car windows were made similar to those windows found in your home. Ouch! According to glasslinks.com, the safety glass in cars today can withstand three times the impact velocity of standard windshields.

Most side and rear windows in cars are made from a tempered safety glass. This tempering process can strengthen glass up to 10 times that of un-tempered glass. It involves heating the glass and contouring it as it heats. While very strong, tempered glass can break, but when it does, it shatters into rounded, smaller pieces that are less likely to injure someone.
