Have you ever wondered why some car windows shatter into tiny pieces while others remain intact even after a severe impact? It’s not magic; it’s the result of the specific properties of auto glass.
There are two different types of auto glass, laminated and tempered. We will go over the differences between these two types of glass, and why the differences are so important.
Laminated Glass
Laminated glass is composed of two sheets of glass with a sheet of PVB (polyvinyl butyral) in between them. They are then fused using high heat to create a thicker and sturdier. Laminated glass is used exclusively in windshields because it will break but it will not fly into shards during a collision. Laminated glass is considered one of the safest kinds of glass because it is designed to withstand heavy impact without shattering.
Tempered Glass
Tempered glass has the opposite purpose compared to laminated glass. While laminated glass is four times as strong as ordinary glass, it is meant to break into lots of small round pieces that won’t cut you like regular broken glass would. Glass can be tempered either by using a heating and cooling process or by using chemicals. Tempered glass is most commonly used for passenger-side windows and rear windows. Sunroofs are typically made using tempered glass, however, some automakers such as Volvo and Tesla use laminated glass instead.
Conclusion
Choosing the right auto glass is crucial for both you and your passenger’s safety. When replacing your vehicle’s auto glass, make sure to choose a reputable auto glass company that will use the right tools and choose the right type of auto glass for your vehicle.
