What Are the Differences between Tempered and Laminate Windshield Glass?


Most people think that glass is glass but in reality, it comes in two common types when you are dealing with safety glass for a variety of uses. This would include the glass in an automobile. The two main types are tempered and laminate and you need to choose the right one to ensure that it is applied properly. That is why it is important to know the difference.

A Look at Tempered Glass

When you are considering the safety glass known as tempered glass, you are looking at a glass that is manufactured using chemicals or heat to provide strength. The reason it is known as ‘tempered’ glass is due to the manufacturing process, which is known as tempering. When tempering is used to manufacture the glass, it is up to four times stronger when compared with other types of glass that are the same thickness.

The strength of tempered glass is only one of the reasons why it is a popular choice. It is also possible to bend tempered glass without breaking it and it has a high level of wind resistance. If the glass is broken, it shatters into round cubes rather than pointy, sharp shards. Most auto glass is tempered glass but it is also used for phone and computer screens as well as in skyscrapers.

A Look at Laminated Glass

The name, laminated glass is rather descriptive. With this type of glass, a minimum of two panes of glass are held together by a layer of polyvinyl butyral (PVB) or plastic. In other words, it is as if it was laminated. Laminated glass may also contain many layers, such as three layers of glass separated by two layers of plastic.

One of the benefits of using laminated glass is that it can protect from UV radiation. It also tends to be more soundproof than other types of glass. Laminated glass can be tinted or clear, depending upon your personal preference and why it is being used. Perhaps the reason why laminated glass is popular more than any other, however, is because the broken glass in laminated glass sticks to the plastic layer rather than falling or flying into the face or body of the driver. It is often used in car windshields but it can also be used in glass floors, skylights, railings, and other locations.

Laminated vs Tempered Glass

Automobiles may use either tempered or laminated glass but they are used for different reasons. Since you cannot repair tempered glass, laminated glass is often used for windshields and tempered is used for the side and rear windows in the vehicle. Both types of glass were developed around 100 years ago. Laminated glass was developed and patented in 1909 after two women were injured in an automobile accident from flying glass debris.

If you have any questions about which is best for you, it’s always best to ask a professional. The technician will determine what glass is best for your model vehicle and use. Regardless of which is chosen, it is important to get the most durable safety glass available for your use.
