What is the Difference Between Tempered and Laminate Windshield Glass
You may have heard of laminated glass and tempered glass, but do you know the difference between the two? Each type of glass undergoes a careful process before being placed on your vehicle. While the two types of glass may appear the same, they have quite a few differences.
Tempered glass is also referred to as toughened glass. It’s made by heating glass to 1200 degrees Fahrenheit in a tempered furnace. Once the glass is hot enough, it’s quickly cooled. This process is called quenching. Once quenching is complete, the glass is four to five times stronger. Tempered glass is difficult to shatter. If it breaks, the glass shatters into small pieces. This makes the tempered glass less likely to cause severe harm. Tempered glass’s durability and safety make it a leading choice for vehicles.
To create laminated windshield glass, three layers of glass are bonded together using high pressure, heat, and polyvinyl butyral (PVB). PVB is a resin that creates high sound insulation, blocks about 99% of ultraviolet light and makes the glass more durable. If damaged, the PVB resin holds the glass together to form a dent instead of shattering and harming vehicle passengers.
What’s the Difference?
Tempered glass and laminated glass are similar in that they both provide a high level of protection to drivers and vehicle passengers. Both types of glass are strong and resilient, making your vehicle safer.
Tempered glass is used throughout your car while the laminate glass is reserved for windshields. Since tempered glass is not as strong, it’s ideal for vehicle windows. This way, if a child or someone is locked in your vehicle, they can break the window and escape.
To protect the front of the vehicle, laminated glass is used. The plastic resin blocks UV light and prevents shattered glass during an auto accident. While tempered glass breaks into small pieces when damaged, the laminate glass will only bend and is less likely to completely break.
