What Type of Glass is Used in Windshields?

Do you know the difference between windshield glass and window glass? As you take care of your vehicle and keep up with its maintenance, you may want to familiarize yourself with the different types of glass found in your car or truck, which serve different purposes and behave uniquely in a collision or when struck by an object. In today’s blog, A1 Windshield teaches you about the glass used in the windshield and windows of your vehicle. 

What Type of Glass is Used in a Windshield?  

Most windshields are made with laminated glass. Laminated glass is formed by pasting PVB (polyvinyl butyral) resin glue film between two or more regular glass sheets. Next, it’s taken through heating, pressing, and bonding the product together, which helps create the curved or flat glass product, depending on the final desired outcome for the manufacturer. 

There are many reasons why companies use laminated glass to assemble windshields. First, laminated glass is the safest option for windshields because of how it reacts on impact with objects. Laminated glass does not break when involved in a collision and is designed never to shatter when it’s met with a heavy blow. Drivers can rest assured that if they are involved in an accident, the laminated glass in their windshield will not cause further harm by breaking off into dangerous shards.

What Type of Glass is Used in Car Windows? 

Car windows along the front and rear sides of the vehicle are typically made with tempered glass. Tempered glass is nearly four times stronger than what we could consider normal glass, which is classified as “annealed glass”. In most cases, the tempered glass breaks into small pieces, roughly the size of a pebble, making it safe for passengers in a car accident. When tempered glass is struck by an object (such as a rock), it cannot be repaired.
