What Makes Up a Car’s Windshield?

Posted onSeptember 4th, 2014 byFrank

You probably think your car windshield is just a piece of glass protecting you from the elements when you drive but still allowing you to see. However, they are a bit more complex than that. Keep reading to learn more about windshield anatomy.

Glass: This is the most obvious element of your windshield. Rather than being simply one piece of glass, the windshield is formed by pressing together two identical sheets of glass with no space in between. Since they come from the same mold, they appear as one sheet. Why are two sheets used? This adds extra insulation, makes the glass sturdier and protects it from becoming damaged easily.

Plastic: A layer of laminated plastic holds these two sheets of glass together, adding a safety element so that if the glass does break, any pieces will be held in place rather than flying all over your car. This plastic essentially adds a protective layer making the glass a little stronger and safer.

Glue: An incredibly strong glue called auto-grade neoprene is used to glue the windows into place. It bonds the glass to the metal frame, creating an air and watertight seal. This not only protects the glass, but it also protects your vehicle – and you! If your car were to roll, the bond with the windshield will help prevent the roof from caving in.

Now that you are aware of the parts that make up your windshield, you can have a peace of mind knowing that it is made to protect your vehicle and, more importantly, to protect you and your passengers.
