What Type of Glass is Used in Car Windshields?

Most vehicles have windshields made of laminated glass, which is considered effective in preventing break-ins due to the effort required to break them. Tempered glass is used for the opposite reason, as it is more difficult to break. The glass used for the front and rear door windows and the rear window are made of tempered glass, while the windshield is made of laminated glass. Laminated glass is made up of two pieces of glass with a thin layer of vinyl between them.

The three pieces are laminated together by applying heat and pressure in a special oven called an autoclave. This process makes the glass four to five times stronger than before it was tempered. When a small object hits a piece of safety glass, usually only the outer layer of the windshield that is hit breaks. Safety glass is used in all automotive glass to reduce the likelihood of injury should it break.

Laminated glass is designed to offer the highest levels of safety in the event of an accident. When tempered glass breaks, it is designed to break into small pieces that are less likely to cause additional injury or damage.

The reason for the popularity of glass in automotive parts is the strength, durability, flexibility and versatility they have to offer.

It can serve multiple purposes depending on consumer requirements, and automotive glass is one of them. Different types of glass are used throughout the vehicle because each type has a different purpose. Automotive glass is designed to be resistant to dust, dirt and impacts to prevent annoying particles from sticking to the glass and distorting the driver's line of sight. In your car, the glass used for the windshield is different from the glass used for the side and rear windows. Automotive glass is exceptionally durable and responsible for 60% of the car's structural integrity in rollover accidents, while absorbing 45% of the crash impact during a head-on collision. Laminated glass with its century-old fool-proof design consists of two strong glass sheets that become a single thick sheet by sandwiching a layer of polyvinyl butyral in between.
