The side windows and rear windshield of a car are made of tempered glass. Tempered glass is extremely strong, like laminated safety glass, but it differs in a few key ways. Tempered glass is manufactured by rapidly heating glass to more than 1000 degrees Fahrenheit and then rapidly cooling it to room temperature. There are two main types of glass used when building cars.
Vehicles that circulate today have laminated glass or tempered glass. Automatic glass is tempered or laminated. The glass generally used for the front and rear door windows and the rear window are made of tempered glass, the windshield is made of laminated glass. The glass generally used for the rear window and the front and rear door windows are made of tempered glass, while the windshield is made of laminated glass.
Tempered glass is just as important to a vehicle's safety as laminated glass, but it differs greatly in both form and function. This type of glass is used for the surrounding windows of vehicles (also called side windows) and the rear window (or backlight). Tempered glass is created by rapidly heating and then cooling the glass to room temperature by introducing it through a blower system. Safety glass is used in all automotive glass.
It is made to reduce the likelihood of injury, should it break. Windshields are manufactured from a lamination process. Your car's windshield glass is made of laminated glass, which is designed to offer the highest levels of safety in the event of an accident. 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. When a small object hits a piece of safety glass, usually only the outer layer of the windshield that is hit breaks. Glass manufacturers continue to explore new ideas to make glass stronger, safer and more adaptable to new vehicles. However, in severe impact situations, the glass “breaks”, but usually does not separate because broken glass pieces generally adhere to the vinyl inner liner.
This type of glass is used in the side and rear windows of the vehicle and gains strength through a rapid heating and cooling process that strengthens the outer surface of the glass and its core. In addition, 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. That inserted layer of PVB is what allows the glass to absorb energy during an impact and gives it resistance to the penetration of flying projectiles. The second type of aftermarket automotive glass comes from the OEM, but was created on a different production line.
Glass, in this case, is used to refer to the side windows, the deflector glass, the ventilation glass and the glazed roof (if the car has one). However, the most important glass in any vehicle is the windshield, and it is made of laminated glass. Although laminated glass is widely used in the automotive industry, it has a wide range of applications and can work well in any situation where there is a potential for impact by a person. When it comes to glass, this means that the replacement glass used was manufactured by the same manufacturer as the original glass.
Different types of glass are used throughout the vehicle because each type of glass has a different purpose. 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. The modern vehicle incorporates more glass than ever before, including larger windshields, sunroofs and even glass panels that replace the roof completely. Glass and PVB sheets were heat fused and laminated safety glass was born.
Laminated glass is made by sandwiching a layer of polyvinyl butyral (PVB) between two pieces of glass. Laminated glass, with a 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 the middle. . .
