The side windows and rear windshield of a car are made of tempered glass. This type of glass is extremely strong and is created 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: laminated glass and tempered glass. Vehicles that circulate today have both laminated and tempered 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. A car is made up of many glass exteriors, including sunroofs, which are available on modern car models. All glass is normally designed to be 100% recyclable, sustainable and non-toxic. In addition to laminated glass, automakers began using tempered glass in the late 1930s.
This type of glass gains strength through a rapid heating and cooling process that strengthens the outer surface of the glass and its core. Tempered glass can also be treated with chemicals and heat treatments; these treatments help give the piece of glass more balanced internal stress capabilities. The reason for the popularity of glass in automotive parts is the strength, durability, flexibility and versatility they have to offer. 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.
If broken, tempered glass is designed to disintegrate into small pieces of glass the size of rock salt.Glass manufacturers continue to explore new ideas to make automotive glass stronger, safer and more adaptable to new vehicles. When it comes to replacement parts, it's important that the same manufacturer as the original glass is used. This ensures that all criteria are met, such as preserving the environment and leaving no carbon footprint behind.
