Laminated glass is one of the most popular types of glass used in vehicles. It is composed of two separate sheets of glass that are glued together with PVB (polyvinyl butyral) and then melted at high temperatures. This type of glass is used for both the front and rear windshields, as well as the side and rear windows. In addition, there is also tempered glass, which is used for the rear windshield and the front and rear door windows.
Laminated glass has been around since the 1920s, when two sheets of glass were placed together with a PVB (polyvinyl butyral) sheet between them. This process changes the glass so that, if broken, it breaks into small pieces with blunt edges instead of sharp shards. This makes it safer for passengers in the event of an accident. In addition, laminated glass can be repaired, while tempered glass must be replaced completely.
Tempered glass is created by rapidly heating glass to more than 1000 degrees Fahrenheit and then rapidly cooling it to room temperature. This process gives it more strength than laminated glass and makes it less likely to break from stones or debris. However, it does not provide any cushioning like laminated glass does, so it is only used for windows and not for windscreens. Automotive glass plays an important role in providing safety and protection for passengers in the event of an accident.
It is responsible for 60% of the car's structural integrity in rollover accidents and absorbs 45% of the crash impact during a head-on collision. Now that you know all about the importance of high-quality automotive glass, let's take a look at the two leading automotive glasses that dominate the market: laminated and tempered. Laminated glass provides a cushioning effect that prevents passengers from being fired from the car in a head-on collision, while tempered glass disintegrates into small pieces and blunt edged cubes to protect passengers from damage. In conclusion, vehicles today use both laminated and tempered glass for different purposes. Laminated glass is used for windshields due to its non-shattering properties, while tempered glass is used for windows and rear windshields due to its strength and cost-effectiveness.
