Laminated glass is one of the safest types of glass available, and is the most commonly used for vehicle windshields. It consists of two pieces of glass with a thin layer of vinyl in between. This combination makes it difficult to break, and when it does, the pieces stick to the vinyl layer instead of flying off. Rear glass, also known as rear window glass, rear windshield, or rear glass, is made of tempered glass, also known as safety glass.
This type of glass is designed to break into small round pieces when impacted, reducing the likelihood of injury. The process of making laminated glass involves bonding several layers of glass together under pressure and heat, with a resin called polyvinyl butyral (PVB). This “tempering process” makes the glass many times stronger than untempered glass of the same thickness. Tempered glass is also a type of safety glass that is manufactured through heat or chemicals to strengthen it. When broken, it breaks into small pieces that do not have extremely sharp edges. Laminated glass was patented for vehicles in 1909 after two women were seriously injured by glass debris following a car accident.
It is preferred for windshields because it can be repaired if necessary, while tempered glass cannot. Tempered glass is used for rear and passenger seat windows because it meets original safety and quality specifications. When replacing a windshield, you have the option of selecting a replacement made by a company that makes OEM windshields, or aftermarket glass made by non-OEM manufacturers. However, more than anything, laminated glass is more popular because if it breaks, the pieces of glass stick to the plastic layer, rather than falling to the ground or, worse, the driver's face or body.
