What Type of Glass is Used in Cars?

Tempered glass and laminated glass are the two main types of glass used when building cars.

Automatic glass

is either tempered or laminated. The glass used for the rear window and the front and rear door windows is usually tempered, while the windshield is made of laminated glass. Laminated glass is added to cars as a standard safety measure to prevent accidents.

It holds two pieces of glass together, with a thin layer of plastic between them. When the laminated glass breaks, the main piece remains intact and the broken piece falls off, preventing people inside or outside the vehicle from being injured by flying shards of glass. Laminated glass is also used in car sunroofs for added safety, clarity, and tint options. The key advantage of laminated glass in cars is that it can withstand serious accidents and can be used for both front and rear windows, offering superior protection for drivers and passengers.

For small cracks in laminated glass, there is a repair option, which is not the case with tempered glass. A specialized resin is used to fill the crack, restoring glass strength and visual properties. The main disadvantage of laminated glass is that it is prone to impact breakage even with little force and therefore the cost of replacing a new windshield is very high in car maintenance. Tempered glass has more strength than laminated glass and is therefore less susceptible to breakage by stones or debris. It is also cheaper and easier to maintain, which is why many commercial operators still use tempered glass windshields on their buses, trucks and trucks.

The main drawback is the absence of a PVB layer, which can prevent a harmful element from entering the car's chamber. When tempered glass breaks on impact, it cannot protect occupants. 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. It is manufactured by rapidly heating glass to more than 1000 degrees Fahrenheit and then rapidly cooling it to room temperature. Laminated safety glass was born when two pieces of glass and PVB sheets were heat fused together.

This tempering process induces compressive stress on the surface of the glass and gives it strength and durability far beyond normal glass. At the time of purchase, you can directly ask the manufacturer or supplier about the type of automotive glass you have. Automotive glass can also be used for sunroofs; they are designed to be UV-resistant to help passengers enjoy natural light without harmful UV rays.
