Which type of glass is most frequently used in side windows?

Tempered glass is the most frequently used type of glass in side windows of vehicles due to its strength and safety properties. It is created through a process of extreme heating and rapid cooling, which makes it significantly more shatter-resistant than regular glass. When broken, tempered glass fragments into small, blunt pieces, decreasing the likelihood of injury during a collision or an accident.

This type of glass not only withstands greater impact but also can handle temperature fluctuations better than other glass types. Laminated glass, while strong and safe, is primarily used in windshields where occupant protection and durability against debris impact are critical. Safety glass is a broad term that includes both tempered and laminated glass, but it does not specifically refer to side windows. Hardened glass is not a common classification used in vehicle construction. Therefore, tempered glass is the go-to choice for side windows due to its specific properties that cater to the demands of automotive applications.
