The automotive sector has introduced numerous technological advancements aimed at enhancing safety, efficiency, and comfort. These innovations include enhancements in auto glass quality and design to improve passenger comfort and safety.

Tempered glass is most commonly used for auto side windows and back glasses, while laminated glass is typically used for windshields.

As a trusted provider of windshield repair and replacement services in Indianapolis and across Indiana, Sentry Glass Inc. is committed to helping you select the ideal auto glass type for your vehicle.

Read on to understand the difference between the two primary types of auto glass windows: tempered and laminated.

What is Tempered Auto Glass?

Tempered auto glass, produced from glass with a higher silica content, possesses greater strength compared to regular glass but can still be fractured relatively easily. Often referred to as toughened glass, tempered glass has a lengthy manufacturing process. First, the glass sheets are heated to extremely high temperatures, followed by rapid cooling.

With its resistance to forceful impacts and enhanced durability, tempered auto glass breaks into smaller, safer fragments known as “pebbles” rather than sharp shards. This is why tempered glass is classified as “safety glass.”

What Is Laminated Auto Glass?

Laminated auto glass, produced by bonding two or more glass sheets with an adhesive resin interlayer, was first developed to protect passengers from harm in an accident. The adhesive layer contributes to its remarkable durability, enabling it to endure impacts without yielding to them.

The interlayer also effectively anchors the glass panels within their frames even when subjected to extreme pressure, safeguarding against break-ins and other potential damages.

Under sufficient force, one side of the laminated glass may shatter while the other remains intact. If the glass breaks in two places, the shards stay connected, forming a spider web pattern.

Furthermore, laminated glass serves to block high-frequency sounds and provides solar protection for vehicle occupants. Another advantage of laminated glass is its ease of repair for rock chips or minor impact-induced damage using transparent adhesive resin.

Tempered or Laminated Auto Glass: Which Is Better?

Tempered and laminated glass are both considered safety glass, but the latter is more expensive. While tempered glass is more commonly used for side windows and back glasses, laminated glass, typically used for windshields, is stronger. However, high costs can deter vehicle owners from choosing laminated glass.

While tempered glass is more durable and less likely to shatter, laminated glass gives protection from the sun’s rays, an added layer of security, and even some soundproofing.
