Automotive Glass

Providing a distortion-free view of the world outside. A fundamental requirement for automotive glass

The most basic requirement of automotive glass is to provide a view of the world outside without distortion. But even something that obvious is difficult for automotive glass and requires a very high level of technology. Corresponding to the evolution of vehicle design, automotive glass is becoming larger and larger, while curved, streamlined glass has become the standard. However, simply curving glass makes it function like a lens, giving scenery outside a distorted look. No matter how complicated its shape, glass must offer an as-is view of the world when looking through it. That is a basic requirement for automotive glass and also the most important.

2 basic types of automotive safety glass

Laminated glass is used for windshields, while tempered glass is used for side windows

Laminated glass is used for windshields, while tempered glass is used for side windows

There are two basic categories of automotive glass, laminated and tempered, that play an important role in protecting passengers. Laminated glass is a safety glass that is primarily used for windshields. A film is inserted between two sheets of fabricated glass, making it difficult to shatter and reducing the risk of debris from penetrating the windshield while driving. Tempered glass, on the other hand, is a glass that has been heated and rapidly cooled to increase its strength, so it breaks into small shaped pieces in the unlikely event of breaking. It is used primarily for side window and rear glass.

Providing high value-adding functions

Vehicles are evolving day by day. In the midst of this, the needs of automotive glass are diversifying and becoming more sophisticated - for example, improved driving safety in rainy weather, and more comfort for passengers in the summer. Also, there is currently demand for additional features with enhanced designs such as communication functions that enable high-level information exchange while providing safety.
Other examples include: water repellent glass that features a fluorinated coating on door glass to provide both water repellent properties and durability to increase visibility in rainy conditions, and IR & UV cut glass that not only increases comfort for passengers by significantly cutting the burning sensation caused by IR and UV rays, but also helps improve fuel efficiency by moderating the use of air conditioning.
Additionally, glass antennas and head-up displays that safely provide drivers with necessary information are expected to be influential in our advanced information society. AGC group responds to these complex, high-level needs by utilizing our integrated group structure in diverse areas including glass, chemistry and electronics, and our global power in technological development.
