What type of glass is typically used for automotive windshields?

The correct answer is laminated glass, which is commonly used for automotive windshields. Laminated glass consists of two layers of glass with a layer of polyvinyl butyral (PVB) sandwiched between them. This construction provides several key benefits that make it ideal for automotive applications.

Firstly, laminated glass enhances safety by holding shattered glass together during an impact. This minimizes the risk of injury from flying glass shards, offering greater protection to vehicle occupants. It also helps maintain a clear view during accidents, as the glass is less likely to break apart.

Additionally, laminated glass has excellent sound-dampening properties, contributing to a quieter cabin experience by reducing noise intrusion from outside. This is particularly important in automotive design, where comfort and driving experience are key considerations.

Laminated glass also provides better ultraviolet (UV) protection, shielding passengers from harmful UV rays while reducing the heat that enters the vehicle's interior, thus improving comfort and reducing the load on the vehicle's air conditioning system.

In contrast, annealed glass is a basic type of glass that does not offer the same level of safety and durability. Tempered glass is stronger than annealed glass but is often used for side and rear windows rather than windshields, as it
