Types of Glasses in Car Windows
The glasses in car windows fall into two major categories. The auto glass you see is either tempered or laminated. Let us have a quick look at how these are designed and how they are different from each other.
Most of the rear windows and door windows have tempered glass. These windows too can be fitted with laminated glasses. But tempered glass is designed to have a unique feature: shatter-proof.
You must have seen window glasses in your home break. When these glasses break, there are dangerous sharp glass pieces all around. Tempered glass is different. When a piece of tempered glass breaks, it does not shatter into deadly shards. Instead, it breaks into pebble-like pieces, which does not pose danger. That is exactly why you have tempered glass in the rear windows and door windows of cars, SUVs, trucks, vans etc. A special technology is used to design this type of glass, which involves heating and then swift cooling. The use of tempered glass is not limited to the automotive industry alone. There are multiple daily use items and accessories which use tempered glass for the obvious benefits stated above.
Due to its safety properties, laminated glass is used in the windshields of a car, SUV and other vehicles. Unlike tempered glass, the main feature of this type of auto glass is that it is designed to tolerate heavy impact during a crash or collision. Also, this auto glass is shatter-proof.
This type of car window glass has a special design. Two sheets of tempered glass are joined with a layer of PVB (polyvinyl butyral) in between. This is the reason the two portions of glass remain attached even after sustaining a crack or fracture. Even in the event of a collision or crash, the laminated glass of the windshield provides maximum resistance against the impact. The unique design of this auto glass makes it a highly crucial component of the vehicle.
