What type of glass is used on car windshields?
Car windshields are made of a specialized type of glass that is designed to provide safety, durability, and clarity for drivers. This glass, known as laminated safety glass, is the standard material used in the construction of modern vehicle windshields.
What is Laminated Safety Glass?
Laminated safety glass is a type of glass that is composed of two or more layers of glass with a plastic interlayer, typically made of polyvinyl butyral (PVB), sandwiched between them. This construction provides several key benefits:
- Improved Safety: If the glass is shattered, the plastic interlayer holds the glass fragments together, reducing the risk of injury to the occupants.
- Increased Durability: Laminated safety glass is more resistant to cracking, chipping, and shattering compared to regular glass, making it less likely to break during an accident or impact.
- Enhanced Clarity: The plastic interlayer helps to maintain the optical clarity of the windshield, even if the glass is damaged.
The use of laminated safety glass in car windshields is a crucial safety feature that has been mandated by governments around the world for decades.
The Manufacturing Process
The process of creating laminated safety glass for car windshields involves several steps:
- Two or more layers of thin, tempered glass are cut to the desired size and shape.
- A thin layer of PVB plastic is placed between the glass layers.
- The glass and plastic layers are then heated and pressed together under high pressure, bonding them into a single, laminated unit.
- The finished laminated glass is then cut, trimmed, and installed into the vehicle's frame.
This manufacturing process ensures that the laminated safety glass meets strict safety standards and provides the necessary protection for drivers and passengers.
Conclusion
The use of laminated safety glass in car windshields is a critical safety feature that has been widely adopted by the automotive industry. This specialized glass, with its multiple layers and plastic interlayer, provides improved safety, durability, and clarity, making it an essential component of modern vehicle design.
Do car windshields use tempered glass?
Tempered glass is most commonly used for passenger side windows and the rear window on automobiles, while laminated glass typically is reserved for your front windshield. When tempered glass breaks, it is designed to shatter into small pieces that are less likely to cause added injury or damage.
Which windshield glass is best?
Laminated Glass
They're considered one of the safest kinds of glass because they are not easy to break or shatter. Most vehicle windshields are made of laminated glass. They're considered to be effective for preventing break-ins because of the effort required to break them.
How do I know if my car has tempered or laminated glass?

Are there different grades of windshield glass?
If you consider the millions of vehicles on the road, the different model years plus the number of different manufacturers it easy to see that there can be variations in quality. Some of the ways Auto Glass can vary include clarity, shatter resistance, and thickness.
What is front car glass called?
The windshield (American English and Canadian English) or windscreen (Commonwealth English) of an aircraft, car, bus, motorbike, truck, train, boat or streetcar is the front window, which provides visibility while protecting occupants from the elements.
What is the best windshield glass?
Laminated glass

What type of glass is primarily used in windshields?
Modern windshields are generally made of laminated safety glass, a type of treated glass, which consists of, typically, two curved sheets of glass with a plastic layer laminated between them for safety, and bonded into the window frame.
What material is used for a car windshield?
laminated safety glass
Modern windshields are commonly composed of laminated safety glass, which consists of two curved sheets of glass with a plastic layer sandwiched between them for safety and glued into the window frame.
Which glass is best for a car windshield?
laminated glass
Most vehicle windshields are made of laminated glass. They're considered to be effective for preventing break-ins because of the effort required to break them. Tempered glass is used for the exact opposite reason that laminated glass is used for windshields.
