Laminated Auto Glass
Laminated Auto Glass
Laminated auto glass is a type of safety glass produced by interlaying 2 sheets of glass with a thin layer of PVB film (Polyvinyl Butyral) which could be clear, colored or clear with a shaded band. This technique is what keeps the glass bonded in case of breakage & does not fall into pieces; a “spider web” is created instead. That is why it is used in the manufacturing of the car’s front windshield. The PVB & the glass are sealed through a series of pressure & then heat. Not only does the PVB absorb energy during an impact but it also prevents up to 95% of the harmful ultraviolet rays from the sun.
Tempered Auto Glass
Tempered Auto Glass
Tempered auto glass is a single layered type of safety glass used in the car is surrounding windows (sidelights) & the back windows (backlights) in addition to the ventilators & sunroofs. This type of glass is available in all colors & with additional necessary accessories especially in the backlights such as the heaters & alarm sensors. It is produced by heating the glass up to melting point (approx. 650 degrees) then rapidly cooling by air. This is what makes the tempered glass 5 times stronger than its natural state. In case of breakage, it breaks into non-edged small pieces that are not hurtful.
Difference between Laminated Auto Glass and Tempered Auto Glass
Laminated glass and tempered glass are both types of safety glass used in various applications. Here are the main differences between the two:
1. Manufacturing Process:
- Laminated Glass: Laminated glass is created by sandwiching a layer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) between two or more layers of glass. The layers are bonded together under heat and pressure, creating a single, durable unit.
- Tempered Glass: Tempered glass is produced by heating the glass to a high temperature and then rapidly cooling it through a process called quenching. This creates internal tension that makes the glass much stronger than regular annealed glass.
2. Strength and Safety:
- Laminated Glass: Laminated glass is designed to remain intact when shattered. When broken, the glass adheres to the interlayer, preventing it from falling apart. It offers excellent resistance against impact, making it a good choice for areas where safety is a concern, such as automotive windshields and building facades.
- Tempered Glass: Tempered glass is several times stronger than annealed glass of the same thickness. When it breaks, it shatters into small, relatively harmless pieces with rounded edges, reducing the risk of serious injury. Due to its safety properties, tempered glass is commonly used in shower doors, windows, and glass table tops.
3. Breakage Behavior:
- Laminated Glass: When broken, laminated glass may crack or spider web, but the broken pieces tend to stay in place due to the interlayer, offering continued protection against external elements.
- Tempered Glass: Tempered glass breaks into small, granular pieces instead of sharp shards. This feature minimizes the risk of injury, making it suitable for areas where safety is a concern.
4. Applications:
- Laminated Glass: Due to its ability to maintain its structure when broken, laminated glass is often used in areas where safety and security are paramount, such as in car windshields, building facades, and areas prone to natural disasters or forced entry attempts.
- Tempered Glass: Tempered glass finds application in situations where safety is essential but complete structural integrity isn't required. It is commonly used in residential and commercial windows, shower doors, glass railings, and oven doors.
In summary, laminated glass offers improved safety by holding together when shattered, while tempered glass provides strength and reduced risk of injury through its shattering pattern. The choice between the two depends on the specific requirements of the application and the level of safety needed.
