Laminated glass is a type of safety glass that remains intact when broken. It is made by bonding two or more layers of glass with one or more layers of a plastic interlayer, typically polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking into large sharp pieces. This process of layering and bonding under heat and pressure results in a durable and versatile product.
Key Features:
1. **Safety and Security**: Laminated glass offers increased safety as it tends to stay in place if shattered, reducing the risk of injury from flying glass shards.
2. **Sound Reduction**: The PVB interlayer acts as a sound barrier, reducing noise transmission through the glass.
3. **UV Protection**: Laminated glass can block up to 99% of ultraviolet rays, protecting interior furnishings from fading.
4. **Vandal Resistance**: The tough interlayer makes it more difficult for intruders to penetrate the glass.
5. **Aesthetic Appeal**: Laminated glass can be customized with various colors, tints, and coatings to enhance the visual appearance and energy efficiency.
Applications: – **Residential Windows**: For improved safety and security.
- **Automotive Windshields**: To prevent shattering and protect occupants.
- **Commercial Buildings**: In storefronts, curtain walls, and skylights.
- **Balustrades and Railings**: For transparent barriers that offer safety without obstructing views.
- **Furniture**: Used in table tops and shelves where durability and safety are important.
Variants: – **Standard Laminated Glass**: Basic configuration with standard thicknesses.
- **Acoustic Laminated Glass**: Specialized for noise reduction, often used near busy roads or noisy areas.
- **Bullet Resistant Laminated Glass**: Engineered to withstand impact from bullets, commonly used in banks and government buildings.
- **Thermally Insulated Laminated Glass**: Incorporating low-emissivity (low-E) coatings or other insulating features to improve thermal performance.
Laminated glass is a preferred choice in applications where safety, security, and sound insulation are critical.
