Laminated glass is a type of safety glass that holds together when shattered. It consists of two or more layers of glass with one or more interlayers of plastic (usually polyvinyl butyral or PVB) sandwiched between them. These interlayers are bonded together under heat and pressure, forming a single, durable, multi-layered glass unit.
When laminated glass is broken, the fragments tend to adhere to the interlayer rather than scattering and potentially causing injury. This makes it an ideal choice for applications where safety, security, and durability are critical.
Key Characteristics and Benefits
Safety: In the event of an impact, laminated glass reduces the risk of injuries, as the broken glass shards are held together by the interlayer.
Security: Laminated glass offers increased resistance to break-ins and vandalism, as the interlayer makes it more difficult to penetrate.
Sound Insulation: The interlayer in laminated glass acts as a barrier that dampens sound waves, providing improved acoustic insulation compared to regular glass.
Fade Protection: The interlayer filters out harmful UV rays, helping protect interior furnishings from fading.
Decorative Glass: Laminated glass can be customized with various colors, patterns, and finishes to achieve unique aesthetic effects.
Laminated Glass Applications
Laminated glass is widely used in both residential and commercial applications where safety, security, and durability are critical. Some common applications include:
Windows and Doors: Laminated glass is used in windows and doors for added security, sound insulation, and UV protection.
Skylights and Canopies: Laminated glass is preferred for overhead glazing applications due to its safety features.
Balustrades and Railings: Laminated glass is used in balustrades and railings to provide a safe and durable barrier.
Hurricane-Resistant Glazing: Cardinal’s Sea-Storm glass is used in hurricane-resistant windows and doors to withstand wind-borne debris and extreme wind pressures.
Bullet-Resistant and Blast-Resistant Glazing: Special laminated glass configurations are used in bullet-resistant and blast-resistant glazing for enhanced security. Please contact Cardinal LG for details on this type of application.
Laminated glass is a versatile and reliable glazing material that offers a wide range of benefits for various applications. Its safety, security, and durability make it a preferred choice for many architectural applications.
