What Is Laminated Glass?
Laminated glass is created by bonding two or more sheets of glass with a thin layer of synthetic resin, known as an “interlayer film.” This process involves heat compression to form a unified structure.
The interlayer film, typically made of Polyvinyl butyral (PVB), adheres strongly to both glass and metal. PVB’s high transparency ensures that it does not diminish the glass’s clarity. Moreover, in case of impact causing glass breakage, the interlayer film securely holds the glass shards, preventing them from scattering.
Uses of Laminated Glass
Laminated glass is renowned for its excellent impact resistance. In the event of breakage, it effectively prevents or minimizes the dispersion and fall of fragments. It is particularly suitable for windows in automobiles, railcars, and aircraft, which are subject to strong wind pressure and potential impacts from flying objects. Additionally, laminated glass is widely used in building and residential windows and doors as a security and disaster prevention measure.
Enhancing laminated glass with special sound-insulating interlayer films can provide soundproofing properties. The use of colored or patterned films can also enhance aesthetic appeal. Such creative adaptations expand the versatility of laminated glass in various applications.
