Laminated glass is a type of safety glass that holds together when shattered and is used in applications where there is a possibility of human impact or where the glass could fall if shattered.
It reduces the risk of injury by keeping the fragments of glass bonded when broken, and preventing the glass from breaking up into large sharp pieces.
A couple of laminated glazing formations include: using at least two panes of glass and at least one interlayer of plasticized polyvinyl butyral (PVB) resin permanently bonded together under heat and pressure; and the other is formed using two or more panes of glass and polycarbonate, bonded together with aliphatic urethane interlayers under heat and pressure. Upon impact, the bonded interlayers “hold” the glass in place when broken or shattered which provides protection against fall-out and penetration of the opening.
Laminated glass is increasingly used in most new glazing installations and particularly in skylights, exterior storefronts, curtain walls and windows, acoustical insulation, resistance to smash-and-grab burglaries, high security applications, bullet resistant and safety glazing. It is also essential for geographical areas requiring high wind/ hurricane-resistant construction.
