Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA), between its two or more layers of glass. It can be broken, but the fragments tend to adhere to the plastic layer and remain largely intact, reducing the risk of injury.
Laminated glass is often used in exterior storefronts, curtain walls, windows and is also used to increase the sound insulation rating of a window.
