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 inter-layer called Ethylene Vinyl Acetate(EVA), between it's two or more layers of glass.
The inter-layer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic "spider web" cracking pattern when the impact is not enough to completely pierce the glass. In the case of the EVA, it offers a complete bounding (cross-linking) with the material whether it is glass, poly-carbonate, PET, or fabrics.
Laminated glass is normally used when there is a possibility of impact or where the glass could fall if shattered and also for architectural applications.
