What makes glass bulletproof?

Laminated glass is essentially two pieces of glass sandwiching an inner layer of a polycarbonate material. Laminated glass holds together rather than shattering into shards. Bulletproof glass uses thicker glass than ordinary windshields and a more specialized, high tech inner polycarbonate sheet. When a bullet is fired at the glass, it pierces the first layer of glass but is stopped by the polycarbonate layer. The thicker the bullet proof glass, the better the protection it offers from more powerful bullets.
