Bullet Resistant Glass

At first glance, bullet-resistant glass looks identical to an ordinary pane of glass, but that's where the similarities end. An ordinary piece of glass shatters when struck by a single bullet. Bullet resistant glass is designed to withstand one or several rounds of bullets depending on the thickness of the glass and the weapon being fired at it. So, what gives bullet-resistant glass the ability to stop bullets?

Different manufacturers make different variations of bullet-resistant glass, but it is basically made by layering a polycarbonate material between pieces of ordinary glass in a process called lamination. This process creates a glass-like material that is thicker than normal glass. Polycarbonate is a tough transparent plastic -- often known by the brand name Lexan, Tuffak or Cyrolon. Bullet-resistant glass is between 7 millimeters and 75 millimeters in thickness. A bullet fired at a sheet of bullet-resistant glass will pierce the outside layer of the glass, but the layered polycarbonate-glass material is able to absorb the bullet's energy and stop it before it exits the final layer.

What is Bulletproof Glass ?

Bulletproof Glass (" Bullet Resistant Glass " or "ballistic glass") is achieved through the multiple layering of laminated glass wherein several lites of glass are bonded together by a 13" polycarbonate material, typically Polyvinyl Butyrol (PVB). It is this PVB interlayer, not the glass lite, which essentially helps sustain a bullet's blow and slows down its penetration. PVB adds another element of safety by maintaining the structural integrity of the glass construction despite its shattering, preventing otherwise large, sharp glass shards from injuring potential bystanders.
