Bulletproof glass, ballistic glass, transparent armor, or bullet-resistant glass is a strong and optically transparent material that is particularly resistant to penetration by projectiles. Like any other material, it is not completely impenetrable. It is usually made from a combination of two or more types of glass, one hard and one soft.The softer layer makes the glass more elastic, so that it can flex instead of shatter. The index of refraction for both of the glasses used in the bulletproof layers must be almost the same to keep the glass transparent and allow a clear, undistorted view through the glass.

A) Holds together when shattered. The PVB interlayer keeps the glass bonded,even when broken, resulting in a characteristic spider web cracking pattern across the glass.
B) Cyclone resistant
C) Superior UV blockage
D) Excellent sound damping properties
E) Low visible distortion
Bulletproof glass is used in windows of buildings that require such security, such as jewelry stores and embassies, and of military and private vehicles.
Bullet-resistant glass is constructed using layers of laminated glass.
