Bulletproof glass, also known as Explosion Proof Glazing Glass, is a strong and durable material that resists penetration by projectiles. It combines layers of traditional glass with polycarbonate for effective protection. Commonly used in high-security buildings and military vehicles.
Created by the European Committee for Standardization, the European Standard EN 13123/124-1 and EN 13123/124-2 are internationally recognized standards used to qualify the protection provided of security structures and products against blasts.
