Bullet-resistant glass

One aspect of security glazing is bullet-resistant glass, which is designed specifically to minimize damage the glazing system might sustain if subjected to gunfire. Bullet-resistant glazing usually includes layers or multiple layers of laminated glass and thermoplastic. The laminated glass used for bullet-resistant glazing is nearly always tempered glass, which, when broken, will shatter into small pieces rather than large shards. The plastic interlayers that laminate the glass hold the fragments together when broken and the thermoplastic between the layers of laminated glass provide elasticity to absorb the bullet’s energy to slow and sometimes stop a bullet, depending on caliber and the distance from which it is fired.
