Hardened & Bulletproof Glass

Hardened & Bulletproof Glass Overview

Bullet-Resistant Glass

A critical part of protection practices, bulletproof glass, also known as bullet-resistant glass, is installed all over the world for both military and commercial use, including windows on armored vehicles, public buildings and even jewellers. Contrary to popular belief, bulletproof glass isn’t completely impenetrable.

Hardened Glass Production

Made in thickness between 3⁄4 to 3 1⁄2 inches (19 to 89 mm), bulletproof glass is traditionally constructed from a combination of two or more layers of laminated glass and/or polycarbonate, the more layers, the greater the protection. Polycarbonate is softer than glass and so it’s the introduction of this layer that increases elasticity and prevents shattering.

  • Thinner glass is said to be able to resist up to three 9mm rounds
  • Thicker glass can withstand up to five 7.62mm NATO rifle rounds

ALON

ALON is made from Aluminium oxynitride and is the latest advancement in bulletproof glass technology. A transparent ceramic composed of aluminium, oxygen and nitrogen, ALON is said to be capable of resisting a single.50 BMG (Browning Machine Gun) round.
