Bullet Resistant Glass
Introduction
Bullet Resistance glass consists of a combination of three or more pieces of glass permanently bonded together by two or more interlayers of tough and durable polyvinyl butyral (PVB). This interlayer exhibits the characteristics of a superior security glass with its high impact resistance against weapons and ammunition. The composition and thickness of the laminated glass determine the degree of resistance against concerted attacks from a variety of weapons. When broken by impact, the glass will adhere to the interlayer and generally stay in the frame, minimising the risk of injury from sharp edges, flying or falling glass and strongly resists penetration by the impacting object. Maximum security is achieved when the projectile does not penetrate the glass and no splinters of glass are flung off from the rear face of the glass unit.
