Bullet Resistant Glazing
Security Glazing, Safety Glass, Polycarbonate
Standard Bent Glass Corp provides bullet resistant glass products for protection against a wide range of ballistic threat levels. All Glass products combine multiple layers of glass and polyvinyl butyral (pvb) with "no spall" protection and UL Listings for various levels of resistant protection. Glass-Clad Polycarbonate products combine the durability and abrasion resistance of glass on the "attack" side and the impact resistance of polycarbonate to the "witness" side, providing thinner and lighter security glass products with "no spall" protection. Laminated Polycarbonate products combine polycarbonate with polyurethane interlayers to achieve various levels of ballistic threat and extensive attack resistance. Exposed polycarbonate surfaces are abrasion resistant for maintenance. Advanced Transparent Armor (ATA) products contain glass, polycarbonate and a proprietary polymer, which offer a lightweight solution while providing high levels of ballistic resistance. Our Single Responsibility® program covers all of our glass products. The charts below provide a quick reference for bullet resistant glass product choices.
