Security glass is a broad category of fortified glass that is used to help resist breakage when encountering projectiles, natural disasters, and even explosions. They consist of laminated glass systems, meaning that two or more sheets of glass are permanently bonded together by an interlayer (see Laminated Glass products page for a more detailed product description). By modifying the heat-treatment of the glass, the number of panes and the interlayer material, various levels of strength and resistance can be achieved. Hartung’s SchoolShield forced-entry resistant glass is designed to protect against hand-held or thrown objects. Bullet-resistant glass will provide protection against projectiles fired by small arms and high-powered rifles. Blast-resistant laminates are designed to resist against the direct blasts from shock waves and help maintain the structural integrity. Finally, hurricane-resistant glazing is tested to provide protection in extreme windstorms. Whatever your needs may be with Security Glass, Hartung has the capabilities to work with you to develop the product that will meet the requirements of your projects.
