MC504BR - ShotBlocker® is the only commercially available Class 1-A fire-rated projectile resistant building material. Lighter than steel, ricochet-resistant, and readily installed with ordinary power hand tools, ShotBlocker is the ideal reinforcing substrate for ballistic resistant architectural and building projects. ShotBlocker consists of woven glass fabric impregnated with a high temperature phenolic resin system. Unlike some competitive ballistic products, it does not require a messy and labor intensive wet lay-up process. From government facilities to bank teller stations, armored vehicles, and commercial aircraft, ShotBlocker provides far greater security and protection in walls, doors, and counters than similar polyester-based anti-ballistic laminates. ShotBlocker also complies with several federal and state flame and smoke protection regulations.
