The only commercially available Class 1-A fire-rated projectile-resistant building material. Far lighter than steel, ricochet-resistant, and easily installed using ordinary hand-tools, ShotBLOCKER is the ideal reinforcing substrate for bullet-resistant architectural and building projects.

The result of a state-of-the-art design and manufacturing process, ShotBLOCKER is a bullet resistant fiberglass laminate that can be used in structures where increased ballistic protection is desired. From government facilities to check-cashing stations, armored vehicles, and commercial aircraft, ShotBLOCKER provides far greater security and protection in walls, doors, and counters than similar polyester-based ballistic laminates. ShotBLOCKER also meets the requirements for courtroom, gas station, and convenience market armor. ShotBLOCKER complies with applicable federal and state flame and smoke protection regulations.

ShotBLOCKER is readily machined and is far lighter than steel, making it easier to install and repair. ShotBLOCKER can be cut and drilled in the field with commercial quality circular, table, or panel saws. For aesthetic conformity, ShotBLOCKER can be surfaced on site with veneer, drywall, wallpaper, or other wall coverings.
