Install the largest continuous panel that is practical. Joints are ballistically weak. Reinforce butt-joints with 4" strips of the same product either in front of or behind the joint.

Fiberglass armor sheets are ordinarily installed by mechanically fastening the sheets to the side of the supporting structure that the projectile would come from. Fiberglass armor sheets expand slightly upon impact as part of the normal dissipation of energy from incoming projectiles. If sheets are to be installed against a very hard surface (like masonry block or cement board) leave a 1/4 -inch (minimum) gap by shimming the fiberglass sheets.

Finishing materials, sheet rock, wallpaper and decorative laminates bond readily to the surface with standard construction adhesives.

LUMAgard™ fiberglass armor sheets are readily cut and drilled using tools commonly used to cut and drill metals. Dust generated during cutting and fabricating can be hazardous. Wear eye protection during fabrication. Wear a protective mask if necessary to avoid inhaling dust. The dust may be irritating to the skin. Refer to materials safety data sheet (rev. 9/3/02) for additional necessary safety information.
