Bullet-resistant fiberglass sheets


Bullet-resistant fiberglass sheets are manufactured to defeat most levels of weaponry as described by UL and NIJ performance standards, including handgun and rifle threat levels.

These sheets, marketed under the LUMAgard trade name, are often used in courthouse and law-enforcement facilities, banks and other money-handling operations, guard booths, armored vehicles, equipment enclosures and many other kinds of installations where protection is needed.

Panels from production are routinely tested to confirm superior performance. Testing is conducted often by nationally-recognized testing laboratories, including Underwriters Laboratories, Inc.

UL-listed bullet-resistant sheets are manufactured to ballistic levels defined by Underwriters Laboratories Standard UL 752. Sheets designed to defeat specific threats defined by National Institute of Justice Standard NIJ 0108.01 are also manufactured.

Refer to the Fiberglass Armor Reference Table for more information.

LUMAgard Fiberglass Armor is UL Listed for Levels 2,3,4 and 6

*Note that AG-1 bullet-resistant fiberglass sheets meet level 1 of NIJ Standard 0108.01. (There is no corresponding UL level.) The AG-1 material (3/16 nominal thickness) can be curved to a gentle simple radius. Three sheets of the AG-1 material layered together meet requirements of Level 3 of UL 752.



LUMAgard Installing Bullet-Resistant Fiberglass Sheets

LUMAgard bullet-resistant fiberglass sheets are manufactured in three standard sizes: 3' x 8', 4' x 8' and 4' x 10'. Larger sheets may be available in some products, depending on the nature of the requirement.

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.
