Our bullet resistant panels are designed to absorb a bullet’s energy within the panel’s laminate. The composite laminate consists of woven fiberglass reinforced with resin, which makes it capable of defeating a bullet through a process of energy absorption within the laminate. Once the panels have begun to delaminate from impact, any additional shots become progressively easier to defeat because the energy is more readily absorbed by the laminate. In contrast to steel barriers, the fiberglass laminate is designed to prevent ricochet of the bullet as well as spalling to the non-threat side of the panel.
Bullet resistant fiberglass panels are most commonly used in wall assemblies, counters, doors, millwork, cubicles, and desks for many different architectural facility designs. Some of these facilities include Commercial, Schools, Financial, Government, Grid Security, Healthcare, Law Enforcement, Military, Residential, Safe Rooms and beyond.

UL 752 Industry Standards
Underwriters Laboratories, Inc., the world’s oldest and largest, not for profit, independent testing company, wrote the standard for bullet resistant materials. The UL752 standard has been widely accepted throughout the world as the standard for architectural bullet resistive building materials.
Our panels have been tested according to that standard by Underwriters Laboratories, Inc.
A ballistic resistive product becomes “UL Listed” after being subjected to a variety of ballistic tests which include shooting the materials while frozen at -25 degrees Fahrenheit and while heated to 120 degrees Fahrenheit. After the initial testing series, the product is then set up for maintenance testing that involves “pulling random samples” without notice from the manufacturer’s routine production on a quarterly rotation. This rigorous testing schedule ensures that the product is being made without variation and has the highest level of ballistic resistive integrity available.
The following recommendations are designed to assist in the installation of bullet resistant fiberglass panels, as well as to preserve the ballistic protection the panels are designed to provide. Different elements of working with the product and certain challenges are addressed, in addition to important options and expert tips to consider when ordering the product. The material is manufactured by mechanically injecting woven roving ballistic grade fiberglass cloth with a thermoset polyester resin. The impregnated cloth is then placed in a hydraulic hot press and pressed into flat rigid sheets.
Panel Sizes and Cutting
Covenant Security Equipment provides panels in any combination of 3’, 4’ & 5’ widths by 8’, 9’ & 10’ lengths. In the field, panels can be cut with a diamond-grit blade. For electrical boxes and other small openings, a diamond grit blade (available through most builder’s supply in the ceramic tile section) on a reciprocating saw should be sufficient. In addition to wearing protective clothing, a fan can be placed behind the cutting area to help blow away fiberglass particles.
Cut using ordinary carpentry tools. Circular saw, table saw, panel saw, saber saw, etc. Use the following blades: RemGrit "Grit Edge": GC703 7" Circular, GC805 8"Circular, GC915 12" Circular, GJ18 Saber Saw or a Tenryu TSD Series 7". The 7” Blade cuts extremely hard abrasive materials.
Fastening and Drilling
Bullet Resistant Fiberglass may be drilled using high speed steel twist drills. Materials should be drilled at a slow speed. Panels may be attached using self-tapping drywall screws. When attaching a panel to a stud wall on which drywall will be the exterior surface, simply use enough screws to hold the panel to the studs, then come back with a complete screw pattern to the studs when hanging the drywall on top. If a different appliqué is to be used over the panels and a flush surface is required, a counter-sink hole may be used before adding the screws. Panels up to 1-1/8” and thicker may require pre-drilling the fastener holes to prevent the screw heads from breaking, as well as to facilitate the installation. It is recommended that you use a carbide or cobalt tip drill bit at medium speed with medium pressure. Low carbon (high-speed steel) bits may be used, but will typically have a shorter lifespan.
Adhesives and Laminating
Panels can also be attached with the use of adhesives. One product available is PL Premium Polyurethane Construction Adhesive. For stronger adhesion to non-porous substrates, such as aluminum, steel and stainless steel, or bonding one panel to another, a 2-part Methyl Methacrylate (MMA) adhesive may be utilized, such as Plexus MA 320. Laminates can be applied with standard contact adhesives and should be thick enough to avoid transfer of texture to the finished surface. Apply adhesive per manufacturer’s instructions.
Any butt joints or seams create a ballistic weakness at the seam. To insure ballistic integrity, we recommend that you incorporate 4" overlap strips (battens). These strips insure a 2" ballistic overlap on each side of the seam.
For typical wall and mill work installations, a 4” wide batten strip of the same level material should be specified at the butt-joints to provide a minimal 2” overlap from one panel to the next, or each side of the joint. Batten strips are available as separate items or can be cut in the field from raw panels.
The batten strips can be attached directly to the panels and should be used where any vertical or horizontal joints occur. Battens are not required where a 90˚ corner occurs, in which case a panel should simply overlap to the next panel at the corner (see diagram).
By having the panel joints between the studs, the battens can be attached without pushing out the wall further. In the case of electrical cut-outs, an additional 12” high piece of the same level of material may be installed from stud-to-stud, as close as possible to the hole.
Any butt joints or seams create a ballistic weakness. To insure ballistic integrity, we recommend that you incorporate 4" overlap strips (battens). These strips insure a 2" ballistic overlap on the back of each side of the seam. Conformity to curved surfaces can be handled by placing 12" to 18" vertical strips following the inside curvature of the surface to be protected. The same 4" overlap strips should be employed at each joint.
The panels easily accept a wood or plastic veneer using contact cement. It may also be upholstered or painted. To paint we recommend "roughing up" the surface with sandpaper. Panels can be used as a drywall supply alternative, but will need to be installed a little differently, so make sure to check out our installation instructions.

Curved Desk or Wall
Bending panels around a curved desk or wall is possible using Level 1 panels only. A level 3 rating can be achieved by cutting the panels to size and segmenting them or by overlapping the panels to cover the seams. Using stacked Level 1 panels at 1/4” thick will equal the 1/2” Level 3 desired protection.
Level 1 - 6" Radius Maximum
Level 2 - 12" Radius Maximum
Level 6 - 14" Radius Maximum
Level 3 - 20" Radius Maximum
