The chart above should be used as a guide to material selection, but in no way guarantees steel performance in these conditions.

Notice: Due to the wide variety of projectiles and the fact that ballistic performance is not a quantitative science, Dynamic Armor makes no guarantee or warranties as to the ballistic capabilities of Dynamic Armor plate. Dynamic Armor personnel will provide mill certificates and the independent 3rd party ballistic test results, on a heat lot basis, to demonstrate the typical ballistic performance against various ballistic standards, which can be used as a guide in material selection.

Building Bullet Proof Walls

Bulletproof walls are a vital part of any bulletproof system. Bullet-resistant acrylic windows, stainless-steel cash-trays, and UL-rated frames aren’t worth much if they’re bolted to a wall that can’t stop a shot from a .22 squirrel rifle.

What people commonly call “bulletproof walls” are really “bullet-resistant.” Such walls are made from materials that have been tested and rated by independent agencies who verify that the material can stop a specific number of shots from a specific caliber firearm. For example, a Level 4 bulletproof panel will stop a bullet from a .30-06 hunting rifle, while a Level 7 panel will stop five shots from an AR-15 style tactical rifle.

To these standards, some materials are natively “bulletproof”: a foot-thick concrete wall or two inches of solid steel will withstand many shots from a handgun, sub-machine gun, or rifle. But in most cases building contractors can’t do an entire job in poured concrete and heavy steel slabs; they need to rely on existing or easily constructed stud walls made from light wood or metal frames and sheets of drywall.

Bullet Resistant Fiberglass

For practical purposes, the key to building a bulletproof wall is bullet-resistant fiberglass (also called “opaque armor”). Fiberglass is a two-part laminated material made from a plastic polymer “matrix” reinforced with synthetic fibers. The material is lightweight, strong, and rigid once dried. During production—and prior to setting—fiberglass can be easily molded into any shape. (This makes it a popular material for boat hulls, auto body panels, and so on.)

The fiber at the heart of a bullet-resistant fiberglass panel is a super-tough synthetic mesh. At one time, this was usually DuPont™ Kevlar® fiber (the first such ultra-durable fiber available). Even though that specific brand of bullet-resistant fiber is rarely used in these panels today, it’s still the name most strongly associated with opaque bullet-resistant materials.

The Birth of Kevlar®

Developed in 1965 by DuPont™, Kevlar® was originally used to replace the steel and cloth belts in race car tires. The material itself is a woven synthetic para-aramid fiber (similar to nylon). DuPont had already invented several related aramid synthetic fibers, including Nomex® (which is still used to produce fire-resistant garments for firefighters and test pilots). Kevlar® shares Nomex’s® lack of a melting point and near-complete fire-resistance. But in contrast to Nomex® or nylon, when Kevlar® forms into fibers, its molecules naturally align themselves into long, unbroken chains along the fiber’s entire length. Subsequently, in addition to its fire-resistance, Kevlar® is also highly resistant to abrasion and shows incredible tensile strength—making it perfect for catching bullets.

Kevlar® Panels in Action

Bullet resistant fiberglass panels are made by saturating the synthetic fiber mesh with resin (which forms the “matrix” for the fiberglass). Flat layers of this resin-soaked mesh are then squeezed and baked by an industrial press. The result is a hard, dense, rigid panel. When it strikes one of these panels, a speeding bullet deforms, losing much of its momentum. The layers of resin-caked mesh separate, unfolding like an accordion—and absorbing even more of the bullet’s energy in the process. Then the practically unbreakable strands of Kevlar® enmeshed in the panel act like the walls of a batting cage, preventing the hard projectile (in this case, the bullet) from passing to the “protected” side of the barrier.

A bullet-resistant panel just 1/4-inch thick can stop at least three 9mm bullets fired dead on from just a few feet away. Need to stop a larger bullet? Just laminate together more layers of Kevlar® and resin during the production process, or layer up finished panels during installation.

Building Bullet Proof Walls

Contractors looking to build bulletproof walls start by framing a standard stud wall. They then mount bullet resistant fiberglass panels on the studs, making sure to double-over all seams with additional strips of fiberglass. Finally, the contractor covers the fiberglass wall with drywall or paneling. The resulting bulletproof wall can be finished just like any conventional wall: painted, wallpapered, decorated with framed landscapes or advertising. It’ll stop bullets as well as a bunker, but to any passers-by it’s indistinguishable from a standard wall.

Top Bulletproof Materials for Improved Workplace Safety

It’s an unfortunate truth, but active shooter situations are becoming more common in schools and workplaces. When an active shooter situation arises, you will only want the highest-rated bulletproof materials standing between you and the individual threatening your safety. You have many different types of bulletproof material to consider in your search for the best ballistic defensive structures.

The best type of material to use will depend on your unique application and desired level of protection. Read on to learn about the different bulletproof material options before you forge ahead in the improvement of your workplace safety.

Types of Bulletproof Material

Custom tailored bullet-resistant panels and other protective structures are made from materials designed to stop bullets and shrapnel from penetrating its surface. These materials can effectively absorb the bullets’ energy, preventing the rounds from reaching their target.

Common bulletproof materials include:

Steel

Steel bulletproof materials are heavy duty, yet at just a few millimeters thick, extremely effective in stopping modern firearm rounds. The steel deforms under the stresses from the bullet’s energy but prevents the rounds from reaching their intended targets.

Ceramic

As a material made from clay heated to extremely high temperatures, ceramic sits just below diamonds on the hardness scale, far above the metal used for bullet making. When layered with Kevlar, ceramic can effectively dissipate the energy from rounds of all sizes. When impacted, the ceramic layers disintegrate into a powder under the bullets’ forces.

Fiberglass

When at the appropriate thickness, fiberglass can easily deflect bullets by absorbing the energy through its layers. When placed between steel plates, this ultra-lightweight material effectively distorts the rounds and delaminates to capture the bullets within the structure.

Wood

By increasing the density of wood threefold, seemingly ordinary lumber has the potential to halt a bullet in its tracks. In addition to the strength improvements, the density also increases the durability of the wood to keep it from deforming under the stress of the bullets’ forces.

Kevlar

Perhaps one of the better-known bulletproof materials, Kevlar is a synthetic fiber that’s heat resistant and incredibly strong. It’s also lightweight, making it a popular choice for wearable bulletproof items. Kevlar is used in both military and civilian applications.

Polyethylene

Ultra-high-molecular-weight polyethylene (say that ten times fast) is a plastic that can be found in Tupperware. The ballistic material is remarkably reliable and affordable. Some reports even show that this inexpensive plastic is better than Kevlar at stopping certain bullets because it’s impervious to moisture.

Polycarbonate

The final bulletproof material on our list is Polycarbonate, a strong, transparent material that is used to make glass ballistic resistant.

Material Testing for Ballistic Defensive Structures

Each material undergoes strict ASTM testing to determine its UL Rating, or NIJ level, which directly relates to its ability to stop certain types of ammunition. UL Level one rated ballistic materials may stop 9mm bullets, for example, while UL level eight structures can bring 7.76mm rounds to a halt. You can speak to our defense system experts to determine your ideal level of protection and the materials that will help you achieve your security goals.
