Bulletproof glass is an incredible investment in peace of mind. Also known as ballistic glass, bulletproof glass is made of transparent materials that are resistant to penetration by bullets and other projectile objects. While not 100% impenetrable, it has a level of flexibility that allows it to sustain impact by bending instead of shattering. Whether newly installing or upgrading windows for a commercial building or a private home, this safety feature is something to consider. Property owners considering the options should know that bullet-resistant glass cost is actually influenced by a range of different factors.
FACTORS AFFECTING THE COST
There’s no such thing as a one-size-fits-all price quote for bulletproof glass. Pricing is based on the specific selections you make for the space you’re creating. Unlike companies that install traditional glass windows, contractors offering bulletproof glass spend time working on customization with their clients to ensure that specifications meet the needs of the space being designed.
Bulletproof Glass Rating
Not all bulletproof glass performs the same. Bulletproof glass is generally rated based on the UL 752 standards developed for the purpose of testing and rating the bulletproof resistance of a material. Materials are ranked from “1” through “8” using a formula that takes into account both the bullet type and the number of shots the material can sustain before becoming compromised.
Bulletproof Glass Materials
In general, bulletproof glass is made of a combination of two or more types of laminated glass. While compositions vary, bulletproof glass must have at least one hard and one soft material in order to maintain the blend of elasticity and stability needed. These materials impact price.
Size and Shape of Glass
With bulletproof glass windows, doors, and storefronts priced by square foot in most cases, the dimensions of the area being covered dramatically impact final cost. In general, bullet resistant glass cost is higher for oval, circular, or custom-shaped windows compared to traditional square or rectangular windows because the cuts are more complicated.
Thickness is also a consideration because thicker glass is considered both more durable and more difficult to install. With thicknesses being anywhere from 19 millimeters to 89 millimeters, customers having bulletproof glass panes made and installed are looking at some big price variations depending on what they choose.

TYPES OF BULLETPROOF GLASS AND THEIR COST
Clients have four basic options to choose from when selecting bulletproof glass. In general, bullet resistant glass cost is calculated in square feet. Thickness, quality, and grade options within each glass category can also impact cost.
Insulated Ballistic Glass
Insulated ballistic glass is constructed with multiple glass panes separated by a space with sealed air or gas. In addition to providing ballistic protection, this option also delivers efficiency via an enhanced thermal barrier. The pros of insulated ballistic glass include energy efficiency, easy cleaning and maintenance, and strong natural light transmission. On average, insulated ballistic glass can cost between $75 and $60 per square foot.
Acrylic Bullet-Resistant Glass
Acrylic bullet-resistant glass is prized for its ability to stand up to long-term sun exposure. It also has low water absorption and good optical properties. While its impact resistance is far stronger compared to ordinary glass, it’s a much weaker option compared to ballistic glass. Pricing can range from $47 to $55 per square foot.
Laminated Glass
Laminated glass can be found for as low as $9 to $15 per square foot. This common type of safety glass is created by bonding two or more layers of glass together. Ideal for interior use, laminated glass often contains a plastic resin called polyvinyl butyral that is renowned for its durability, clarity, and ability to bond easily with other materials. When laminated glass is struck by impact, it will crack in a signature “web” pattern instead of shattering into pieces. In storm conditions, this can reduce the risk of flying glass shards harming people.
Polycarbonate Bulletproof Glass
On average, polycarbonate bulletproof glass can cost between $60 and $120 per square foot. Designed to be strong enough to stop a bullet without shattering, polycarbonate bulletproof glass is considered the most robust type of bulletproof glass available for commercial and residential properties.
