Some corporate entryways are constructed entirely from bulletproof glass and framing their pleasant vestibules are actually man traps ready to lockdown at the push of a button. For example, many government buildings have a high-level forced entry-rated blast and bullet-resistant glass reinforcing every exterior window, plus ballistic fiberglass in every interior and exterior wall. ![]() Obviously, bullet-resistant glass systems and security can go well beyond what you see at the bank or ticket counter. In summary, a mid-range system (such as this theoretical truck stop, a small bank branch, or a corner store) is going to run around $15,000 to $25,000 (not including installation). Many also elect to install “sliders.” These windows can be opened during low-crime, high-traffic periods and then locked down after the sun sets or in an emergency, allowing for extra flexibility for employees. Most gas stations and convenience stores favor natural voice communication rather than electronic intercoms (at least for interior applications). Then there’s the aspect of safe communication with customers. Each hardened point-of-payment will be accessible through a bulletproof door, and the business owners may choose to use an electronic keypad/buzz-through access system, as this mitigates the risks that come with trying to keep track of physical keys. Additionally, ballistic fiberglass will be needed to reinforce the counters, and deep steel deal trays should be integrated into the countertops. ![]() At a minimum, each register needs to be enclosed in a bulletproof glass booth. The cost of this type of system can vary depending on the store’s security needs and the degree of flexibility they’d like in their system. These retailers usually have at least two registers and are looking for both exterior and interior bullet-resistant glass. For example, consider a 24-hour gas station-the sort of “truck-stop oasis” that includes a well-stocked convenience store. ![]() More comprehensive barrier systems (like those used in retail or banking) demand a greater degree of customization. Including shipping and handling, this sort of minimal system will cost at least $7,000 to $10,000 (not including installation).Ī Mid-Range Bullet-Resistant Barrier System Local contractors can often do installation work, although most bulletproof companies will send their own installation team for an additional fee. These ship as pre-fabricated, built-to-order components that will need to be installed on-site. This type of system would include a bullet-resistant glass transaction window with an integrated communication system and cash tray, ballistic fiberglass to reinforce the surrounding walls, and perhaps a simple, all-steel bullet-resistant door and frame. On one end of the spectrum is a minimal, straight-forward system-something suitable for a stand-alone ticket window, small retail setting, or after-hours transactions. That being said, here are some guidelines for what price ranges you can expect from different bulletproof solutions. Because these systems are customized for a wide variety of security needs, their costs can vary widely. This is easy to do with ovens and cars, but challenging for bullet-resistant glass security systems. We also find it in optical instruments like lenses for telescopes, microscopes, and eyeglasses, and as glassware like drinking glass, laboratory flasks, test tubes, manometers, and bowls.Before buying a big-ticket item, most of us take a few minutes to do a little Googling and get a sense of the price landscape. ![]() We can see glass framed in windows, bookshelves, and picture frames. Glass has so many applications that we now see it used almost everywhere. We can also subject glass to various processes like heat-treatment (to produce tempered glass panels and fire glasses), lamination (to produce laminated glasses for windshield and window safety glasses), sandblasting or etching (to produce frosted glasses), and so much more. This can make them a bit harder to break than regular glass (or easier if you want to break through glass like a Hollywood actor). You can also add some other chemical compounds, like magnesia, alumina, potash, iron oxide, and lead oxide, which, depending on their proportions, can also improve the glass's strength and durability. Incorporating boron trioxide into the mix will yield a borosilicate glass which is more thermal shock-resistant than regular soda-lime glass.
