How To Know Requirements for Bulletproof Glass

Maybe your business requires a higher level of protection than usual - a bank, a pawnshop, a 24-hour gasoline station. Or maybe you're just a very cautious person, and your own and your family's safety is of utmost importance for you (hey, sometimes it pays to be paranoid). One of the best things you can do with respect to heightening safety and security is by installing bulletproof glass in vulnerable areas, such as your car windows, or the cash desk at your business. So if you're looking into finding out more about bulletproof glass - such as its recommended dimensions and thickness - read on to find out more about this topic:

  1. How effective is bulletproof glass? Manufacturers refer to bulletproof glass with a more accurate term, "bullet-resistant glass," or "protective glass". That's because to date, there's no technology that could fully withstand an onslaught of bullets, especially from a high-caliber, large arms source. Typically, bulletproof glass provides impact-resistance against such tools as hammers, axes, and small-arms devices, and can realistically withstand one or more rounds of bullets.
  2. What makes up bulletproof glass? Polycarbonate glass, or more accurately, polycarbonate thermoplastic, is the main component of bulletproof glass. Different polycarbonate brands include Makroclear, Cyrolon, Tuffak and Armormax. Bulletproof glass typically comprises alternating layers of regular glass and polycarbonate material. This makes the glass much thicker and resistant to invasive materials than ordinary glass. With this composition, the glass will be able to absorb the impact of the bullet; so while the bullet may pierce an outside layer of the glass, the polycarbonate will stop it from going through to the final layer.
  3. How does bulletproof glass work? As mentioned above, bulletproof glass works by absorbing the energy of the bullet. Once a bullet hits the brittle exterior layer, that particular layer would shatter, working to absorb the bullet's impact. The next layers, which are more flexible, would stop the remaining energy of the bullet.
  4. What are the dimensions and thickness for bulletproof glass? The strength of the bulletproof glass would largely depend on its thickness and dimensions. Good thickness is at 2.8 to 3 inches (or 70-75 mm). However, there are some variations to this measurement. Some manufacturers create bulletproof glass at 55 mm. There are also manufacturers that categorize their products' thickness depending on your needs: an example is Pacific Bulletproof Company, which sets the following categories: Level 1, which is at 1.185 inches thick; Level 2, which is 1.4 inches thick; and Level 3, with more specialized thickness. Dimensions would depend upon your specifications. However, typical sizes are at 2 470 x 3 660 mm (maximum) and 250 x 200 mm (minimum).
  5. What are other related protective devices? Other similar protective devices available include bulletproof armor or tactical body armor, bulletproof jacket or ballistic vest, brass knuckles, etc. They work in basically the same principle, that of integrating highly-resistant materials over regular materials in order to provide comprehensively higher protection.
  6. Where can you buy bulletproof glass? You have several options for buying bulletproof glass; perhaps the most convenient way will be to purchase it online from such sites as, and

These are just some of the things you need to know about bulletproof glass, especially with regards to its workable dimension and thickness. Good luck!
