Your business is your livelihood, so it does not hurt to take precautions to protect it. Gun violence is a real threat, especially in the USA, with statistics demonstrating that firearms cause the daily deaths of over 50 people¹. Bulletproofing can be used within a building to enhance its safety and shield against incoming projectiles. One material of note that can deliver this security is bulletproof glass, also defined as bullet resistant glass. Utilized in doors, windows, booths, and cases, this glass is crafted with layers of varying hardness. Those which are harder decrease the speed of the projectile. However those that are softer have the flexibility to take in the energy from the projectile. When these materials are used together, a bullet should be unable to pass through. The Underwriters Laboratories (UL) rating system can deliver insights on bulletproof glass, including on its strength and protective capabilities. Although there are 10 levels in total, this article will focus on level 3 bulletproofing, in particular level 3 bulletproof glass products.
What Is The UL Rating System Used For?
UL levels provide a clear indication of how well bulletproofing materials, such as bulletproof glass, can shield against projectiles. By placing this glass into 10 categories, with 1 being the lowest to 10 being the highest, the glass can be classified based on the projectiles it resists and its defensive capabilities. These levels make it easier to select the right type of glass for a specific application. For instance, a commercial business may need different types of glass to those used by the military.
Principal Facts About Level 3 Bulletproof Glass
Although bulletproof glass cannot stop all bullets and projectiles, choosing a specific UL level can help to understand the chance the glass has of not breaking during impact. Out of the 10 UL levels, level 3 bulletproof glass is not the highest. This means level 3 bulletproof glass is not the strongest, however it is the perfect barrier to use against three rounds of a .44 magnum. These rounds must have 1,350 – 1485 feet per second as a velocity when moving. Level 3 bulletproof glass can also be used as a defense against a .357 magnum or 9mm handgun, and even projectiles from rifles with reduced power.
Materials Used in Level 3 Bulletproof Glass
Like other levels of glass, level 3 bulletproof glass has a layered structure. The layers normally contain glass and a plastic, such as polycarbonate. They are laminated or merged through a bonding material or polyvinyl butyral. Be aware that the materials and layers forming level 3 bulletproof glass may differ depending on what is expected of the glass.
Thickness of Level 3 Bulletproof Glass
Again, the thickness of level 3 bulletproof glass will depend on what is required of it during use. With that said, its thickness is usually between a nominal 1.15 – 1.25 inches. When making a decision on the thickness of level 3 bulletproof glass, be mindful of how the glass could be impacted by it. Thicker glass will have more capabilities but it could become heavier and more difficult to see through it.
Benefits of Level 3 Bulletproof Glass
Level 3 bulletproof glass is extremely useful as a barrier, offering a defense to stop projectiles from stronger handguns. Additionally, it can serve as security to counter forced entry. This level of glass is a good choice for those looking to install a moderate means of defense without it becoming too expensive. Cost is something that can be an issue with glass that has a higher UL level.
The Uses of Level 3 Bulletproof Glass
Deciding upon a certain level of bulletproof glass will depend upon the risks it is expected to defend against. Stronger levels, those above level 3, are usually applied to areas requiring extensive security, like a cash vault. While these levels deliver additional protection, level 3 bulletproof glass would be better for incidents involving a handgun. This is because it can deliver the defenses required at a reasonable price. Examples of areas that utilize level 3 bulletproof glass include banks, schools, courthouses, and correctional facilities.
Take Your Time Deciding Upon Your Level of Bulletproof Glass
Many different levels of bulletproof glass exist. The choice you make between them will be based upon their application and the types of incidents they must shield against. No matter which level you select, be it level 3 bulletproof glass or something higher, utilizing bulletproof glass offers protection during an attack. Incorporate it into your security and it will have an impact, providing a barrier to prevent the worst from happening.
