In an era where safety and security are top priorities, bullet resistant glass has become essential across a wide range of industries—from banks and military installations to retail storefronts and residential buildings. But not all bullet resistant glass is created equal. Different levels of protection are required depending on the threat environment, and that’s where understanding bullet resistant glass levels becomes crucial. At Shottglass , we specialize in advanced ballistic glazing solutions that meet rigorous safety standards while offering clear visibility and aesthetic flexibility. In this guide, we’ll walk you through the key levels of bullet resistant glass, the testing standards behind them, and how to choose the right level for your application. What Is Bullet Resistant Glass? Despite the term "bulletproof glass" being widely used, no glass is completely bulletproof—only bullet resistant to varying degrees. Bullet resistant glass , also known as ballistic glass, is designed to absorb and disperse the energy of a bullet, preventing penetration and minimizing the risk of injury or property damage. The construction typically includes layers of polycarbonate, glass, and proprietary interlayers laminated under high pressure. At Shottglass , we use multi-layered compositions engineered to balance performance, clarity, and thickness, ensuring both protection and usability. Bullet Resistant Glass Levels Explained Bullet resistant glass is categorized into levels based on the type of ammunition it can withstand. The most widely used standards are from Underwriters Laboratories (UL 752) and National Institute of Justice (NIJ) . At Shottglass , we manufacture bullet resistant glass rated from UL Level 1 up to UL Level 8 , meeting or exceeding industry benchmarks. UL 752 Levels: Level 1: Resists 9mm full metal jacket rounds at 1175 ft/s. Ideal for convenience stores, residential doors, and low-risk areas. Level 2: Stops .357 Magnum jacketed soft points at 1250 ft/s. Often used in schools, pharmacies, and retail settings. Level 3: Designed for .44 Magnum semi-jacketed hollow points at 1350 ft/s. A popular choice for banks, guard booths, and cashier enclosures. Level 4: Offers protection against .30 caliber rifles (M1 rifle) at 2540 ft/s. Typically found in government buildings or sensitive security zones. Levels 5–8: These levels defend against higher-caliber rifles like 7.62mm NATO or .308 Winchester. Frequently used in military applications, embassies, and law enforcement facilities. Each level is tested for multiple shots to ensure consistent performance under real-world conditions. How Is Bullet Resistant Glass Tested? The UL 752 testing process involves firing specific ammunition types at the glass from a controlled distance. The goal is not just to prevent penetration but also to control spall—the glass fragments that may fly off the non-impacted side. To pass, no bullet should penetrate, and no spall should endanger a person on the protected side. Shottglass’s ballistic glazing products are tested under these exact standards in certified labs. We also offer custom ballistic simulations and reports for high-risk clients needing tailored solutions. Shottglass Bullet Resistant Glass Solutions At Shottglass , we go beyond basic compliance.

Choosing the Right Bullet Resistant Glass Level Selecting the right level of bullet resistant glass depends on a thorough threat assessment . Here are some guiding principles: Retail stores or lobbies : Levels 1–2 are usually sufficient to deter handguns and reduce smash-and-grab risks. Banks or pharmacies : Level 3 offers higher assurance against common handgun threats. Police stations or government buildings : Level 4 and above offer necessary defense against high-powered rifles. Military or tactical facilities : Levels 5–8 are essential for extreme ballistic scenarios.
