Understanding UL 752 Ballistic Window Ratings: What You Need to Know
When it comes to bullet-resistant windows, understanding the UL 752 ballistic rating system is essential. Whether you are securing a government building, financial institution, or high-risk facility, choosing the right ballistic-rated windowcan make all the difference in safety and protection.
What is UL 752?
UL 752 is a standard developed by Underwriters Laboratories (UL) to classify the ballistic resistance of materials such as windows, doors, and panels. The system consists of 10 levels, each tested against specific types of firearm threats. This rating helps architects, security experts, and facility managers choose the appropriate level of protection.
UL 752 Ballistic Protection Levels
Below is a breakdown of the 10 ballistic levels under UL 752:
Low-Level Threat Protection
-
Level 1 – 9mm Full Metal Jacket (FMJ), 124 grain at ~1,175 fps
Common applications: Cashier windows, convenience stores, low-security offices. -
Level 2 – .357 Magnum Jacketed Soft Point (JSP), 158 grain at ~1,250 fps
Common applications: Law enforcement offices, financial institutions, medium-security buildings. -
Level 3 – .44 Magnum Lead Semi-Wadcutter (SWC), 240 grain at ~1,350 fps
Common applications: Bank teller windows, courtrooms, detention facilities.
Medium-Level Threat Protection
-
Level 4 – .30-06 Rifle M2 Armor-Piercing (AP), 166 grain at ~2,850 fps
Common applications: Military buildings, embassies, critical infrastructure. -
Level 5 – 5.56mm M193, 55 grain at ~3,250 fps
Common applications: High-risk government facilities, police stations. -
Level 6 – 7.62mm/.308 Winchester, 150 grain at ~2,750 fps
Common applications: High-security commercial and law enforcement facilities.
High-Level Threat Protection
-
Level 7 – 5.56mm M855 (Green Tip), 62 grain at ~3,150 fps
Common applications: Police armories, military headquarters. -
Level 8 – 7.62mm NATO (AP), 150 grain at ~2,750 fps
Common applications: Critical government infrastructure, secure checkpoints. -
Level 9 – .50 Action Express, 325 grain at ~1,475 fps
Common applications: High-profile security environments, executive protection. -
Level 10 – .50 BMG (Armor-Piercing), 700 grain at ~2,925 fps
Common applications: Military bunkers, nuclear facilities, sensitive installations.
How to Choose the Right UL 752 Ballistic Window
When selecting a ballistic window, consider the following factors:
-
Threat level: Assess the potential firearm threats in your location.
-
Application: Financial institutions, government buildings, schools, and private properties may require different protection levels.
-
Material composition: Bullet-r
