Ballistic Glazing for Municipal Buildings and Public Service Counters
Quick answer: Ballistic glazing is transparent, UL 752-rated material — laminated glass, polycarbonate, acrylic, or glass-clad polycarbonate — set in a matching rated frame to stop specified firearm threats. In municipal buildings it is used most often at public
Why Do Fiberglass Ballistic Panels for Walls Prevent Bullets From Ricocheting?
Ballistic performance does not end at the moment a wall stops a projectile. The interaction between the bullet and the barrier determines whether the impact is safely contained or if the projectile and its fragments risk ricocheting back into
How Do You Match the Capabilities of Bullet Resistant Doors to Active Threat Scenarios?
Bullet resistant doors should be specified with capabilities that match the active threat scenarios identified for a particular facility. Consider the difference between a classroom door and an entrance to a police facility. Both may require ballistic protection, but the anticipated weapon threats, frequency of use, access-control requirements, and consequences
Bullet Resistant Window Systems for Schools: What Meets Code and Survives Audit
Short answer: no US model building code mandates ballistic protection in schools. The International Building Code does not specify UL 752 levels directly, though certain occupancies may reference ballistic resistance performance criteria. What that means practically is that "meets code" for a school glazing scope is the wrong test —
Laminated Ballistic Glass vs. Polycarbonate vs. Glass-Clad Polycarbonate
Short answer: laminated ballistic glass delivers durability and optical clarity through alternating glass and plastic layers; polycarbonate delivers extreme impact absorption at low weight but scratches and weathers poorly; glass-clad
What UL 752 Level Should an Urban Commercial Office Specify?
Short answer: Level 1 is the baseline and the most commonly specified level for commercial office environments, because it addresses the 9mm handgun threat that defines the commercial risk profile.
UL 752 vs. NIJ vs. ASTM F1233 vs. HP White: Which Standard Applies to Your Project
Short answer: these are not competing standards measuring the same thing. UL 752 rates architectural ballistic products. NIJ standards govern personal protective equipment. ASTM F1233 evaluates security glazing against combined ballistic and forced-entry attack. HP
Security Window Film vs. UL 752 Ballistic Glazing: What Film Can and Cannot Do
Short answer: security window film and bullet-resistant glazing solve different problems. Film reinforces existing glass against impact, fragmentation, and forced entry. UL 752 glazing absorbs and arrests projectiles. Film cannot
