UL 752 Bullet-Resistant Design Guide for Architects: Levels, Specification, and Cost Resources
Architects and specifiers working on bullet-resistant openings need four things: the correct terminology and standard (UL 752, not "bulletproof"), a specification sequence that starts with a threat assessment, level-by-level technical data on threats and panel thickness, and a realistic view…
What Ballistic Protection Rating Do I Need? Matching Threats to the Right Fiberglass Panel
Quick Summary for Architects Choosing a ballistic protection rating means matching the assessed threat — the specific weapon, ammunition, and number of shots — to the corresponding UL 752 level. Handgun threats (9mm, .357 Magnum, .44 Magnum) map to UL…
