Understanding Ballistic-Resistant Glazing Requirements
Ballistic glazing is rated against test standards such as UL 752, and the rating always belongs to the exact tested assembly. Here's how the levels work and how they fit Delaware school projects under Title 14 §2306.
What “Ballistic Resistant” Actually Means
- Ratings come from recognized test standards such as UL 752 and NIJ; a rating describes ballistic resistance for a specific tested assembly, not absolute invulnerability.
- A rating belongs to the complete tested assembly: glass type and thickness, any treatment, film layers, and framing — not to any single component.
- Delaware Title 14 §2306(b)(2) lists ballistic-resistant glass or material as one option for covered visitor-screening areas; it does not name a required test level.
How UL 752 Levels Work
- UL 752 defines multiple levels tied to specific ammunition and shot patterns, from handgun to rifle threats.
- The appropriate level for a project is a design-team decision based on the threat assessment — no level is mandated statewide.
- Higher levels drive glass thickness, weight, framing, and cost; the frame and anchorage must be engineered for the rated glazing.
Where Rated Glazing Is Typically Evaluated
- Secured vestibules, reception sidelights, and visitor-screening office glass — the areas §2306(b)(2) names for qualifying projects.
- Other locations only where the project's risk and design review calls for them.
Specifying Ballistic Glazing in a Real Building
- Framing, anchorage, and structural requirements sized to the rated assembly.
- Manufacturer test documentation for the exact configuration being installed.
- Coordination with security film at adjacent, non-rated openings.

Frequently Asked Questions
What UL 752 level does Delaware require for schools?
Delaware Title 14 §2306 does not name a UL 752 level. It lists ballistic-resistant glass or material — or security film — as options for secured vestibule, lobby, and visitor-screening office areas in qualifying projects. The specified level, if ballistic-resistant material is chosen, is a project-specific decision made by the design team and confirmed through the applicable state review process.
Is C-Bond considered ballistic glazing?
C-Bond BRS is a ballistic-resistant system in which a specified glass type and thickness, C-Bond glass treatment, and a minimum number of film layers are engineered together. Any ballistic rating belongs to the exact configuration documented in the manufacturer's performance data — not to the treatment or film alone, and not to untested combinations.
