Blast Mitigation Series

Overly’s Blast Mitigation (BMD) series blast and pressure resistant openings are lightweight, 1-3/4” thick personnel size doors that provide the appearance and user friendly features of standard hollow metal type doors.


These openings meet the requirements of Unified Facilities Criteria (UFC) 4-010-01, “DOD Minimum Anti-Terrorism Standards for Buildings.” This criteria requires all exterior doors to be designed in accordance with ASTM F2927-12, “Standard Test method for Door Systems Subject to Air blast Loadings”


To accommodate these requirements, Overly has designed and tested several opening sizes and configurations to determine the door response damage category at various air blast pressure loads and impulses. These results can be seen in the chart below.

If fire ratings are required, flush, non-vision light BMD openings can be UL Labeled in accordance with UL Standard for Safety 10C, “Positive Pressure Fire Tests of Door Assemblies,” when project parameters meet the construction requirements of our UL Procedures.
