Embassy Security: Meeting ISC Requirements with Window Film

Posted by The Window Place USA on Apr 9th 2026

U.S. embassies and diplomatic facilities around the world face persistent security threats. The Interagency Security Committee (ISC) establishes the physical security criteria that all federal facilities — including diplomatic posts — must meet. Window film is a proven, cost-effective solution for meeting ISC glazing requirements.

ISC Security Design Criteria

The ISC establishes Facility Security Levels (FSL) ranging from Level I (lowest risk) to Level V (highest risk). Each level prescribes specific physical security measures, including glazing protection requirements.

Why Window Film for Embassies

Traditional approaches to embassy glazing security — laminated glass replacement or blast-resistant window systems — are extremely expensive and disruptive. Window film offers compelling advantages:

  • 75% cost savings compared to laminated glass replacement
  • Zero operational disruption — Install during normal business hours
  • Rapid deployment — Days instead of months
  • Dual benefit — Security + solar control in a single product
  • Worldwide availability — Ships to any diplomatic post

Blast Mitigation Performance

Solar Gard Armorcoat security films have been tested and certified under GSA-TS01-2003, the accepted blast testing standard for federal facilities:

  • Armorcoat 8-Mil: Retains glass fragments under moderate blast overpressure. Suitable for FSL III facilities with conventional standoff.
  • Armorcoat 14-Mil: Maximum fragment retention and forced-entry resistance. Required for FSL IV–V facilities and reduced standoff scenarios.

Forced Entry Resistance

For diplomatic facilities, forced entry is a critical threat vector. Security film dramatically increases the time required to breach a window:

  • Untreated glass: Breached in 1–3 seconds
  • 8-Mil security film: 15–30 seconds of delay
  • 14-Mil security film: 30–60+ seconds of delay
  • 14-Mil + wet-glaze attachment: 60+ seconds, prevents glass from being pushed inward
