F2415 (Standard Guide for Secure Building Envelope)

F2415 is a standardized guideline that outlines best practices for designing, constructing, and maintaining secure building envelopes— the outer layer of a building that protects against intrusion, attack, or environmental threats. It covers aspects like using strong materials, proper installation techniques, and ongoing maintenance to ensure safety and security. The goal is to help architects, builders, and facility managers create buildings that resist unauthorized access, withstand environmental hazards, and support operational security, all while maintaining functionality and safety for occupants.
