NFPA 221 is an integral resource for professionals working in construction, architecture, engineering, manufacturing, insurance, risk management, and other industries. The standard provides anyone involved in building construction with comprehensive criteria for the proper design and construction of high challenge fire walls, fire walls, and fire barrier walls used to help protect lives and property from fire.

Fire moves fast, and just a few extra seconds can make a big difference when it comes to reducing damage and helping save lives. Fire wall assemblies offer an effective means of slowing the spread of fire.

NFPA 221, Standard for High Challenge Fire Walls, Fire Walls, and Fire Barrier Walls, covers general requirements for fire resistance ratings, performance-based design, and other considerations for high challenge fire walls, fire walls, and fire barrier walls, including protection of openings and penetrations.
