Safeguard people and property by designing and constructing rated wall assemblies using the 2018 edition of NFPA 221.

Protect building occupants, limit property damage, and help fire fighters do their jobs safely and effectively with the 2018 edition of NFPA 221: Standard for High Challenge Fire Walls, Fire Walls, and Fire Barrier Walls.

This important Standard helps you construct fire walls and fire barrier walls to keep fire from spreading.

NFPA 221 helps you understand the requirements for fire rated walls in order to protect certain occupancies or hazards. Of vital importance to architects, engineers, and anyone involved with building construction, it identifies and provides a focus to differentiate between types of fire walls. The Standard presents comprehensive requirements for the design and construction of all types of rated wall assemblies including:

• High challenge fire walls
• Fire walls
• Fire barrier walls
• Protection of openings and penetrations

Update to the new, user-friendlier 2018 edition featuring:

• Clarified design load requirements
• A new section that allows use of the performance-based design of walls method from ASCE/SEI 7, Minimum Design Loads for Buildings and Other Structures
• Added Annex material that provides testing options in areas where there is potential for hydrocarbon fuel fires
• Reference document updates
• ASCE definitions reprinted with permission from ASCE

NFPA 221 is a critical resource for AHJs, engineers, architects, and construction industry professionals.
