Build in fire safety with the 2015 NFPA 220 -- your source for the ratings required for exterior walls, columns, floors, ceilings, and roof assemblies.

Make informed construction classifications based on the 2015 NFPA 220: Standard on Types of Building Construction. Requirements define construction assemblies based on the combustibility and the fire resistance rating of their structural elements. NFPA 220 is an extract document of Section 7.2 NFPA 5000®: Building Construction and Safety Code®.

Consistent with the 2015 editions of NFPA 5000, NFPA 90A, and other NFPA® codes and standards.

Construction type designations, including Type I (332) and Type IV (2HH), are described in this edition, which is updated to reflect current methods and technologies. The 2015 NFPA 220 includes extracted language from the 2015 NFPA 90A: Standard for Installation of Air Conditioning and Ventilating Systems, among other revisions.

Architects, engineers, AHJs -- and anyone responsible for making construction classifications -- will work confidently with the specific limits outlined in NFPA 220.
