There has been a lot of chatter recently about the “new” residential fire protection requirements in the U.S. If this is a new topic for you, or you simply want to understand what is going on, download the following IB technical bulletins:
TB-IJ-6, Fire Considerations for Residential Wood I-Joist Floors (U.S.)
TB-IJ-11, Fire Protection Requirements for Floors under IRC (U.S. Residential Building Code)
These documents have been updated May 2014 with additional reference material. Bulletin 6 is a one-pager, and bulletin 11 is a two-pager. Depending on your audience, one may be more appropriate than the other.
