As an Architect, for over 30 years I have generally avoided, and directed my Engineers to avoid using open web wood trusses in Type V Construction with a NFPA 13 sprinkler system. This philosophy has been based on the challenges posed by the NFPA 13 requirements for concealed combustible spaces. I have always maintained an open web wood truss is similar to "Double joist Obstructions" (2013-NFPA 13 Section 10.2.6.1.5.1and Figure 10.2.6.1.5) and if the distance between the chords was more than 6" sprinklers were required. Some might say 2013-NFPA 13 Section 9.2.1.6 applies, not requiring sprinklers, I say NO, this section references "joists" NOT trusses. Can one of the "sprinkler guru's" confirm my Philosophy has been correct for 30 years.
Thanks in advance,
