ABSTRACT: As with many products, the building code regulates the use of wood in construction. Two broad categories separate materials: combustible and noncombustible. Codes limit the application of combustible materials on the basis of fire and life safety. The question then is, ‘‘Are there options available in the 2009 International Building Code for using wood in structural applications in lieu of noncombustible materials?’’ Fire Retardant Treated Wood (FRTW) provides that option. The 2009 IBC recognize FRTW for many applications where a noncombustible material is mandated. A few applications allow FRTW in lieu of 1-hour ratings.
