Now subject to NFPA 285 testing per the International Building Code, foam plastic insulation, combustible exterior claddings, and water-resistive barriers must demonstrate limited fire propagation.
Decision Tree
Is my FPIS Wall Assembly Required to Comply?
This decision tree will help you determine whether the building code actually requires the assembly to be NFPA 285 compliant. This decision tree is based on the 2012 and 2015 versions of the International Building Code and applies to FPIS wall assemblies ONLY.
