Why should air barriers meet NFPA 285?


Previous posts have explained NFPA 285 and specific code requirements necessitating NFPA 285 testing.  Sometimes we think that this type of testing is excessive and unnecessary.  The video below was taken of a high school in Michigan where only an air barrier over the exterior gypsum sheathing had been applied.  This air barrier material (by another manufacture) has not been tested in a NFPA 285 assembly.  The material is a synthetic polymer and does not contain any asphaltic properties.  As you watch the video, observe how quickly the fire propagates and the potential harm that could occur to the occupants.  Fire safety is extremely important and having the right air barrier material that satisfies the code will minimize the risks to the building tenants.
