This course explains the NFPA 285 test method, its origin, its procedures, when it is required, and design considerations necessary to comply with it. The course explains the fire/life safety objective of NFPA 285. Selected sections of the
International Building Code are reviewed to identify the types of construction and circumstances that require NFPA 285 compliance. The criteria in ASHRAE 90.1 for continuous insulation and air/water resistive barriers are reviewed and
identified as contributors to the rise of NFPA 285 requirements. To understand the key wall assembly layers that determine compliance, the course reviews insulation, air/water resistive barriers, and exterior cladding options. Design practices will be improved by familiarizing attendees with information sources such as manufacturer design guides, proposed code changes, engineering analysis and the public database discussion.
