Use of combustible building materials in wall assemblies increases the risk of fire in the built environment. The relationship between the weather barrier and NFPA285 compliance is often misunderstood. This course will cover the basics of the NFPA 285 test standard and the building code sections relevant to weather resistive barriers. It will also address the basics of test wall designs, including cladding, insulation, etc., how wall systems that include weather resistive barriers are analyzed for engineering evaluations and compliance strategies.

Learning Objectives:

1. Learn the basics of NFPA 285 and its role in wall assembly design.
2.  Review the building code requirements related to weather-resistive barriers (WRBs).
3.  Explore the basics of NFPA 285 test wall designs, including claddings, insulation types, and WRBs.
4. Understand how weather-resistive barriers are analyzed for engineering evaluations and compliance.
