Air Barriers Meet NFPA 285 – Burning Issues

Air Barriers Meet NFPA 285 – Burning Issues

Presented by Peter Barrett and Marcus Jablonka, both of Dörken Systems, Inc. 

The relationship between the air barrier/water-resistive barrier and NFPA 285 (Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Wall Assemblies Containing Combustible Components) compliance is often misunderstood. We propose to add clarity by going beyond the standard misconception that one must consider NFPA 285 requirements only if the building is taller than 40 feet. While not necessarily new, the issues are broadly misunderstood, and assemblies not compliant with the building code are too often specified unknowingly.

Based on the authors’ in-depth synthesis and analysis of information from a wide array of sources and experts, they will examine in detail the effects of insulation and cladding choices as they relate to selection of the water-resistive barrier (WRB), as well as the membrane’s location within the wall system. This will be supported using real project detail drawings and specifications. In addition, manufacturer NFPA 285 compliance documentation, which can be difficult to interpret, will be examined for design and field use.
