Recent code changes surrounding exterior walls, combined with needs for energy-efficient (green) construction, has led to a greater focus on compliance with NFPA 285, Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components. Historically, the acceptance of wall systems involved a fairly complex review of building code interpretation, evaluation reports (if available), individual component manufacturer's test reports, engineering analysis, and application of the manufacturer's installation instructions. This session will discuss UL's new certification categories for Exterior Wall Systems & Components, and demonstrate how this new approach meets the needs of manufacturers, architects, specifiers, and Code Officials for an accessible, up-to-date method of determining compliance of exterior wall systems evaluated to NFPA 285.
