Data File: APA Rim Board in Fire Rated Assemblies
Data File
To slow or prevent the spread of fire, building codes require fire-resistant or fire-rated assemblies in certain locations, occupancies and types of buildings. When fire-rated walls or floor/ceiling assemblies are required, a fire barrier over the walls is typically necessary to prevent flames from escaping the confinement provided by the wall or ceiling assembly.
This publication is designed for: builders, contractors, code officials, inspectors, fire marshals
APA performance-rated rim boards are manufactured and tested under the requirements of ANSI/APA PRR 410 or APA PRR 401. This publication provides examples of rim board assemblies that will achieve certain fire resistances.
Key sections include:
End wall configuration base assembly
Single wall configuration base assembly
Double wall configuration with load transfer base assembly
Double wall configuration with no load transfer base assembly
