Abstract

Fire resistant (FR) assemblies are key components of building a life safety design. These assemblies are typically required to divide buildings into smaller compartments so that, should a fire start, it will remain confined for a sufficient period to allow evacuation and arrival of fire fighting personnel. Properly installed and maintained FR construction has a long history of performance in both saving lives and limiting fire related property damage. This presentation provides an overview of the process used to develop FR assembly ratings and listings where a gypsum wallboard is a key assembly component. The discussion includes the test methods and standards required by model building codes, the process used by designers and manufacturers to obtain design certifications, and how these designs are intended to be applied in the field. There are often occasions where a basic FR assembly may need to be altered to improve performance not directly related to fire resistance. This frequently includes addition or changes in materials or other aspects of a design to improve acoustical performance. However, all changes to FR assembly designs have the potential to change the fire resistance of the assembly. The process required to obtain acceptance of design modifications is discussed.
