This report by the U.S. Department of Housing and Urban Development Office of Policy Development and Research investigates regulatory requirements, available test data, and typical practices relating to acoustics and fire protection of cold-formed steel framing. The intention is to give an overview of current regulations, as well as a "snap shot" of available fire and acoustic cold-formed steel assemblies. This document starts by providing an overview of fire and acoustic requirements of cold-formed steel assemblies and the characteristics of such assemblies as related to fire and acoustic performance. A detailed description of current building codes and building code requirements for the fire protection and acoustical insulation of cold-formed steel assemblies follows. A comprehensive list of tested fire- and sound-rated assemblies is provided. Finally, recommendations are given to direct future tests and research.
