CSSBI FPB-27: Fire Protection Bulletin #27: Fire Resistance and Acoustic Ratings for Cold-Formed Steel Framed Floor Assemblies

CSSBI FPB 27 presents fire resistance and acoustic ratings for cold formed steel framed floor assemblies, based on testing conducted by the National Research Council of Canada. It provides essential performance data for assemblies using cold formed C section steel joists, commonly used in small building construction up to six storeys. The bulletin supports compliance with building codes across Canada by offering generic ratings that help designers and builders meet minimum safety and acoustic standards.
