A collaborative industry‐government research program was carried out at the National Research Council Canada (NRC) to develop new sound‐transmission‐class and fire‐resistance ratings for gypsum‐board protected walls. Forintek Canada Corp. and the Canadian Wood Council participated in the program on behalf of Canada's wood industry. As a result of that NRC research program, sound‐transmission‐class (STC) and fire‐resistance (FR) ratings were formulated for approximately 140 gypsum‐protected wood‐frame walls. Fire‐resistance ratings for the walls range from 30 minutes to 2 hours. Sound‐transmission‐class ratings range from 30 to 65. Sound‐transmission‐class and fire‐resistance ratings for approximately 90 of the wall designs appear in the 1995 edition of the National Building Code of Canada (NBCC). This paper highlights some of those STC and FR ratings and describes how they were derived from the data obtained through the research program.
