Fire-Resistance and Sound-Insulation Ratings for Walls, Partitions, and Floors. Technical Report on Building Materials No. 44
In the construction of buildings, particularly those of the residential type, partition and floor constructions should provide safety to life from the spread of fire and should reduce transmitted sounds and objectional noises to inaudible levels. The ability of a construction to prevent the spread of fire may be expressed in periods of fire resistance, that is, the time for which the construction may be exposed to a fire of a standard intensity without collapse, passage of flame, or the transmission of heat sufficient to cause ignition of combustible material. The sound insulation may be measured by the decrease in intensity of the sound as it travels through the wall. This paper gives the fire-resistance and sound-insulation ratings of walls, partitions, and floors. Most of the fire-resistance ratings are based on tests made at the National Bureau of Standards. Some are based on tests made at Underwriters' Laboratories or at Ohio State University. All of the sound-insulation ratings are based on tests made at the National Bureau of Standards. The detailed results of many of the fire tests of wood- and metal-framed partitions have been published in Building Materials and Structures Report BMS 71, 'Fire Tests of Wood- and Metal-Framed Partitions.' The details of the sound-insulation tests are given in Building Materials and Structures Report BMS 44, 'Sound Insulation of Wall and Floor Construction', and Supplemental. Since the present objective is to present information of value in selecting or designing constructions suitable for use as subdivisions between family units in multiple dwellings, those having fire-resistance ratings of less than 1/2 hr are not included. The ratings are applicable to walls and floors in other types of buildings.
