The sound insulations of metal-framed partitions having structural loadbearing properties
Abstract
The sound insulations were measured of several single and double leaf partitions. The partitions had metal frames and were capable of supporting significant structural loads. The purpose of the work was to design structural partitions that were cheaper to build than the existing masonry walls used for the construction of large studios. For some of the double leaf tests, one of the leaves was blockwork and the other was metal-framed, for the remainder of the double leaf tests, both leaves were metal-framed. Each of the partitions tested was suitable for use in different types of studio construction. The addition of glass wool insulation batts to the cavities of the partitions resulted in large increases in the measured sound insulations. The glass wool damps the motion of the boards and absorbs sound that has been transmitted into the cavities. The levels of sound insulation achieved from the partitions should be adequate for certain types of low cost studio construction. The partitions are considerably lighter than masonry walls. Therefore, the loadbearing requirements of the surrounding building will be reduced. Provided that the reductions in sound insulations are acceptable, the potential cost savings resulting from the use of lightweight structural partitions rather than masonry walls are very large.
