1.1 This practice provides information for the use of sealants to reduce sound transmission characteristics of interior walls, ceilings, and floors by proper application of sealants to joints, voids, and penetrations normally found in building construction, which are commonly referred to as airborne sound flanking paths.

1.2 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.

1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.4 This standard does not purport to address fire stopping or safing requirements for joints, voids, and penetrations through fire-rated wall, ceiling, and floor assemblies. Additional requirements may be necessary for fire-rated assemblies to meet the applicable building code provisions.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


4.1 Walls, ceilings, and floors in building construction with improperly sealed joints, voids, or penetrations will not achieve the desired sound transmission loss. Proper sealing of joints, voids, and penetrations will increase sound transmission loss by reducing airborne sound flanking paths.
