Specifications
• The International Building Code requires walls, partitions, and floor/ceiling assemblies separating dwelling units from each other or from public or service areas to have a sound transmission class (STC) of no less than 50 for airborne noise when tested in accordance with ASTM-E90.
• Sound Seal 90 Acoustic Draft, Smoke, and Acoustical Sound Sealant has been tested as part of an ASTM-E90 wall assembly increasing the integrity from a 39 STC (with no perimeter sealant) to a 52 STC rated wall assembly after acoustic sealant installation.
