Titebond 28 Oz GREENchoice Acoustical Smoke Sound Sealant

This sealant is a non-flammable. latex-based product designed specifically for the reduction of sound transmission in wall partition systems. Its primary function is to achieve and maintain the specific STC (Sound Transmission Class) value of the system designed. Sealant remains permanently flexible and adheres firmly to wood or metal studs. concrete. gypsum board. and most other types of building substrates. Its unique formulation is non-staining and non-migrating. The sealant is used for unexposed applications at perimeter joints. floor and ceiling runners (either wood or metal). cutouts in gypsum board. veneer plaster systems. and other areas where a sound rated assembly is required.
