STI Smoke & Sound sealant is a high-quality acrylic latex sealant designed for sealing through-penetrations (such as pipes, conduits, cabling, busways, openings), membrane penetrations (such as p-traps and outlet boxes) in smoke-rated walls.
STI Smoke & Sound sealant is available in a single grade that has excellent caulking properties as well as high build properties on vertical or overhead surfaces. This single grade may be caulked (standard cartridge or bulk loaded), knifed, or troweled. In addition, STI Smoke & Sound contains no PCBs, nor asbestos.
STI Smoke & Sound sealant is used for smoke control where stopping the passage of smoke is necessary such as in smoke-rated walls; for noise control where reducing the transmission of sound through wall openings is necessary to help ensure occupant privacy and a peaceful environment; for infectious/dust control where reducing the transmission of dust and other airborne particulates through wall openings is necessary.
