3M 7100038650 Smoke and Sound Sealant 20 Fl Oz

Product Description

The 3M 7100038650 is a flexible latex sealant formulated to reduce airborne sound transmission and block smoke migration through construction joints and through-penetrations in non-fire-rated wall and floor assemblies. It functions as a draftstop to limit unwanted air movement and provides a barrier against dust and other airborne particulates. Supplied in a 20 fl oz sausage-style cartridge and finished in white, this product is suited for commercial and residential construction applications where acoustic control and smoke containment are required in non-fire-rated assemblies.

This sealant is applied by insulation contractors, general contractors, and specialty trade installers working on interior partition walls and floor penetrations. Typical installations include sealing around electrical conduit, pipe, and duct penetrations through non-fire-rated assemblies where sound attenuation and smoke draftstopping are project requirements. The sausage-pack format is compatible with standard sausage-style caulk guns commonly used on commercial job sites.
