Product Details

OSI® GreenSeries™ Draft & Acoustical Sound Sealant is a white, non-flammable, low VOC, latex-based sealant specially designed to reduce sound transmissions and drafts in all types of wall systems where a sound-rated assembly is required. Its primary function is to achieve and maintain the specific STC (Sound Transmission Class) value of the system designed. This paintable sealant remains flexible and adheres firmly to wood, metal studs, concrete, gypsum board and most other common building materials.

OSI® GreenSeries™ Draft & Acoustical Sound Sealant exceeds LEED green building requirements, is low V.O.C., and is low odor. It can be easily cleaned while still wet with soap and water.

Use it for exposed and unexposed applications at perimeter joints, floor and ceiling runners, cutouts in gypsum board, veneer plaster systems and other areas where a sound rated assembly is required. This sealant can also be applied or buttered around all electrical boxes and outlets, cold air returns, heating and air conditioning ducts and other equipment penetrating wall surfaces for increased acoustical performance.
