Green Glue Soundproofing Sealant

Green Glue Sealant seals cracks and gaps to prevent unwanted noise from escaping a room. Like cracks in armor, the best soundproofing strategy will fail if you leave cracks and other gaps in a wall, floor or ceiling uncovered. Green Glue Sealant minimizes what is called “flanking noise” and helps with the newly created ASTC rating (Apparent Sound Transmission Class). It is non-hazardous, has practically no odor, and it resists drying out or cracking with age. Employ this acoustical sealant in conjunction with Green Glue Compound, Mass Loaded Vinyl, Resilmount Sound Clips and other construction materials to effectively construct soundproof assemblies. No soundproofing job is complete without it.


It takes just minutes to apply Green Glue Noiseproofing Sealant along edges and cracks. It dries completely in 48 hours.


No training is necessary to use Green Glue Sealant – you can apply it in the same fashion as standard caulking material. The sealant comes in 28-ounce tubes that fit into quart-sized calking guns. Cleanup is simple with just soap and water, even when wet. Once dry, you can paint over the sealant. See below for a how to video on application of Green Glue Sealant.


Adding Green Glue Sealant to your soundproofing project can reduce noise transmission through floor ceiling assemblies, as well as squeaking caused by settling floors. Green Glue Sealant exceeds LEED green building requirements and has been independently tested by Underwriters Laboratories for fire safety and environmental impact.
