Green Glue Noiseproofing 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. It is non-hazardous, has practically no odor, and it resists drying out or cracking with age. Employ this acoustical sealant in conjunction with sound barriers, vibration isolators and other construction materials to effectively construct soundproof assemblies. No soundproofing job is complete without it.
Please note that Green Glue Noiseproofing Sealant is an acoustical sealant, not a glue, and should not be used as a substitute for glue or metal fasteners. As an acoustical caulk, it differs from standard caulk because it does not completely dry out over time. As such, it should not be used as a replacement for standard caulk, for example on exterior windows.
