Cracks between walls, ceilings, and floors compromise the sound isolation of any room by allowing noise to penetrate into adjoining rooms. Simply adding Green Glue Noise Proofing Sealant to your soundproofing project can reduce noise transmission by 100 times or more. Green Glue Noise Proofing Sealant can be applied as easily as any standard calking material. It fits into a quart-sized calking gun and is applied along the edges and joints between floors and walls and ceilings and walls for maximum performance. Green Glue Noise Proofing Sealant can also be painted once dry. Green Glue Noise Proofing Sealant exceeds LEED green building requirements and is low odor. It can be easily cleaned while still wet with soap and water.
