Green Glue is a constrained layer damping system, which as a damping material is sandwiched between two other rigid materials such as two sheets of drywall or any other porous building material. Damping occurs when the viscoelastic center of the "sandwich" is sheared. Green Glue works effectively against any impact or airborne noise control problem.
Green Glue can be used over any existing wall, floor or ceiling by simply adding another layer of material. No rolling, painting or troweling is necessary. Just open the tube and apply in a random pattern. With a fast and easy installation, anybody can soundproof a room with Green Glue.
