New Green Glue for the Soundproofing Industry

Acoustical Solutions has introduced Green Glue. Green Glue is a liquid, waterborne, sound damping compound. It is used in between sheets of drywall, subflooring or other building materials. It is tolerant to real-world application conditions and carries almost none of the burden of precision required by many soundproofing systems.

The best application for Green Glue is between sheets of drywall, OSB or Plywood over the main part of a wall, floor or other structure. Green Glue will not be effective as a paint or coating. Green Glue is non-toxic with no mixing required. For walls, floors and ceilings, this product drastically reduces impact and airborne noise. It can also be used in commercial environments, new construction or remodeling of an existing space as well as home theaters, and recording studios.

In a constrained layer damping system, sometimes referred to as CLD, a damping material is sandwiched between two other materials. For example, Green Glue sandwiched between two layers of drywall. Sound damping occurs when the viscoelastic center of the 'sandwich' is sheared. The shearing pulls and stretches on the sound damping material. Under these conditions, the unique polymeric construction of Green Glue very efficiently converts this mechanical energy to heat. The vibration energy is not isolated; it's dissipated and removed.

Green Glue comes in 29 oz. tubes. It can be applied with any quart size caulk gun, available at most hardware and building material stores. It is very fast and easy to apply, no special skills whatsoever are required. Recommended application is two tubes of Green Glue per 4' x 8' area or two tubes per standard sheet of drywall. Each case of Green Glue covers about 192 square feet, or 128 square feet if used at the three tubes coverage rate.
