What is Green Glue?

Green Glue is a water-based, viscoelelastic damping compound, with performance that is higher than any product of its type. It dampens air and structure borne sound and can be used in virtually any drywall wall or ceiling assembly. Green Glue can also be used in plywood and OSB assemblies.

Sound travels as a wave through the air. The waves hit a wall or ceiling and the energy becomes structure-borne. Unless the wall or ceiling material is damped, the vibration will travel through the building framing and exit somewhere else as sound again.


How does it work?

In a constrained layer damping system, sometimes referred to as CLD, a damping material is sandwiched between two other (usually stiff/center of the "sandwich" is sheared rigid) materials. For example, Green Glue sandwiched between two layers of drywall. Damping occurs when the viscoelastic center of the "sandwich" is sheared (see left).

When bent, shear forces pull and stretch on the 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 gone.

Green Glue is extremely easy to use – No special trades
or training required. Ideal for DIY applications.

Soundproofing has never been so easy !




* For many years Mass Loaded Vinyl has been recognized as one of the key ingredients or tolls available for effective soundproofing. Used for soundproofing rooms, walls or ducts, it an easy to use "Soundproofing Barrier" treatment. Click here for Mass Loaded Vinyl.

* Noise barriers have been made of a number of materials over the years. There are concrete noise barriers, wood noise barriers and vinyl noise barriers.

* Vinyl is being proven to be the material of choice for its good looks, longevity and acoustic performance not to mention its more cost effective than all the other materials.
