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