How does Green glue work to reduce sound?
One thing you should keep in mind is that Green Glue doesn’t act as a sound deadener, sound diffuser or sound absorber. Instead, it was designed to stop sound and vibration from traveling between rooms, and to convert sound energy and noise into heat, especially when you apply it within two or more stable layers.
What is green glue noiseproofing?
Green Glue Noiseproofing Compound is a viscoelastic damping compound that converts sound energy into a minute amount of heat. Very simply, when used between two rigid layers of material, typically drywall, the compound works to isolate the noise traveling from one room to the other.

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

How does green glue work?
Green Glue Noiseproofing Clips work to mechanically decouple one side of the wall from the other, thereby reducing the amount of sound energy travelling through the frame. Mechanically separating two sides of a wall can improve sound isolation by allowing one side to vibrate independently from the other.
How thick is joist tape?
The Joist Tape is sold in widths to fit standard joist sizes: 1-7/16”, 2-1/4”, and 3”, and are 1/8” thick and 100 feet in length ( 3.6, 5.7 and 7.6cm and 30m in length). Joist Tape is only used to address the noise from squeaks when the subfloor rubs onto the joists.

Typically, after the sealant is applied, you will “mud and tape” the final joints as normal. For decoupled walls choose constructions materials designed to finish with slight movement.
How many feet of noiseproofing sealant?
Each tube of our Noiseproofing Sealant, used to prevent sound flanking, typically provides 40-80 linear feet (12-24 m) of coverage, depending on the size of the hole cut in the nozzle.

Just treating the ceiling below can have a huge impact on path 1, and help with path 2, but does nothing for paths 3, 4, or 5. You see, once noise is in a structure, the low damping of common building materials allows it to move wherever it wishes, and sound moving around through a structure has a tendency to find its way to where you don't want it to be.

Sorry to hear that. Soundproofing an existing structure from impact noise is quite difficult and usually not very effective.

Impact noise occurs when an object collides with another object, and you usually hear it from the floor above you. Examples include footsteps, a chair sliding across a wood or tile floor, or an object falling on the floor. Impact noise travels freely through a structure and through air pockets. The diagram below illustrates all the pathways ...

Does green glue reduce noise?
Green Glue Noiseproofing Compound. Applying layers of Green Glue Noiseproofing Compound to the floor above is effective at damping airborne noise, but NOT greatly reduct impact or other structure-borne noise. The compound dissipates the vibrations caused by sound waves as they move through a structure. The compound is applied between two rigid materials (for example, OSB subflooring), and unlike other noiseproofing options, it reduces noise at all frequencies.
