Green Glue Noiseproofing Compound Case of 12
Green Glue Noiseproofing Compound is a viscoelastic damping compound applied between two layers of drywall. It converts the mechanical energy of sound into a very small amount of heat, which stops the panel resonating and passing sound through.
Green Glue: Case / 12 tubes
Adding a second layer of drywall adds mass, and mass helps. But two sheets screwed tightly together behave like one thicker, stiffer sheet and still resonate. A damping layer between them lets the sheets shear against each other very slightly, and that shearing is where the sound energy is lost.
How it is applied
The compound is applied in a random pattern from the tube onto the back of the second sheet, which is then fixed within the manufacturer's stated open time. It is not a glue and it is not meant to bond the sheets rigidly.
Coverage
At the recommended rate the case covers roughly 192 square feet, which is about six sheets of 4 by 8 drywall using two tubes per sheet.
Specifications
| Supply | Case of 12 tubes |
|---|---|
| Tube size | 28 oz |
| Coverage per tube | Approximately 16 square feet at recommended rate |
| Recommended rate | 2 tubes per 4 by 8 sheet |
| Low frequency option | 3 tubes per sheet |
| Case coverage | Approximately 192 square feet |
Worth knowing. More is not better. Performance improves up to about three tubes per sheet and then declines, so applying extra compound wastes material without improving the result.
