Often after buildings are occupied, noise problems are discovered. At this point it may be too costly and disruptive to remove drywall and add our high STC IsoMax clips. Sound Damp2 allows the easy addition of a layer of drywall, and raises the STC of the wall much higher than drywall alone. Whether used as a retrofit or to meet building code for new construction, Sound Damp2 is the “go to” building material.
- Sound Damp2 can save valuable installation time with its more efficient application method.
- Damping compounds are traditionally applied with caulking guns. Manufacturer instructions include specific patterns and quantities to achieve maximum performance.
- Sound Damp2 replaces tubes and caulking guns with an inexpensive and disposable low-nap roller. Sound Damp2 is applied continuously across the entire back of the drywall sheet, reducing application time and eliminating the guesswork of proper consistency.

STC Ratings and Audibility*
|Sound Source||STC 40||STC 50**||STC 60|
|Loud Speech||Heard||Barely Audible||Inaudible|
|Music||Heard Easily||Heard||Bass notes heard faintly|
*Note: The noise source sound level and the ambient (background) sound level will change what is actually heard in conjunction with the STC rating of the wall
**STC 50 is required by IBC Building Code between units in multi-family buildings
A secondary benefit of damped drywall, when used in critical listening spaces, is reduced room reverberation times and improved low frequency absorption. The room simply sounds better, more articulate. This room acoustics improvement is often desirable in music performance, recording, and home theater spaces.
