Sound Isolation - Soundcor Green
Sound waves in your theater come in all shapes and sizes. Higher frequencies such as those coming from surround and front speakers are often treatable with acoustic panels that are absorptive. Lower frequencies such as bass from the subwoofer are much wider and far reaching in their wave structure. Low voices, the sound of thunder or rain, a train approaching its stop, or the pounding of a battlefield are all within this category. A heavier and more compressed material, along with specific construction is required to stop transmission of these sounds through walls.
SoundCor Green is a sound barrier material that is placed behind a finished drywall surface during new construction or a renovation. Composed of a flexible vinyl only 1/8" thick, it arrives to the job site in rolls of 4' x 25' ready to be installed. Its dense composition creates a barrier within the theater shell, and reduces the amount of sound that escape to other areas of the home. Depending upon the wall construction and materials used around Soundcor Green, the effectiveness to block sounds will vary.
Eco Frendly
SoundCor Green is produced from post recycled automotive products, reclaimed from the landfills providing a second life to the material.
Professional Grade
Don't mistake this product for "do it yourself" solutions. Soundcor Green is a professional grade product, impeding much lower frequencies then those available to the public through the internet or builders warehouses. In addition, DIY installation manuals are often misguided, omitting exact details that are critical to effectiveness of the product. Once the drywall is up, it's often too late to make any corrections.
How much improvement will I see?
Most homes are built with wood stud walls, 16" on center with insulation between, achieving a STC-33 rating. Adding SoundCor Green to one side of your wall yields an STC 41 to 45 rating, providing a dramatic improvement in sound blockage. Although not required and not often possible, covering both stud surfaces can produce 75% or more sound reduction.

Soundcor Spec Sheet
Stud Walls
Soundcor Green can be nailed to the stud walls directly, with a 5/8" layer of plywood placed over it so that the final layer of 5/8" drywall can easily be installed to a flat surface. In some cases, a layer of plywood can be placed between the stud wall and Soundcor Green to make installation of the Soundcor Green easier. A consultation with the general contractor will best determine their preference. Adding an additional layer of plywood increases the effectiveness of the product.
Stud Walls and Plywood Layer
There is no need to remove the plywood layer, Soundcor Green can nail directly over it and then the final layer of 5/8" drywall can be placed on top. As Soundcor Green is flexible, some choose to place yet another layer of 5/8” plywood over it before assembling the drywall to ensure a flat base. A consultation with the general contractor will best determine their preference. Adding an additional layer of plywood increases the effectiveness of the product.
Finished Drywall
If the room is large and another ¾" to 1-3/8" of depth is acceptable per surface, Soundcor Green can simply be mounted on top of the drywall, with another layer of drywall going on top. As Soundcor Green is flexible, some choose to place yet another layer of 5/8" plywood over it before assembling the drywall to ensure a flat base. A consultation with the general contractor will best determine their preference. Adding an additional layer of plywood increases the effectiveness of the product.
In the event that space is limited, drywall can be removed to stud level, see Stud Walls explanation for details.
