Acoustical Shielding
A Mass Loaded Vinyl used in Wall Applications

SOUND-ABATE is a mass loaded, limp vinyl sound damping material designed for commercial, industrial, and residential applications to reduce sound transmission.

SOUND-ABATE is designed for installation behind gypsum drywall, finished surfaces to block and dampen sound transmission through the entire sound frequency spectrum.

Place SOUND-ABATE sheet in position at top of the wall. Align vertical edges over center of studs. Insert staples along top edge of sheet to hold in place. Allow SOUND-ABATE to unroll vertically along the height of the wall. Apply additional staples along vertical edge if desired. For each additional sheet of SOUND-ABATE to be installed, repeat the previous procedure. Note: Ensure vertical seems center over studs. Trim sheet if necessary. Locate any wall outlet penetrations that will require access and cut an X access point for each. Caulk floor, ceiling, and corner joints before installing drywall.
