2/2019
•
Keep fasteners as flush as possible, since all protrusions will put a dimple into the
finished wallboard. Fasteners shall not protrude more than 1/16” from Quiet Walls
surface.
• Tightly butt the side of the next sheet of Quiet Walls to the edge of the attached
sheet. Do not overlap seams;
• Tape all seams with Acrylic tape or equivalent. The tape is semi-permanent, and
will be permanently sealed in position when drywall is hung.
o If Quiet Walls is installed horizontally or a seam does not fall on a stud the
seams must be taped preferably with Acrylic tape which provides a long
lasting attachment.
o If seams fall on the stud, with no gaps >1/8”, no taping is required. Drywall
installation will seal the Quiet Walls against the existing studs.
o Commercial Alternatives include commercial duct tape
• Quiet Walls is easily cut to fit around irregular objects and electrical boxes. The
material should be cut around outlets, switches, and junction boxes. Gaps shall be
less 1/8”. If greater, they shall be sealed with acoustical caulk.
• Putty pads should be installed on the back of all electrical boxes;
• Caulk the bottom plate at the floor line with acoustical sealant;
• Install drywall per normal technique (ASTM# C840 – Standard Specification for
Application and Finishing of Gypsum Board). dB-3 will be fastened permanently
when the gypsum board is hung.
