If
an installation requires Acoustiblok to be installed on top of the
subfloor there are different options depending upon the final finish
of the floor.
Carpet
Floor Finish
Unroll
Acoustipad perpendicular to the planned direction of Acoustiblok.
Tape all seams using Acoustigrip tape. If needed run a bead of
adhesive along the edges to prevent the Acoustipad from curling up..
Install
the Acoustiblok and tape all seams using the Acoustigrip tape in one
of the following methods:
Install
the tack strip using fasteners long enough to compensate for the
additional 1/2” height of the Acoustiblok and Acoustipad
underlayments.
Install
the Acoustipad approximately 1 1/2” - 2” away from the perimeter
edge allowing the Acoustiblok to drape over its side, then install
the tack strip on top of the Acoustiblok only.
Install
1’’x 2” furring strips 1/8”-3/8” away from perimeter
surfaces and nail the tack strip on top of it. Use Acoustiblok
Acoustical Sound Sealant to fill in the perimeter gap. The height of
all your materials: Acoustipad, Acoustiblok and the carpet padding,
should be close to even with the top edge of the furring strip.
Install
the carpet padding and carpet per manufacturers’ instructions.
Wood
Floor Finish
Place
the Acoustiwool-WFO.125 Perpendicular to then planned direction of
the Acoustiblok. Allow the Acoustiwool-WFO.125 to float on the
subfloor - do not use any adhesive. Spot glueing may be needed to
prevent the wool from curling up. Do not overlap the material. Tape
all seams.
Next
roll the Acoustiblok over the Acoustiwool - WFO.125 taping the seams
and caulking around the perimeter. You may sot glue the Acoustiblok
onto the Acoustiwool-WFO.125. If the Acoustiblok is not lying flat,
allow it to sit overnight at ambient room temperature.
For
glued down, engineered or solid wood follow the manufacturer’s
installation instructions. Verify compatability of recommended
adhesive with the Acoustiblok material. You may also further decouple
the floor assembly by adding free floating plywood or other suitable
substrate on top of the Acoustiblok as the subfloor. Do not use any
adhesivesin this step; allow the substrate to float freely on top of
the Acoustiblok and Acoustiwool-WFO.125 combination.
For
mechanically fastened engineered or solid wood flooring, you may
install it directly on top of the Acoustiblok following its
manufacturers’ instructions. The recommended installation is to
have a floating plywood substrate as in the previous step. Not only
will this decouple the floor assembly, but also keeps the fasteners
from penetrating to the subfloor below preventing the transmission of
mechanical noise into the ceiling assembly below.
Leave
a 1/8”- 3/8” perimeter gap between the Acoustiwool-WFO.125
Acoustiblok, substrate and flooring from all adjacent wall surfaces.
Fill perimeter gap with Acoustiblok Acoustical Sound Sealant.
Tile
Floor Finish
Subfloor
construction must comply with relevant industry standards.
Place
the Acoustiwool- TFO.11 perpendicular to the planned direction of the
Acoustiblok Sound Isolatiin Material. Use thin set to adhere the
Acoustiwool-TFO.11. Roll flat with a 75lb roller. Do not overlap the
material. tape all seams using Accoustigrip tape.
For
better acoustical isolation you may choose to install the
Acoustiwool-TFO.11 and the Acoustiblok without adhesives and install
free floating plywood or other suitable surface underlayment on top
of the Acoustiblok as the floor substrate. If natural stone tils are
to be installed, a suitable substrate must be installed on top of the
Acoustiblok and Acoustiwool-TFO.11. If only the Acoustiblok is
installed you may install the tiling directly adding Laticrete 333
Thinset Admix or other acrylic bonding agent to your thinset.
Leave
a 1/8- 3/8” perimeter gap between the Acoustiwool-TFO.11,
Acoustiblok and tile flooring from all adjacent surfaces. Fill this
gap with Acoustiblok Acoustical Sound Sealant.
