Material checklist:
RD350
Acoustiblok roll dispenser (ball bearing rollers allow for easy roll
out and height adjustment of up to 2000 lb rolls). Recommended for
use with Acoustiblok 60' and 350’ Master size rolls.
Screw

*
Acoustigrip™
tape # AGT60 (180'/roll) and dispenser. Requires approximately 1 roll
per 60 linear feet of Acoustiblok.
*
Acoustiblok Acoustical Sound Sealant # AC10 (10oz tube). Installation
requires approximately 2 tubes per 60 linear feet of Acoustiblok.
Also available in 29oz tube and 20oz sausage tube sizes.
*
Acoustiputty™
acoustical sealant pads. Use 1 pad to seal the back of each
electrical box or other wall penetrations.
Self-tapping
wafer head screws # WHS (1000/box) if using metal studs.
Approximately 1 box per 150 linear feet of Acoustiblok. If using
timber stud, the requirement is staples (min. 1/2")
approximately 200 per 60 linear feet of Acoustiblok. Tin caps # TC5
(1000 tin caps per box). Multiply 0.78 x square footage for total
amount needed, or 1 box is enough for 4 - 60' rolls.
Installation
Method Suggestions:
If
only one layer of Acoustiblok is used, install it on the side where
the sound originates.
Use
a minimum of 12.5mm or 15mm thick drywall.
Space
all power outlets so that they are not back to back (should be in
different stud cavity to help isolate sound). Attach Acoustiputty
pads to the back of the electrical boxes or other voids for a tight
seal to further insulate
the
noise.
If
in-wall speakers are used you must leave Acoustiblok loose enough in
the wall cavity to provide enough clearance for the speaker back. The
goal is to achieve an "airtight
seal"
over the structure.
Standard
timber or metal studding should be applied to the existing masonry
wall. Ideally the studs should be de-coupled via the ceiling track
and floor plates; if coupled, studs are used they should be gasketted
to prevent passage of sound through the wall.
Install
Acoustiblok running horizontal, not vertical if possible. This will
minimize the number of seams requiring sealing. If using vertical
drops of material ensure overlaps are made over cavities to eliminate
bulging over studs and bowing in the drywall finish.
Precut
Acoustiblok. Measure total length (per wall) and identify section
location. Cut full lengths when possible to minimize vertical seams.
Any vertical seams must be centered on a stud. Always add 6" to
12" to length to insure full length coverage.
Install
bottom run first, and then work up. Overlapping the seams is easiest;
however, this may cause a slight bow in the drywall. This however can
be greatly reduced by using resilient channels (horizontal bars)
before applying a drywall. If you overlap the seams, overlap by a
minimum of 25mm, and apply Acoustiblok Acoustical Sound Sealant in
the overlap area. Do not put any fasteners into the overlap area.
Butting the seams is the recommended method; however, this method
requires a patient and detailed installation. The 32oz Acoustiblok
can not be overlapped due to its thickness.
Insure
joints are clean and dry (use denatured alcohol if needed) before
applying Acoustigrip or Acoustiblok Acoustical Sound Sealant.
Acoustigrip
tape and Acoustiblok Acoustical Sound Sealant must be used to
properly seal all seams regardless of installation method.
Use
self-tapping wafer head screws # WHS (4-5 screws per stud).
Cut
around all receptacles and other wall penetrations.
Caulk
all possible air gaps (especially floor and ceiling joints) with
Acoustiblok Acoustical Sound Sealant.
Tape
all joints & edges with Acoustigrip tape.
An airtight
assembly is the goal.
Insure
proper fiberglass insulation is put in wall 3½” to 4” of loose
fiberglass should be used in stud cavities. Paper side away from
Acoustiblok.

Notes:
Acoustiblok
is a very unique material. Duct tape, aluminum tape, regular silicone
& most caulks will adhere initially, but may lose the bond in a
few days, jeopardizing the performance of your installation. Use
Acoustiblok’s installation products to insure an airtight, long
lasting, professional sound reduction installation.
Installing
Acoustiblok on the interior side of an exterior wall requires
attention to the vapor flow performance of the wall assembly. To
provide adequate vapor flow the material seams should be overlapped.
Use the Acoustiblok Acoustical Sound Sealant and spot apply it to the
center of each wall cavity. Do not tape the seam or apply acoustical
sealant along the bottom of the assembly. Do not put any fasteners
within the overlapped area.
Install
the channel 24"o.c. perpendicular to the studs over the
Acoustiblok material and then screw the drywall to the channel. Do not
penetrate the Acoustiblok material with the drywall screws. Use
screws that are long enough to penetrate the drywall and channel
only. Install the drywall so that it does not
touch the floor, ceiling, or adjoining walls providing mechanical
decoupling (1/8"-3/8” gap) of the wall.
Always
install the Acoustiblok Sound Isolation Material with the logo and
U.L. printing visible. This allows for quick inspection and sign off
from building inspectors and assurance to your clients that they have
received an actual Acoustiblok sound reduction treatment, not an
inferior, non U.L. rated and acoustically untested product
substitution.
