Installation Instructions
• wood laminate
• carpet and padding
1. Install Floor Mat
• Roll out QuietZone Acoustic
Floor Mat directly on top of the
subfloor so that the entire floor
surface area is covered and
3-4” of floor mat is turned up
along wall.
• Butt adjoining edges of floor
mat against each other and
tape all seams with standard
(2” wide) building tape. Also,
tape the turned up edges to
the wall to help with installation
of the wood raft.
• Ensure the QuietZone Acoustic
Floor Mat is free of any tears or
punctures.
2. Install Plywood Raft on Top
of Floor Mat
• Combine two layers of 3 ∕8” (or
thicker), exterior, AC-grade
plywood together. (Note: two
layers of ½” plywood should be
used with hardwood finished
flooring.) Select plywood that
is uniform, flat, dry and free
of defect to ensure that the
finished floor is level. Allow the
plywood to become acclimated
to the environment so that the
wood is dry and the moisture
content has stabilized. This can
be done by standing the panels
on edge for several days in
the rooms where they will be
• Place one layer of plywood
directly on top of the floor
mat so the entire surface area
is covered. Space the plywood
panels so that there is a 1 ∕8”
gap between adjacent pieces of
plywood and from the walls.
• Apply an even coat of standard
wood glue to the top surface
of bottom layer of plywood,
and then place a second
layer of plywood onto glued
surface. The second layer of
plywood should be oriented
perpendicular to the bottom
layer with the joints staggered.
The finished surface of the
plywood forms the top surface
of the raft. Space the plywood
panels so that there is a 1 ∕8”
gap between adjacent pieces of
plywood and from wall.
• Fasten the two layers of
plywood together using ¾”
long wood screws spaced 12”
apart across entire surface
area, including the joints and
perimeter. Use 1” long screws
when ½” plywood is being
installed.
NOTE: Since wood is a natural
material, it is susceptible to
dimensional change. Providing
a gap around all edges of
the plywood panels should
accommodate any dimensional
change. However, in the
event that the plywood raft
does not lay evenly over the
QuietZone Acoustic Floor Mat,
one may selectively screw
down the plywood raft (up to
16” oc) without significantly
compromising the acoustic
performance of the system. Care
should be taken to use wood
screws that completely penetrate
the subfloor without entering into
the floor joists.

3. Install Finished Flooring
• Install the finished flooring
as recommended by the
manufacturer.
• Ensure that the finished
flooring is installed close
enough to the wall so that the
finishing trim will conceal the
QuietZone Acoustic Floor Mat.
NOTE: Floor mat strip should
form a sealed, right angle with the
floor mat on the subfloor.
