HOW TO DEADEN SOUND THROUGH
Floors Walls Ceilings
Easy Cut and Glue
Maintain 3/16 Spacing Between Panels
Read All Instructions Carefully
Nail and Finish Floors and Walls Packaging, Storage and Protection
All Homasote products having a maximum 4 width are packaged in plastic covered units. However, when
stored outside, all materials should be stored above grade on wooden pallets and covered by waterproof
tarpaulins. Packaging material is not intended for exterior job site protection.
Interior Applications
General Requirements:
Temperature and humidity conditions closely approximating those which will exist when
building is occupied shall be maintained before, during, and after the application of panels. Installation shall not be
made when building is excessively dry, cold, hot or damp.
All panels shall be removed from plastic covered units
and separated not less than 24 hours prior to installation to allow material to acclimate.
Applications as a Floor Underlayment
During installation, leave a 3/16" space between each panel. All panels must be spaced 3/8" from all walls and
partitions at all times. This will allow for the natural expansion and contraction of the Homasote panels. On runs
over 50, provide 1/2" expansion joint. All panel joints must be staggered regardless of panel size. When installing,
hold annular threaded nails or screws back a minimum of 3/4" from all panel edges.
Applications as a Wall Panel
Homasote panels should be applied vertically to the framing with blocking or plates at top and bottom of panel.
All edges of panel must fall on framing at all times. If an edge does not fall on any framing, then blocking
must be installed. Framing for 1/2" thick panels must not exceed 16" o.c. Framing for 5/8" and 3/4" thick
panels must not exceed 24" o.c. During installation, all panels must be installed vertically leaving 1/8"
expansion gap between sheets and 1/4" expansion gap at floor, ceiling, and around window and door frames,
etc. Do not fill or tape panel joints. Vertical installation only. If left exposed 440 SoundBarrier may be painted
with a quality latex based primer and finish paint applied by brush and/or roller. DO NOT SPRAY PANELS.
4) Follow immediately with nailing or screwing of Homasote panel to
wood sub-floor; from the center out, using annular threaded nails or
screws of sufficient length to penetrate a minimum of 1/2" into wood
sub-floor. Nail or screw as shown in the "Glue-Nail/Screw Pattern Over
Wood Sub-floor" below. Nail or screw Homasote panel additionally in
any areas that are not lying down flat into adhesive.
Note: If adhesive is omitted, panels must be nailed or screwed 6" o.c.
along panel edges and 10" o.c. throughout the field of the board.
5) Follow with next panel, leaving 3/16" expansion space between panels
and 3/8" off walls and partitions at all times.
6) After a minimum of 48 hours for adhesive to set, nail tackless strips to
the top of wood nailers, followed by the installation of carpet and pad.
Over Wood Sub-Floor
Wood sub-floor must be flat (not cupped), dry lumber, level and
securely fastened to joists. Shim or sand sub-floor as necessary
to provide flat surface continuity for Homasote panels.
Note: Performance Specifications AFG-01 (developed by APA
The Engineered Wood Association) requires that glues applied
at the job site be sunlight resistant, strong under many
moisture and temperature conditions, and able to fill gaps.

Carpet and Pad Method 1
Homasote AND Tack strip installed directly to wood sub-floor.
1) 1/2" thick by 1-1/2" wide wood nailers shall first be nailed and/or glued
to wood sub-floor at all locations where tackless strips are to be used.
Note: 1/2" tack-strip shims are available and may replace wood nailers
around perimeter of room for attachment of carpet and pad. Contact
your local flooring dealer for more details.
2) Apply a 3/8" bead of APA-approved sub-floor adhesive meeting APA
AFG-01 specification to Homasote panel, holding back 3/4" from panel
edge, as shown in the "Glue-Nail/Screw Pattern Over Wood Sub-floor"
below.
3) Turn Homasote panel over and place adhesive side down to wood
sub-floor.
