Our Sound-Engineered Plywood (SEP) product contains no metal
and has tapered tongue-and-groove construction. This plywood is for
new construction or easily fits over your existing subfloor to deliver
superb acoustic performance. Use it to solve noise problems with hard-surface
floor coverings such as hardwood, marble, stone, or vinyl tile. STC
rated to 61 and IIC to 51, and available with anti-mold protection.
Use Supress Sound-Engineered Sealant on any cut-outs or penetrations.
Supress Sound-Engineered Plywood is available in the following 4 x 8 ft width panels, with a square edge:

Sound-Engineered Sealant |
Use on all panel edges, joint or seams. |
Seal Cut-outs and Penetrations
Due to the aggressive nature of air- and structure-borne sound, Supress recommends that any cut-outs or penetrations in the flooring system for mechanical, HVAC, pipes, wiring, fire sprinkler nozzles, etc. be completely sealed with Supress Acoustical Sealant.

Prepare Surface and Materials
The joist and cross-member edges must be reasonably clean and dry.
Remove nails, screws or any obstructions which are covering or protruding
from the joist and cross-member line.
Protect smooth panel faces and tongue and groove edges from damage
prior to and during installation. To minimize the potential for panel
buckling and/or nail-pop, allow Supress SEP panels to equalize their
moisture content at the job site by allowing air circulation on all
sides for a few days after delivery.
Measure and Cut
Measure the space and, if needed, cut the panel (with standard or
carbide-tipped saw blades) to the proper size, minimizing the gaps
between panels and with other surfaces.
Glue and Attach
Glue-nailing is recommended for Supress SEP panels. Use adhesive conforming
to ASTM D3498 and spread only enough adhesive in a 1/4" bead on framing
members to lay 1 or 2 panels at a time. This is particularly important
in warm weather conditions where the adhesive will dry more quickly.
Panels may also be nailed only with appropriately-sized cement-coated
ring- or screw-shank nails. Specifications to be provided by project
structural engineer.
Glued tongue and grooved edges are recommended under thin floor coverings
to keep joints snug. Glue by spreading a thin line of adhesive (1/8"
bead) into the open groove. Avoid using too much adhesive as this
will create squeeze-out and require additional labor for clean-up.
Use 8d cement-coated ring- or screw-shank nails at a maximum spacing
of 6" at supported panel edges and at a maximum spacing of 12" at
intermediate supports.
Attach panels GRADE STAMP UP, away from joist faces and perpendicular
across framing members continuously for at least 2 spans. Stagger
the end joints of the panels across framing members.
Seal Cut-outs and Penetrations
Due to the aggressive nature of air- and structure-borne sound, Supress
recommends that any cut-outs or penetrations in the flooring system
for mechanical, HVAC, pipes, wiring, fire sprinkler nozzles, etc.
be completely sealed with Supress Acoustical Sealant.
