Fastening Procedure: It is important to
work from one side of the panel to the other.
Begin fastening from the top of the panel to
the bottom. Moving across the panel, attach
fasteners at the top and bottom of the panel
until you reach the next stud. When using
staples, fasten them in a parallel direction to
the stud. Continue in the same manner until
the Thermo-ply panel is properly secured
to the frame. In order to prevent gaps or
rippling, move across from one side of the
panel to the other when installing. DO NOT
fasten each of the four corners rst.
1-Hour Fire Resistive Construction:
Thermo-ply Structural Grade~Red and
Structural Grade~Blue may be used in a 1-
hour re-rated wall system, in accordance
with the Standard Methods of Fire Tests of
Building Construction and Materials using
ASTM E-119 testing procedures. Refer to
individual code reports for various approved
wall assemblies and limitations.
Perm Rating: Perm ratings range from
0.53 - 0.63 depending on grade.

PRODUCT NAME
Thermo-ply® Sheathing
PRODUCT DESCRIPTION
Grades: Standard Grade (green) .078”
Structural Grade (red) .113”
Structural Grade (blue) .137”
Basic Use: Thermo-ply Sheathing is used,
where required by code, to provide support
for interior and exterior wall surfaces for the
lifetime of the structure. Installing sheathing
on an entire home or structure is generally
the most common industry practice. Several
additional uses exist, including corner
bracing.
Precautions and Limitations: Refer to
individual code reports for the various ndings
and limitations applicable to the specic code
areas of inuence.
Composition and Materials: Thermo-ply
Sheathing is composed of high-quality, long-
bered, specially treated water and weather-
resistant plies. Plies are pressure laminated.
A special water-resistant adhesive is used.
Standard sizes are 48” x 96”, 48.75” x 96”, 48”
x 108” and 48.75” x 108”. Custom cut sizes
up to 60” wide and 144” long are available
upon request. Thermo-ply is available with
a variety of approved outer facings, including
poly and foil.
