. 2003/ntemationa/ Residentia/ Code@ (IRC)
Properties evaluated:
. Surface-burning characteristics

2.0 USES
Blazeguard@ Fire-Rated Sheathing is used as a roof
sheathing, a wall sheathing, an interior finish, a thermal
barrier, a component of a fire-resistance-rated assembly and
a component of a fire-classified roof covering assembly.
3.0 DESCRIPTION
3.1 General:
Blazeguard@ Fire-Rated Sheathing is a composite panel
consisting of a layer of Pyrotite-an inert, inorganic fire-
shield-factory-applied to either plywood or oriented strand
board (OSB) complying, respectively, with US DOC PS1 or
US DOC PS2. Pyrotite is applied to one or both faces of the
plywood or OSB, either adhesively, mechanically or through
direct application, as described in Section 3.2.
The panels are available in sizes from 4 feet by 8 feet (1219
mm by 2438 mm) up to 8 feet by 24 feet (2438 mm by 7315
mm), and in nominal thicknesses of 3/B inch (9.5 mm), 15/32
inch (12 mm), 1/2 inch (12.7 mm), 5/B inch (15.9 mm) and 3/4
inch (19 mm).
3.2 Methods of Applying Fire Shield:
3.2.1 Adhesive Method: A laminate of the appropriate
thickness (see product descriptions in Section 3.3) is
produced by applying a combination of Pyrotite slurry and
fiberglass mat over a sheet of mylar plastic. The fiberglass
mat shall have a minimum tensile strength in the MD of 30 psi
(206 kPa), and a minimum basis weight of 1.6 pounds per
100 square feet (0.73 kg per 9.29 m2) for 0.045-inch (1.1 mm)
Pyrotite thickness and 1.80 pounds per 100 square feet (0.82
kg per 9.29 m2) for 0.060-inch (1.5 mm) Pyrotite thickness.
The material is rolled with an aluminum fiberglass roller sized
to ensure appropriate thickness and penetration of the
fiberglass. The slurry/fiberglass mixture is then heated and
allowed to cure into a hardened laminate. The laminate, once
cured, is separated from the plastic sheet and trimmed to
size.
The adhesive, Isoset@WD3-A322 crosslinked with CX-47,
manufactured by Ashland Specialty Chemical Company and
recognized in evaluation report NER-165, is roller- or spray-
applied to the surface of a selected substrate material
following the guidelines and instructions of the adhesive
manufacturer. The cured and trimmed Pyrotite laminate is
then placed over the substrate material and placed in a press
for a predetermined temperature and pressure (the
temperature/pressure formula will vary slightly based on the
approved adhesive) until the adhesive is appropriately
hardened.
3.2.2 Mechanically Applied Method: A laminate is
prepared as described in Section 3.2.1. The cured and
trimmed Pyrotite laminate is placed over the substrate
material and attached by mechanically nailing or stapling
through the Pyrotite laminate into the substrate with 3/B-inch
(9.53 mm) staples or nails. Care is taken to ensure the
staples or nails do not protrude through the opposite side of
the substrate. The nails/staples are spaced a maximum of
every 6 inches (152.4 mm) along the perimeter of the panel
and at a maximum of every 12 inches (304.8 mm) over the
entire field of the panel.
3.2.3 Direct Application: The Pyrotite material is applied by
spray application or by applying the Pyrotite slurry through
other means (e.g., roll coating or curtain coating) upon the
surface of an approved substrate. The Pyrotite slurry is
allowed to cure prior to stacking. Excess material is trimmed
from the panel edges. The thickness is determined by
selected substrate and product type (see Section 3.3).
