leaves ample room for growth and opportunity. These statistics show that
spray foam contractors can grow their
business by adding firestop material installations to their service offerings.
“In terms of jobsite management, general contractors are more inclined to go
with the bid of a spray foam contractor
that can also perform firestop installations,” said International Fireproof
Technology, Inc’s (IFTI) Gary Wolfe.
“I believe spray foam contractors can
capitalize on this because they already
possess great knowledge about the installation of fire-protective coatings, so
if they can take the next step and implement firestop materials to their services,
they can increase their profitability.”
Firestop systems come in an array of
products for each strategic application.
Companies like IFTI offer patented
firestop products that have undergone
a series of testing to ensure quality,
performance, and code compliance.
Product testing includes compliance
with Underwriters Laboratory (UL)
inspections with respective UL 1479
(T-rating and F-rating), as well as ULC
S-115 and ASTM E662 testing. Furthermore, IFTI’s Firestop product line
provides cutting-edge firestop technology for each type of application.
JOINTS, DOORS, AND WINDOW
Openings around the joints of fire-rated structures that are not protected by
firestop systems can easily provoke the
passage of smoke and fire between assemblies. The same can be said of the
voids around doors and window frames.
To maintain the integrity of fire separation in these problem areas, filling
these seams, gaps, or voids with a caulking fire barrier sealant such as IFTI’s
sealant products Silicone Fire Barrier (INNS2460) and the water-based
acrylic Fire Barrier Caulk (INSS1440)
can provide effective protection.

“Fire barrier sealants are especially important because they can be used in
conjunction with other firestop products,” said IFTI’s Brad Glazier. “These
products are ready to use when needed
in virtually all types of penetrations.”
DUCTS AND ELECTRICAL CONDUITS
When air ducts and electrical conduits
are pushed through a wall or floor assembly, they create a penetration, which
can allow flames, noxious gas, or smoke
to pass through. In order to plug these
gaps, applicators often use Firestop
putty, which is flexible material with
fast-reacting intumescent properties.
Depending on the size of the gap, the
applicator refers to Listed Designs and
determines how much putty to use. IFTI’s firestop putty products (FM011
and FM012) effectively expand and
plug the gaps found on air ducts and
electrical conduits on fire-rated walls
“An important function that putty
serves is that it expands to block out any
sort of smoke or heat transfer and contains it,” said Glazier. “It is easy to apply
and can be reused, or ‘re-penetrated,’ if
PLASTIC OR INSULATED METALLIC
The spreading of fire can also occur
through pipe openings. If plastic or
metallic pipes are exposed to smoke or
flames, there needs to be a firestop system in place that prevents the passage of
these combustible agents.
In this particular case, IF TI’s INFS0812
intumescent strips can be used to tightly
seal the openings left by burned plastic
or insulation around metallic pipes and
contains the passage of smoke or fire.
IFTI’s fire-resistive elastomeric strips
are bonded on one side to aluminum
foil and they are used in conjunction
with IFTI’s SCCI Cramping Collars,
which is then wrapped around the plastic or metallic pipe and results in restoration of fire resistance rating of walls.
