Description
The FlameSafe®Intumescent
Wrap Strip (FSWS) is a highly
flexible, resilient strip designed to
firestop combustible penetrants in
fire-rated walls and floors.
Highly intumescent, the FSWS
rapidly expands to form a dense
char to prevent the spread of fire,

smoke and toxic gasses when
exposed to temperatures in excess
of 250°F (121°C). The FSWS
continues to expand up to 1000°F
(538°C). Available in 12 ft
(3.65 m) rolls, the FSWS is easy
to cut and fabricate to match the
circumference of the penetrant.

Application
The FlameSafe Intumescent Wrap
Strip is used in conjunction with
sealant as a “tuck-in” system or a
restraining collar to firestop
combustible penetrants such as
PVC, cc-PVC, CPVC, FRPP,
cc-ABS and ABS pipe, as well as
insulated pipe. It has been tested
and approved for use in concrete
floor/wall, gypsum wall, as well
as wood joist and wood chase
wall floor/ceiling assemblies.
Applications where annular space
is restricted may require the use
of the FlameSafe Restraining
Collar with the wrap strip.

Installation
Installation temperature should
be between 40°F to 90°F (4°C to
32°C). Wrap a layer of the
FSWS, cut to size around the
penetrant and hold in place with
masking tape.
Refer to the appropriate UL
approved system for specific
application requirements. Once
the wrap strip is in place, the
system may require caulk, such as
FlameSafe FS 1900 Sealant, to
ensure a tight smoke seal. The
FSWS is available in two sizes:
If system requires multiple wrap
12 ft x 1 in. x 0.25 in. (3.65 m x
strips, overlay layers of wrap
25.4 mm x 6 mm) and 12 ft x
