Description
45 mil FiberTite-SM-FB “fleece back” is a 40-oz sq. yd/nominal
45-mil (1.1 mm) thick membrane. 45 mil FiberTite-SM-FB not only
meets or exceeds the minimum physical property requirements
enumerated in ASTM D6754-15 Standard Specification for
Ketone Ethylene Ester (KEE) Based Sheet Roofing, but exceeds
the physical properties and performance characteristics of 60-mil
competitive products.
The 45 mil FiberTite-SM-FB membrane incorporates a 4-oz per
sq. yd non-woven polyester felt, heat bonded to the back side of
the membrane with a 3-in selvedge edge for field welding. 45 mil
FiberTite-SM-FB fleece back is manufactured in conventional 72-
in by 80-ft roll goods.
Seaman Corporation is vertically integrated, which allows complete
control over the manufacturing process from the selection of the
yarns, to the engineering, knitting and weaving of the base fabrics
to the final coating process. Today, FiberTite Roofing Membranes
are the result of Seaman Corporation’s 60 years of applied fabric
engineering and coating technology.
All FiberTite Roofing Membranes are constructed using high
tenacity/heavy weight yarns to create a base fabric reinforcement
to impart superior puncture, tensile and tear resistance properties.
The base polyester fabrics are primed with a unique and
proprietary adhesive coat that lays the foundation to physically
bond the KEE coatings to the “fiber” to maximize seam strength
and overall membrane performance.
45 mil FiberTite-SM-FB is coated on the face with Seaman
Corporation’s original “KEE” formulation to provide superior
hot air welding characteristics, extreme UV resistance, broad
chemical resistance and long-term flexibility and reparability for
the installed roofing membrane system. The back side of the
membrane is coated with a slightly modified (SM) economical
version of Seaman Corporation’s original KEE compound to control
membrane costs while offering additional thickness and weather
ability. Additionally, 45 mil FiberTite-SM-FB exhibits excellent tear,
puncture, fungus, algae and flame resistance that make FiberTite
Roofing Systems some of the most sustainable roofing systems
available.
Application
45 mil FiberTite-SM-FB Roofing Systems are installed by adhering
the “fleece back” membrane in FTR-290 low VOC solvent borne
adhesive, FTR-390 water borne asphalt emulsion, FTR-490 water
borne elastomeric adhesive, FTR CR-20, or hot asphalt to a variety
of pre-approved substrates.
For specific installation recommendations and requirements,
please consult the most current versions of Seaman
Corporation’s Guide Specifications for the Installation of FiberTite
Roofing Systems.
