FiberTite® 45 Mil SM Fleece back Membrane

Seaman Corporation’s 45 mil FiberTite-SM-FB “fleece back” features an 18 x 19 / 840 x 1,000 denier weft reinforced

polyester knit fabric, coated with a proprietary compound, utilizing DuPont’s™ Elvaloy® Ketone Ethylene Ester (KEE)

as the principle polymer in the hybrid vinyl alloy coating.

Specification
  • 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.
