FiberTite® 50 Mil XT Fleece back Membrane

Seaman Corporation’s 50 mil FiberTite-XT-FB “fleece back” membrane features an 18 x 18 / 1,100 x 1,300 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

    50 mil FiberTite-XT-FB “fleece back” is a 42-oz sq. yd/nominal
    50-mil (1.27 mm) thick membrane and is an Xtra-Tough version
    of the FiberTite family of membranes. 50 mil FiberTite-XT-FB not
    only goes well beyond the requirements enumerated in ASTM
    D6754-15 Standard Specification for Ketone Ethylene Ester (KEE)
    Based Sheet Roofing, but surpasses the physical properties and
    performance characteristics of 90-mil competitive products.
    The 50 mil FiberTite-XT-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. 50
    mil FiberTite-XT-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.
    50 mil FiberTite-XT-FB is coated face and back 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. Additionally, 50 mil
    FiberTite-XT-FB exhibits superior tear, puncture, fungus, algae
    and flame resistance that make FiberTite Roofing Systems some
    of the most sustainable roofing systems available.

    Application

    50 mil FiberTite-XT-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.
