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.

please consult the most current versions of Seaman Corporation’s
Guide Specifications for the Installation of FiberTite Roofing
Systems.
