FiberTite, XT-FB 50 mil Waterproofing Membranes

Sold by AFAB Roofing Ltd.


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 D6754-02 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.

ll 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.
