The FiberTite-XT-FB Fleece Back Roll is an Xtra-Tough version of the FiberTite family of membranes. FiberTite-XT-FB Fleece Back Roll not only goes well beyond the requirements for Ketone Ethylene Ester (KEE) Based Sheet Roofing, but surpasses the physical properties and performance characteristics of competitive products.
The FiberTite-XT-FB Fleece Back Roll membrane incorporates a non-woven polyester felt, heat bonded to the back side of the membrane with a 3 inch selvedge edge for field welding. 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.
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.
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, FiberTite-XT-FB Fleece Back Roll exhibits superior tear, puncture, fungus, algae and flame resistance that make FiberTite Roofing Systems some of the most sustainable roofing systems available
