The FiberTite-SM not only meets or exceed the minimum physical property requirements for Ketone Ethylene Ester (KEE) Based Sheet Roofing, but exceeds the physical properties and performance characteristics of competitive products. 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. FiberTite-SM Roll 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. These 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. Additionally, These roll exhibits excellent tear, fungus, puncture, algae and flame resistance that make FiberTite Roofing Systems some of the most sustainable roofing systems available. FiberTite-SM Roll is also available in customized prefabricated roll widths and lengths that incorporate integrated fastening tabs, sealing tabs. Field seaming of the membrane is accomplished by fusing the thermoplastic membrane with conventional hot air welding equipment.
