FiberTite® XT - Waterproofing Membrane

FiberTite® XT features a reinforced polyester knit fabric, coated with a proprietary compound, utilizing ELVALOY™ Ketone Ethylene Ester (KEE) as the principle polymer in the hybrid vinyl alloy coating.

The membrane is a nominal 1.27 mm thick and is an Xtra-Tough version of the FiberTite family of membranes. It not only exceeds the minimum physical property requirements in EN 13956 but was used as the benchmark for the development of ASTM D6754-15 Standard Specification for Ketone Ethylene Ester (KEE) Based Sheet Roofing. It exceeds the physical properties and performance characteristics of many other thicker membranes.

Carefully manufactured to allow strict control over the production 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 over 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 provide 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 'fibre' to maximize seam strength and overall membrane performance.

The membrane is coated on the face and back with an 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. It exhibits superior tear, puncture, fungus, algae and flame resistance that make FiberTite Roofing Systems some of the most sustainable roofing systems available.

The membrane is manufactured in 2.54 m wide x 30.48 m long rolls. Laps in the membrane sheets are joined by fusing the thermoplastic membrane with appropriate hot air welding equipment, set at the correct welding temperature. CE marked.
