FiberTite® FB - Waterproofing Membrane

FiberTite® FB 'fleece-back' 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.

It is a nominal 0.9 mm thick membrane which not only meets or exceeds the minimum physical property requirements in EN 13956 and ASTM D6754-15 Standard Specification for Ketone Ethylene Ester (KEE) Based Sheet Roofing, it also meets or exceeds the physical properties and performance characteristics of many other thicker membranes.

The membrane incorporates a 135 g/m² non-woven polyester felt, heat bonded to the underside of the membrane with a 75 mm selvedge edge for field welding. It is manufactured in conventional 1.83 x 24.38 m rolls.

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.

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 excellent tear, puncture, fungus, algae and flame resistance.

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.
