The 36-mil FiberTite membrane features long-term flexibility and repairability.

Seaman Corporation’s 36 mil FiberTite roofing membrane features an 18 by 19/840 by 1,000 denier weft reinforced polyester knit fabric coated with a proprietary compound, utilizing DuPont’s Elvaloy Ketone Ethylene Ester (KEE) as the principal polymer in the hybrid vinyl alloy coating.

The 36-mil-thick membrane is coated face and back with Seaman Corporation’s original KEE formulation, which provides UV resistance, broad chemical resistance, and long-term flexibility and repairability to the installed roofing membrane system. It also resists tears, punctures, fungus, algae, and flame damage. Specify it in 74-inch- and 100-inch-wide rolls in lengths of 120 feet. Field seaming is accomplished by fusing the thermoplastic membrane with hot air welding equipment.
