Products / 36 mil FiberTite Membrane

36 mil FiberTite, introduced by Seaman Corporation in 1979, is a KEE (Ketone Ethylene Ester) single-ply roofing membrane built on an 18x19/840x1,000 denier weft-reinforced polyester knit fabric coated face and back with Seaman's original KEE formulation. It was the benchmark membrane used to develop ASTM D6754. The manufacturer's own site describes KEE membranes as an "advanced type of PVC roofing."
