FiberTite provides operational security globally to the world’s most powerful brands with an innovative, high performance coated fabric membrane that has a unique, four-layer technology providing puncture, chemical, and ponding water resistance.

FiberTite’s history of proven longevity and performance cannot be matched because the correct amount of KEE can only be determined by real-world weathering and endurance. FiberTite is the only roofing membrane that exceeds ASTM D-6754, a standard designed specifically to define which products are truly KEE membranes and which are not.

As the only manufacturer that meets the criteria, we can assure customers that FiberTite roofing systems will result in increased building performance through energy efficiencies, durability, stability, and overall life cycle cost. FiberTite been using the same formula for 40-plus years and have roofs still in service after more than 35 years.
