Since 1979, there has never been a membrane failure with a FiberTite® Roofing System. Even after exposure to rooftop elements for many years, FiberTite continues to out-perform competitive products. In frigid temperatures, prolonged UV exposure, high wind uplift, chemical and fatty acid buildup, FiberTite remains flexible and strong. It continues to resist puncture and tears. And it continues to reinforce its reputation as the world's finest roofing membrane.
