10 Ways Membrane Roofing Makes for the Best Roofs @FiberTite
FiberTite roofs outlast the rest because of their unique roofing membrane formula. In fact, the formula hasn’t changed since the start of the company in 1979—why fix something that isn’t broken? The FiberTite roofing membrane utilizes Elvaloy® Ketone Ethylene Ester (KEE). In 1973, DuPont™ developed KEE with the hope of making better roofing materials. DuPont wanted to create a solid plasticizer with a high molecular weight that would not separate from a single-ply polyvinyl chloride (PVC) roof. “Before Elvaloy KEE was created, PVC roofs typically used liquid plasticizers. But liquid plasticizers migrate out of the system. This means the PVC would revert to being brittle and more prone to cracking or shattering,” Ahrens says. Ahrens explains that a solid plasticizer, unlike liquid, bonds with PVC to create a new permanent compound, increasing the longevity and durability of...
