FiberTite’s 4-Layer technology synthesizes nearly twice as much fiber as competitors, and features a unique adhesive coat and a proprietary DuPont™ Elvaloy® KEE based formula. It combines to make FiberTite a tougher, lighter, more flexible and durable roofing membrane. First installed on rooftops in 1979, more than 99% of FiberTite roofs are still performing.
Fabric Coat
Base fabric much more important to puncture and tear resistance than thickness. FiberTite’s proprietary knit design incorporates more fiber for unmatched strength and reliability.
Adhesive Coat
FiberTite’s specialized adhesive coating process saturates the individual fibers of the base fabric, creating a molecular bond between the back and face coats of the membrane. This prevents delamination caused by harsh environments. It also keeps moisture from penetrating the cut edges of the membrane and causing seams to fail.
Back Coat
Many manufacturers use a cheap back coat formula that adds thickness and cuts production costs but doesn’t protect well. FiberTite uses the same DuPont Elvaloy KEE based formula in equal weights on the back and face coats for exceptionally secure and lasting welds.
Face Coat
DuPont™ Elvaloy® is the polymeric backbone of FiberTite’s face coat technology. A 30-year proven formula, this layer provides superior UV and chemical resistance, inhibits crazing and cracking, and allows the membrane to remain flexible over the long haul in any rooftop environment. Long-term flexibility makes FiberTite both incredibly long lasting and easier to weld for future rooftop modifications.
