FiberTite: Intelligent Roofing Solutions

Craftsmanship that Lasts Decades

FiberTite technology delivers tough, long-term protection

The foundation of FiberTite is 60 years of high-performance fabric technology. 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, no FiberTite roof has ever suffered a membrane failure. That's why we've never had to change our formulation.

Fabric Layer

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.

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.

FiberTite Roofing MembraneFace 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.

FiberTite's Special Formula

Can you afford to trust your roof to a knock-off?

FiberTite is manufactured with the proven amount of Elvaloy® Ketone Ethylene Ester (KEE)

FiberTite sets the performance standard in roofing through the proven use of Elvaloy KEE. Our proprietary coating formula is the American Society for Testing and Materials (ASTM) standard for the use of KEE and forms a monolithic bond with our outstanding fabric. More than 30 years of performance demonstrates that FiberTite roofs simply do not fail. When the weather turns ugly, you can put your trust in the very best single-ply roofing system available.

The only true measure of a roofing membrane's performance is time.

After 25 years of rooftop exposure, a 36-mil FiberTite roofing membrane retains:

  • 80% of its original physical properties
  • 60% of its original thickness over the fiber

What is KEE?

DuPont™ Elvaloy® Ketone Ethylene Ester (KEE) is a solid, flexible, high-molecular ingredient ideal for thermoplastic processing. Its careful use in the production of FiberTite roofing helps FiberTite remain stronger and more flexible with age.

What is the correct amount of KEE?

The correct amount of KEE can only be determined by the track history of the product. The original FiberTite KEE sheet was adopted as the industry standard by the ASTM. FiberTite is the only known single-ply KEE sheet on the market that meets the ASTM standard D6754. FiberTite is the only KEE-based membrane on the market proven for nearly four decades – exceeding roofing industry professionals' expectations.

How FiberTite uses KEE better

The monolithic structure of a tighter, lighter woven fabric and the correct use of KEE in FiberTite enables it to:

  • Remain flexible for decades
  • Repel harsh chemicals
  • Prevent delamination over time
  • Resist tears and punctures
  • Withstand severe weather
  • Accommodate efficient installation techniques
