A Superior Process. An Advanced Formula

Fabric With Exceptional Puncture and Tear Resistance. In addition to being the most densely packed polyester fabric available anywhere, we also use the highest strength yarn. Coupled with our proprietary knit design, our membrane delivers exceptional puncture and tear resistance. And, as our membranes get thicker, our fabric gets even stronger.

An Adhesive Coat for Maximum Seam Strength. Next, we apply a unique adhesive coat that encapsulates each yarn, promoting a molecular bond between the base fabric and the front and back coats. This adhesive coat not only inhibits wicking, it also provides maximum peel resistance and seam strength—advantages that cannot be achieved by products that rely on “strike through” adhesion between coats.

Back Coat Provides Superior Welding. The third step in our process is the application of a back coat. The back coat was specifically formulated to provide superior welding properties, effectively maximizing seam strength.

A Face Coat Without Equal for Chemical Resistance and Long-Term Flexibility. The final step in this monolithic membrane is the face coat. Elvaloy and many other ingredients uniquely combine to provide unmatched resistance to chemicals, not to mention the industry’s finest long-term flexibility in any climate – critical keys to membrane reliability.

The Proper Amount of Elvaloy. FiberTite® exceeds all of the physical property requirements of ASTM Standard D6754-02. Perhaps even more impressive – FiberTite is the only membrane that meets the ASTM polymer content definition for Elvaloy®. Simply using Elvaloy in a formula does not automatically ensure that the membrane will provide the best protections possible. Although important, Elvaloy is only one component integrated into the complex Seaman formula. Correct integration of the correct amount of various components work together to provide the optimum formula for a long-lasting roof.
