Single Ply Roof NWL Control Systems

- January 11, 2018 -

Within just a few months after a nationally known single-ply roof membrane was installed on NWL Control Systems 80,000 square foot facility in Beaufort, South Carolina, seams began to fail.

The replacement FiberTite® single-ply roof system was installed after the failed membrane was removed and subsequent thermographic testing showed the integrity of the FiberTite® membrane solved the problem.

High-Performance Membrane Technology Offers Proven Performance and Economy

Using advanced technology, the Seaman Corporation has created economical ways of building into its FiberTite® single-ply roof membrane a level of endurance and performance factors that is well beyond other single-ply roof membranes. The end user benefits from using FiberTite® in that the initial installation cost is very competitive and the proven long term durability provides long lasting value.

For more than 40 years, the Seaman Corporation has been manufacturing single ply membranes that must survive in extremely hostile environments like nuclear waste holding tanks, oil and chemical holding tanks and ponds, mining conveyor belts and inflatable boats. Seaman Corporation is also the world's largest supplier of architectural fabrics to the fabric structure industry where the single-ply membrane functions as the roof itself, rather than just as the water and weatherproofing membrane.

Superior Fabric, Compounding and Coating Technology for Supreme Toughness

Seaman-developed Poly-R® fabric technology and a proprietary ethylene interpolymer alloy (EIP) coating based on Dow Elvaloy® KEE ketone ethylene ester are combined to make the FiberTite® membrane, which is unequaled for total all-around performance. FiberTite® is based on a weft reinforced polyester fabric, not merely a loose scrim supported sheet. Even when punctured, the fabric is engineered to \"rope up\" and keep tears down to just inches rather than major ruptures as is the case with many common membranes. This tough polyester fabric provides excellent dimensional stability and resistance to abrasion and thermal shock damage as well. Its light color reflects heat to facilitate energy savings.

The exclusive FiberTite® priming and coating process forms a molecular bond between the fabric and the coating which eliminate wicking and prohibits the entry of destructive moisture or chemical solutions into the membrane.

FiberTite's EIP coating formulation is an outgrowth of the Seaman Corporation's XR-5 pond liner membrane, which is recognized in the chemical containment industry as the state of the art for chemical resistance. No other single-ply membrane can live up to FiberTite's resistance to such brutal roof-top pollutants as jet fuel (JP-4), hydrocarbons, restaurant and food processing fats and oils, as well as many other common roof-top vented contaminants. The exclusive EIP coating formulation is also superior in resisting direct UV light which can cause blistering and cracking, and eventual fungus and organic attachment.

An Installation System to Match the Membrane

FiberTite® is mechanically attached to the roof deck with Seaman approved fasteners and specifically designed stress plates. The Seaman-designed roof system provides fast, precise and efficient installation for the contractor and minimizes the opportunities of installation error. This patented system has proven itself repeatedly in meeting the expectations of the specifier, roofing contractor and building owner in optimizing the cost/benefit ratio and has earned FM Class I and UL Class A ratings, along with meeting every other major code requirement known.

Factory welded roofing membrane rolls with a patented installation tab system in 10-ft, 15-ft and 20-ft widths by 102-ft length maximize roof coverage and minimize the amount of thermal field welding needed to complete the job. A complete line of installation accessories plus 56-ft by 100-ft long untabbed rolls of FiberTite® membrane are also available. Special length panels and rolls can be made to fit the customer's job requirements.
