Flexion Protection from mother Nature Conklin's Flexion provides a tough, yet extremely flexible, 50-mil barrier between you and the elements. The Flexion System's advanced polyvinyl Chloride (PVC) thermoplastic formulation has been reinforced with Dupont Elvaloy and a 1000 - denier, low wicking fabric, providing superior strength, stability and flexibility over the long haul. The Low-Maintenance Solution Flexion's thermoplastic formulation allows the seams to be heat welded. In addition, maintenance and repair can be done with relative ease because seams can be heated with-out special cleaners or adhesives. Building owners can be confident in the integrity of this protective barrier because these thermoplastic seams are actually stronger than the parent product, assuring a tough, durable and waterproof life. Return on Investment - Now that's "Cool"! Building owners will be pleased to learn that the Flexion System features favorable life cycle costing, a concept foreign to traditional black roofing products available on the market. Flexion's highly reflective surface reflects away 85 percent of the sun's ultraviolet rays, keeping the roof cooler. And, a cooler roof means a cooler work or living space below. In fact, a "Cool Roof" membrane can do something dark surfaced roofing could never do-pay for itself in energy savings in an average of four to seven years!
