The Flex TPO thermoplastic single ply system is based on advanced polymerization technology that combines the durability and weatherproof properties of ethylene-propylene (EP) rubber with the heat-weldable capability of polypropylene. This membrane is specifically formulated for long-term weather resistance without the use of either polymeric or liquid plasticizers. In addition, Flex TPO membranes will not host mildew, bacteria or algae, so that reflectivity remains high, helping reduce air conditioning loads and the urban heat island effect. They are also made without plasticizers or chlorinated compounds for a superior environmental roofing solution. Flex TPO comes in wide sheets to help make installation faster and easier on new roofing and re-roofing applications, resulting in fewer seams and less material.

Commercial low-slope roof assemblies over structural decks and compatible insulation where heat-welded seams, wide sheet efficiency, and reinforced TPO durability are required.

Not intended for high-solvent or grease-laden exposure without confirmed compatibility; verify wind uplift assembly ratings, fire classification, and chemical resistance for project-specific conditions prior to specification.

60-mil self-adhered thermoplastic polyolefin (TPO) roofing membrane with heat-weldable seams and a factory-applied pressure-sensitive adhesive. Manufactured in 5- and 10-foot widths (50- and 100-foot rolls). The membrane integrates proven TPO weathering performance with a 100% solids hot-melt adhesive to eliminate VOC and odor concerns. An uncoated selvage edge permits hot-air welded field seams, and a dual-sided silicon-coated release liner ensures controlled, consistent installation.

Fully adhered low-slope commercial roof systems where reduced labor, low-odor installation, and welded seam integrity are required, including projects with VOC or occupancy restrictions.

Substrate must be clean, dry, and approved for pressure-sensitive adhesion; verify ambient temperature requirements during installation and confirm wind uplift and fire-rated assembly compliance prior to specification.

reinforced PVC decking membrane engineered for high-traffic balcony and roof deck applications. Formulated for UV stability, chemical resistance, stain resistance, and integral slip resistance, it functions as both a durable walking surface and a waterproofing layer. The system provides a low-maintenance, exposed waterproof membrane suitable for occupied exterior deck assemblies.

Balconies, terraces, roof decks, podium decks, and other pedestrian traffic surfaces requiring exposed waterproofing and slip-resistant performance.

Not intended for vehicular traffic; confirm structural deck slope and drainage provisions, and verify compatibility with underlying substrates and flashing components prior to specification.

Flex membranes coated with DuPont’s Elvaloy KEE (ketone ethylene ester) provide state-of-the-art performance for thermoplastic single ply roofing systems. Elvaloy KEE, unlike liquid plasticizers, does not migrate out of the membrane, keeping it flexible, workable and tough from the day the roof is installed, even in extreme climates. Its remarkable physical and chemical properties make Flex Elvaloy KEE thermoplastic single ply membranes the ideal choice for roofing systems that are tougher than the elements. Flex membranes based on Elvaloy KEE are ideal for mechanically attached, fully-adhered, ballasted and green roof applications. All membranes are reinforced and are available with smooth backing or fleece backing. Specify Flex Elvaloy KEE with confidence… DuPont Elvaloy KEE makes the difference.
Membrane complies with ASTM D4434 and is listed in FM Class 1-90 assemblies, UL Class A fire-rated systems by Underwriters Laboratories, and CRRC-rated for reflectance.

60, 72, or 80-mil polyester-reinforced PVC thermoplastic membrane with factory-laminated fleece backing, engineered for re-roofing over minor substrate imperfections, splits, or ridges. The fleece layer provides abrasion resistance and separation, often eliminating the need for slipsheets or additional insulation in mechanically attached installations over approved existing roof surfaces.
Suitable for mechanically attached or fully adhered systems; adhered assemblies using Flex WB (water-based) PVC Substrate Adhesive achieve FM Class 1-270 over lightweight concrete, supporting high-rise and coastal applications requiring elevated wind uplift resistance.

Flex PVC flexible single ply roofing membranes are made using special UV inhibitors to provide a proven long-term roofing solution. The permanent, watertight heat-welded bonds are stronger than the material itself, which features Polyester Scrim Reinforcement. Flex PVC provides high performance advantages and exceptional resistance to harsh environments at a lower life cycle cost. Flex PVC roofing systems provide a clean, quick and economical installation with high resistance to fractures, weather elements, extreme temperature ranges and many contaminants. This system provides high strength against breaking and tearing, and resists excessive elongation and sheet deformation during installation. Used successfully for over 45 years in the industry, Flex PVC Single Ply holds the longest track record of successful installations among all types of thermoplastic single ply roofing membranes. All applicable PVC membranes are 100% recyclable at end of life.

The Flex PVC Roof Rib Profile is a proprietary extruded thermoplastic roof system component shape designed to duplicate the appearance of a traditional standing seam metal roof. The Flex PVC Roof Rib Profile and Flex PVC Roof Membranes are available in a wide range of colors to meet the requirements of any building design. The Flex PVC Roof Rib Profile is hot air welded to the surface of the roof membrane which allows for unlimited flexibility in the rib spacing and layout.
