Single Ply Roofing PVC

There are several situations where a PVC might be more appropriate than other roofing solutions. Although good water drainage is desirable in all rooftop situations, it may not always be present. In these "dead-level" applications where ponding water may occur, over the life of the roof PVC systems will maintain watertight integrity better than TPO systems. PVC has better inherent fire resistance than TPO. Although UL fire ratings can be obtained with PVC and TPO systems, a TPO system may require a more extensive (and costly) assembly than a PVC system to achieve the same fire rating. Mechanically attached PVC systems are easier to handle and seam in cold weather. While many types of systems are heat-weldable, PVC chemistry makes rooftop application viable in all climates year-round. Because the material is easy to handle and weld, PVC manufacturers are better able to prefabricate components and accessories (e.g., stacks, curbs, etc.) in a factory setting. For building owners interested in "Green" issues, PVC roofing membrane can be recycled at the end of its installed life.

PVC membranes have proven their versatility, quality, and low life-cycle costs through more than 40 years of performance on buildings of all types in varying climates worldwide. Building owners and specifiers like the peace of mind that comes from using a product with a long track record of real-world performance. Another key parameter is that PVC retains its weldability for its entire service life, allowing new membrane to be welded to the older membrane at any time. Fire performance is also a critical performance criterion in a roofing system. Because PVC membranes are inherently fire resistant, they outperform other roofing systems in resisting the spread of flames.

PVC is a technology backed by 30 years of proven history, with a stable, consistent formula and established installation techniques. Because of PVC's easy-to-weld qualities, manufacturers are able to prefabricate many of the membrane-based roofing components and accessories used to complete roof installations. PVC and TPO systems can be heat-welded on the rooftop, but field welds on PVC systems are more easily inspected — by contractors and Q/A personnel — to assure the quality of the welds.

PVC membranes are versatile and therefore lend themselves many different applications. For example, there are PVC roofs that simulate metal roofs as well as solar-integrated roofing systems that combine PVC membranes with flexible solar panels. In addition, there are PVC membranes available with a factory-applied adhesive that provides a zero-fume and volatile organic compound (VOC)-adhered roof. Because of the factory application of the adhesive, there is also tremendous labor savings for the roofing contractor in the installation. PVC membranes are also used for plaza deck and green roof applications and are the only membranes available that have passed the most stringent tests for root resistance, including the German FLL and Swiss SIA 280 standards. Finally, a new non-penetrating membrane attachment system is being introduced that uses induction heating to weld the PVC membrane to vinyl-coated plates used in the mechanical attachment of the underlying insulation. This unique system will provide labor savings to the roofing contractor and unique design benefits to the specifier and building owner.
