Polyvinyl chloride (PVC) has been used in North America as a single-ply roof membrane for more than 40 years. Because of the longevity of PVC and its history of performance, PVC roofs have a lower roof replacement rate compared to other single-ply membranes. This course discusses how PVC is manufactured, its features and benefits, and comparisons between its performance and that of other thermoplastic single-ply membranes.

Upon completion of this course, the Learner should be able to:

• Discuss the history of PVC and its application in building and construction.
• Describe how PVC single-ply roof membranes are made and how PVC manufacturers have reduced release of toxic emissions to the environment, improved worker protection from toxins, and eliminated toxic metals in stabilizers.
• List PVC roofing’s performance and safety characteristics, including high solar reflectance index (SRI) values, class A fire resistance, chemical resistance, and longevity.
• Describe critical performance criteria for single-ply membrane roofing, including resistance to wind uplift, thermally induced movement, and weathering and the related ASTM standards.
• Describe appropriate substrates, installation methods, and applications for PVC single-ply roof membranes.
