Learning Objectives:

  1. Describe the key physical properties and the different components of a single-ply membrane that are critical to PVC performance.
  2. Summarize the importance of plasticizers as it relates to the performance of PVC and PVC-KEE.
  3. Cover the types of projects that benefit from the characteristics of PVC over other types of roof membranes.
  4. Review the sustainability properties of PVC compared to other roof membranes.


As an IACET Accredited Provider, BNP Media offers IACET CEUs for its learning events that comply with the ANSI/IACET Continuing Education and Training Standard.

Thermoplastic roof membranes are the most common roof covering in the U.S. That category covers both PVC and TPO membranes. In this presentation, we will cover exactly what can be expected of PVC roof membranes and the differences among PVC, PVC-KEE and TPO. This will lead to an in-depth discussion of which projects benefit most from the unique properties of PVC and PVC-KEE membranes, including specific case studies. Finally, attendees will leave understanding what key properties should be put into a specification to ensure performance and how PVC can help support sustainability goals for a project.
