Navigating the world of PVC roof membranes can be complex due to two distinct ASTM specifications and variations in membrane composition, particularly those including the KEE plasticizer. When you factor in differences in chemical resistance performance, accelerated aging testing, and overall durability expectations, choosing the right membrane can be a real challenge.
This session will help you cut through the confusion. Join us for clear definitions and performance insights for PVC, PVC KEE, and KEE membranes. You'll leave with precise, actionable specification language to ensure the roofing membrane installed on your project delivers the intended long-term performance.
Learning Objectives
- Learn how to differentiate between PVC, PVC KEE, and KEE membrane types (ASTM D 4434 types II, III, and IV, and ASTM D 6754) based on composition and properties.
- Explore the critical role of plasticizer in long-term PVC membrane performance and chemical resistance.
- Compare accelerated aging, chemical resistance, and impact resistance results from various membranes.
- Discover performance specification language for use in specifying the best PVC or PVC KEE membrane for a given project.
