Why choose PVC?
When compared to alternative roofing membranes, thermoplastic polyvinyl chloride (PVC) offers superior resistance to grease, oil, animal fats, and chemicals. It is the preferred roofing system when chemical resistance is required.
Why choose KEE?
Known as KEE or PVC KEE, PVC enhanced with DuPont™ Ketone Ethylene Ester (KEE) is a premium membrane due to its ability to provide maximum chemical resistance against the harshest chemicals and outperform standard PVC membranes in nearly every performance attribute when exposed to the same roofing conditions.
Refer to the chart below outlining the critical membrane performance attributes and how they differ.
