Overview
Polyvinyl Chloride (PVC) membranes offer superior resistance to animal fats, grease, and a wide range of industrial chemicals — making them the specified choice wherever rooftop exhaust or drainage contains contaminants that degrade standard TPO. PVC is also inherently fire-resistant and carries Class A fire ratings without additional surfacing. Like TPO, PVC uses hot-air welded seams for waterproof continuity across the entire field.
Key Benefits
- Resists degradation from grease, oils, fats, and industrial chemicals
- Inherent Class A fire resistance — no additional surfacing needed
- Hot-air welded seams provide watertight, durable lap joints
- Flexible in cold temperatures — less prone to brittle cracking during winter installation
- Long track record: PVC has been in commercial use since the 1960s
- Widely accepted by code in restaurant, food processing, and chemical plant applications
