PVC (Polyvinyl Chloride) is a flexible, durable plastic membrane similar to TPO but with a longer track record.
- The Pros: It has excellent chemical resistance, making it the preferred choice for restaurants (grease vents) or industrial facilities. Like TPO, it has heat-welded seams and is highly fire-resistant.
- The Cons: It is typically the most expensive single-ply option. Over time, plasticizers can migrate out of the material, causing it to shrink.
This material is an excellent premium choice for Texas buildings, specifically commercial buildings like restaurants. It remains flexible and reflective but comes at a higher price point than TPO.
