What is PVC?
Roofing Glossary · Materials
Definition
Polyvinyl Chloride roofing membrane — a thermoplastic single-ply material used on low-slope roofs, heat-welded at seams like TPO. PVC is highly resistant to chemicals, oils, and grease, making it the preferred flat roofing material for restaurants and food processing facilities. It is more expensive than TPO but offers superior chemical and fire resistance and maintains seam strength longer.
