PVC is made from Polyvinyl Chloride. Simply put, it's plastic, very similar to PVC pipes, flooring, and siding you're accustomed to seeing at the hardware store. In roofing, PVC is combined with a plasticizer to form a flexible, single-ply membrane that can last for decades. PVC single-ply membranes were first installed in Europe in the 1960s and the United States in the 1970s. PVC membranes can be ballasted, mechanically attached, or fully adhered for installation — further adding to their versatility.
A few benefits of PVC membrane include:
- Durability: PVC is chemical, grease, and animal-fat resistant. Heat-welded seams form a watertight bond, and the membrane can stand up to moderate foot traffic.
- Fire resistance: PVC is self-extinguishing. It's the most fire-resistant single-ply roofing membrane available today.
- Sustainability: PVC is a cool roof solution, meaning it can help lower energy costs in hot climates where peak air conditioning loads are a constant concern. PVC is also almost 100% recyclable. Not all types of thermoplastic roofing materials are recyclable.
PVC is an excellent choice for building owners who seek a highly durable, waterproof, and reflective roof.
