PVC membranes are made from polyvinyl chloride applied over a reinforcing scrim. Available in different colors, white is most commonly used as it offers excellent solar reflectivity. PVC laps are welded together using hot air to create a seemingly conterminous or seamless membrane.
PVC Roofing Systems are among the easiest single-ply roofing membranes to install and heat-weld together. Among the advantages PVC systems provide:
- These systems are able to resist various chemical effluents.
- They provide superior resistance to punctures and tears.
- PVC systems are especially suited for roofs that are exposed to concentrations of grease, oils and many kinds of fuels.
- In areas where acid rain or other forms of acidic outflow is a problem, PVC roofs are the preferred solution.
