Spotlight on Johns Manville PVC Membrane Roofing


In our recent posts, we covered the features and benefits of Johns Manville EPDM  and TPO membrane roofing . As we continue our series on commercial membrane roofing systems available from Johns Manville, we turn our attention to their PVC membrane roofing. Their PVC roofing has a track record of 25+ years, having been introduced in 1988 and commercialized in 1990. Other roofing membranes from Johns Manville that we’ll be walking readers through in upcoming blog posts are their SBS, APP, BUR and Liquid Applied solutions. We will then touch on commercial roofing products from Firestone.

PVC Basics and Benefits
The Johns Manville website describes their PVC membranes as “built to withstand the test of time” and “made to resist the toughest weather conditions and chemicals.” Their formulation history report states: “JM’s PVC has worked for more than 25+ years in all U.S. climate conditions, with no membrane degradation failures.” Here are a few additional PVC benefits shared on the Johns Manville website and other sources:

  • com states: “Probably more than any other membrane system, PVC trim from the manufacturing process can be 100 percent recycled, and post-consumer membranes are already being returned and recycled back into new membranes.” Additionally, Professional Roofing magazine reports: “In the single-ply category, PVC roof membranes stand out as a noteworthy success story.”
  • JM PVC with Dow Elvaloy® KEE and JM PVC SD Plus thermoplastic roofing membranes are “manufactured using an ultraviolet-resistant polyvinyl chloride. Utilizing a polyester fabric reinforcement allows for systems to be both mechanically attached and adhered.”
  • PVC membranes “deliver a pliable and durable sheet with excellent weathering characteristics and resistance to harsh chemicals and industrial pollutants.”
  • com also mentions “PVC membranes are weldable throughout their lifetime, remaining thermoplastic.” This is a tremendous benefit when roof modifications are needed or desired.
