Standing the test of time.
For roofing materials engineered to withstand the test of time even under some of the toughest conditions, look no further than Johns Manville PVC roofing systems. Johns Manville PVC is a flexible, thermoplastic membrane manufactured using an ultraviolet-resistant polyvinyl chloride. Johns Manville PVC ensures retention to deliver a pliable and durable sheet with excellent weathering characteristics and resistance to harsh chemicals and industrial pollutants. Johns Manville PVC roofing membranes are an ideal long-term solution for roofs that demand high performance at a lower life cycle cost.
Johns Manville PVC Roofing Systems
- Advanced Solid Phase Polymer Formulation
Uses the optimal amount of DuPont™ Elvaloy® KEE (Ketone Ethylene Ester) polymer to ensure plasticizer retention, extend roof life, and reduce maintenance costs.
- Patented Aramid-Reinforced Edge
Aramid fiber is woven into the fastening side of all full rolls of PVC membrane.
- Non-wicking Reinforced Polyester Scrim
Our fully integrated manufacturing process adds tensile strength and toughness. Due to the non-wicking edge, sealant is not required.
- Excellent Chemical Resistance
JM PVC is inherently resistant to oils, air conditioning coolants, fuels and grease.
The Johns Manville PVC formulation uses a solid plasticizer that bonds with the PVC to provide consistent plasticizer retention. This maintains high flexibility and durability throughout the life of the roofing system.
Wide Array of Applications
Polyester reinforcements allow the PVC membranes to be used in either mechanically fastened or fully adhered systems. This provides building owners a broader range of solutions tailored specifically for the building site and weather conditions. Other PVC membranes reinforced with fiber glass have low tearing strength and may be used only in fully adhered systems, greatly reducing roofing options and increasing cost.
High Manufacturing Quality Standards
The Johns Manville PVC formulation has been produced by the same manufacturer for over 25 years, with proven field performance. Johns Manville’s product engineers are dedicated to ensuring quality control, continued testing and the development of innovative and enhanced products.
Lowest Commercial Life Cycle Cost Compared to Other Brands
In a Durability and Cost survey presented by the Roof Consultants Institute, Elvaloy® PVC had a life cycle cost of $0.37/sf/year. Both initial costs and operating costs drive decisions when selecting roofing membrane types, so this information is critical to making an informed evaluation.
Superior Long-Term Solar Reflectance
Roofing membranes that remain white longer have better long-term energy efficiency.
Johns Manville PVC membranes have a three-year reflectivity value of 70% and an SRI (solar
reflectance index) of 84%. Johns Manville PVC is also a viable for solar photovoltaic applications.
Resistant to Chemicals, Oils, AC Coolants, Fuels & Grease
Restaurants and food processors are perfect examples of ideal Johns Manville PVC installations because of the inherent chemical resistance provided by the membrane’s chemistry. A study conducted by SGH Consulting Engineers found that PVC with DuPont™ Elvaloy® KEE is the most resistant of single ply membranes.
