Description Energy and Be t Environment
JM PVC is a flexible, thermoplastic membrane manufactured using ENERGY STAR® Pass Reflectivity: 0.86
an ultraviolet- resistant polyvinyl chloride and an Elvaloy® KEE Title 24 Pass Reflectivity: 0.86 Emissivity: 0.86
(ketone ethylene ester) formulation. JM PVC membranes are LEED Reflectivity: 0.86 Emissivity: 0.94
reinforced with a non - wicking polyester fabric. JM PVC membranes Recycled Content
provide excellent weathering characteristics, high tensile strength Post Consumer: 0% Post Industrial: 2.5%
and long -term flexibility. JM PVC membranes also have excellent Producing Location: Pawtucket, RI
resistance to harsh chemicals and industrial pollutants.
Results shown are for the initial reflectivity and emittance for white membranes;
Use emissivity values for Title 24 are tested per ASTM C 1371; LEED emissivity
values are tested per ASTM E 408.
JM PVC membranes can be installed in new, reroof (tear -off) and
