As a vulcanized (thermoset) elastomer, how does EPDM differ from other types of single-plies (i.e. PVC, TPO, single-ply/non-vulcanized elastomer?)

March 5, 2018

EPDM membrane is a vulcanized/thermoset membrane that has been fully cured in the manufacturing process prior to shipment and delivery to the job site. With aging, EPDM membrane will not leech or emit hazardous chemicals. Unlike non-vulcanized elastomers that may begin curing in the field once exposed to moisture and heat, EPDM membrane has no shelf life. Its physical properties remain stable, which makes repairs much easier in the unlikely event of cuts or tears.

BALLASTED EPDM ROOFS

The EPDM (ethylene propylene diene terpolymer) single-ply rubber roofing membrane has been an appealing choice of the low-slope commercial roofing industry for over 40 years.

The number one roofing choice of architects, roof consultants and contractors for both new construction and replacement roofing projects according to market surveys from Building Design and Construction, and Roofing/Siding/Insulation magazines, and the National Roofing Contractors Association (NRCA).
