Longest Lasting Product In The Industry...
Bar None

Sus-tain-a-ble [suh-stey-nuh-buhl] adj.
Pertaining to a system that maintains its own viability.

Characteristics that contribute to EPDM's overall system performance include:
• Long-lasting performance
• Flexabilty
• Outstanding weathering characteristics
• Unmatched resistance to ozone, UV radiation and
cold cracking
• Dimensionally stable
• Limited environmental impact
• Low life-cycle cost

Longest Average Serviceable life:
As environmentalists and code regulators place more emphasis on the sustainable performance of building materials, EPDM continues to be the commercial roofing material that stands the test of time. 45 years of empirical experience in field applications has shown EPDM to have the commercial roofing industry's longest average service life, according to the latest study provided by ERA (EPDM Roofing Association). ERA tested installations 28-32 years of age. The study shows that all of the aged EPDM roof samples taken have physical characteristic properties above or just below the ASTM minimum properties required of newly manufactured 45-mil EPDM membrane, and estimated them to exceed 40 years of serviceable life.

Weathering Characteristics:
Weatherability is a key reason why more EPDM commercial roofs continue to perform better than any other single-ply membrane. “From a weatherability standpoint—mil for mil—EPDM has proven to be one of the most cost-effective membranes available today,” - Rene Dupuis, president of Structural Research Inc., Madison, WI.

Besides its legendary weatherability, EPDM is dimensionally stable, yet is very flexible expanding and contracting with building movement. This allows the membrane to be used successfully in a variety of climates. Unlike Thermoplastics, EPDM is virtually immune to ozone, UV radiation and cold cracking. The material does not rely on plasticizers for its flexibility, so there’s no danger of the membrane becoming brittle from plasticizer loss down the road making it a Long-Lasting Performer. EPDM is available in a wider variety of thicknesses (0.45 to .090 mils) and widths (up to 50' x 100') than thermoplastic membranes.

Furthermore, recent research shows that EPDM has other desirable performance characteristics that dove tail nicely with the nation’s need for more environmentally friendly and durable low-slope roofing systems. For example, over the last year or so, research studies from the U.S. Department of Energy have found that: Buildings in certain climate zones in the U.S. can save more energy with a dark colored EPDM roof than a white thermoplastic membrane, as cool roofs do not perform equally everywhere.
