EPDM (Ethylene propylene diene terpolymer) is a type of single ply rubber roofing membrane that has been used in the low-slope commercial roofing industry for over a half century. There is a strong demand for EPDM in construction, but it is also widely used in many other industries. EPDM has become the standard for single-ply roofing systems worldwide, due to its extensive list of benefits. EPDM Benefits of EPDM EXCEPTIONAL DURABILITY High resistance to UV radiation, ozone, harsh temperatures and ultimately aging. RAPID AND EASY INSTALLATION Large panels are installed using primers and self- adhesive products. No flames or electricity required. LOW LIFE CYCLE COSTS Little or no maintenance required. One of the lowest roof life cycle costs thanks to EPDM membrane’s decades long service life. HIGH FLEXIBILITY AND ELONGATION IN ANY CLIMATE Elongates over 300% to accommodate building movements in climates worldwide. Proven performance in Canadian winters at -45 °C and in tropical Madagascar climate at +45 °C. SUSTAINABLE AND ENVIRONMENTALLY FRIENDLY Inert material with limited environmental impact during manufacturing, installation and use. The membrane is fully recyclable. EPDM global warming potential 6.93 kg CO 2 /sq.ft. Life-Cycle Assessment, or LCA, of the long-term environmental impact of low slope roofing systems shows EPDM has the lowest environmental impact.

In the construction industry it is used primarily for roofing. Some of the other applications include: Subsurface storm water management Lining for wetlands, ponds and canals Geomembranes for critical containment applications Decorative ponds and water features Masonry & window flashing Water Reservoirs Geomembranes Landscaping Features Thru-wall Flashings Water Management SERVICE LIFE OF 50+ YEARS “Evaluation of the useful life of EPDM roofing membranes” study in 2004 by the German Institute of Synthetic Materials pegged the life span of EPDM membranes at well over 50 years. LOW ENVIRONMENTAL IMPACT Greenpeace and the magazine “Green Building Digest” rank EPDM as the top “low impact membrane”. NO CRACKING EPDM showed no signs of aging after 20 years of exposure under equatorial sun exposure in EMMA tests. Independent studies The in-depth study has shown that most 30-year EPDM roofs are still in excellent condition today, suggesting many years of remaining service life. 30 YEARS LATER PHYSICAL CHARACTERISTICS ALMOST INTACT EPDM A Long Term Roof System Service Life Study conducted by the ERA put to test EPDM roofs installed in the 1980s throughout North America. Samples were tested for: Elongation (%), Tensile (psi), Thickness XD (in), Thickness MD (in) and Factory Seam Strength (psi). * For in-depth research papers on performance of EPDM roofs, please visit www.EPDMroofs.org * SOURCE: EPDMroofs.org Firestone’s RubberGard TM fully adhered EPDM, installed in 1981 on C.C.S.D. 220 in Barrington, IL.
