Components of a Rubber Roofing System (EPDM)
EPDM continues to be the roof system of choice for architects, engineers, roof consultants, contractors and building owners. EPDM offers versatility, product varieties and availability, environmental benefits, contractor knowledge and familiarity and cost effectiveness. In short, EPDM's popularity is growing because "EPDM Continues to Perform." From the arctic reaches of northern Alaska to the humid climates of Central America, from the deserts of the Middle East to the continuous wet seasons of the Pacific Northwestern U.S., EPDM's performance is living proof that quality roof system design and installation continue to stand the test of time.
EPDM is an elastomeric polymer synthesized from ethylene, propylene and a small amount of diene monomer, compounded with carbon black, processing oils and various cross-linking and stabilizing agents. As a thermoset membrane that recaptures its shape after stretching, EPDM maintains its physical properties for decades. EPDM is manufactured in large sheets varying in width from 10 feet to 50 feet, and features lengths up to 200 feet. The membrane can be reinforced and comes in thicknesses of 45, 60, 75 and 90 mils (thousandths of an inch). Back to top
