EPDM rubber is a class of synthetic rubbers made primarily from EPDM polymer. EPDM rubber share a chemical structure that gives them an extra ordinary resistance to Heat, Cold, Sunlight and air pollution, ideal characteristics for a roofing membrane. It is ideal for roofs with poor drainage or where the water proofing is to be covered by gravel, soil, decks, or pavers. In addition, since it is fully UV stable, it can be used for fully exposed applications.
