Ethylene Propylene Diene Monomer (EPDM) synthetic rubber systems have been the industry leader for nearly half a century and it extremely resistant to weathering due to its ability to withstand low temperatures and the absorption of moisture. The most popular EPDM membrane is black, however, it is also available in white. White EPDM offers more reflectance to UVA and infrared rays but does not provide the resistance to weathering as the black membrane does. The seams are either a liquid applied adhesive or a tape, which is dependent on the skills of the installer. EPDM material can be fully adhered, mechanically fastened, or ballasted.
