The main component of Firestone EPDM Roofing Systems is Firestone RubberGard EPDM membrane, a single-ply synthetic rubber roofing membrane made of ethylene – propylene – diene terpolymer, mixed with carbon black, oils, curing agents and processing aids. It is calendered into large sheets and then vulcanized.
This results in a material that has a high resistance to ozone, UV radiation, extremes of both high and low temperatures, and ultimately ageing. Firestone RubberGard EPDM is available in large panel sizes up to 15 m in width and 61 m in length resulting in fewer field seams and less installation time. It remains highly flexible from -45° C and can also elongate over 300% to accommodate building movements. Besides commercial and residential roofing applications, Firestone RubberGard EPDM membranes are also used for other waterproofing applications in the construction industry, such as below grade waterproofing, curtain walls and masonry thru-wall flashing.
