  • Thermal shock durability
  • Ultraviolet radiation resistance

EPDM’s high resistance to wind damage has also proven to be an increasingly desirable attribute. These roof systems can be designed to meet a variety of wind uplift criteria from Factory Mutual, including 1-60, 1-90, and 1-120 ratings and greater, and the stringent code of Dade County, Florida.
