Yazoo Mills upgraded the roof on the two oldest portions of the plant in New Oxford.  The new roof utilized an EPDM (Ethylene Propylene Diene Monomer) system and added two additional layers of insulation for a total increased R-value of R-21.  This high-performance synthetic rubber compound provides outstanding weathering characteristics in all climates and reduces building energy costs.  The EPDM weatherproofing membrane has a high resistance to ozone abrasion, ultraviolet radiation and hail damage.
