The three major chemistries each have a home. TPO leads the market with its balance of reflectivity, weldable seams, and cost. EPDM brings decades of proven history and excellent performance across temperature extremes. PVC is the specialist — its chemical and grease resistance makes it the go-to over restaurants and food service.
