Products / WeatherBond Cool Gray EPDM

A 60 mil non-reinforced, homogeneous gray EPDM sheet with no internal scrim, made by extrusion in seamless 10 foot widths and lengths up to 100 feet, with optional Pre-Applied Seam Tape, used mainly in fully adhered systems. The data bulletin pitches it for markets where heating and cooling costs are more balanced, offering some reflectivity with less glare than white roofs, and lists an initial SRI of 55 (47 after three years), 540% elongation, zero fungi growth under ASTM G21, and manufacture in Carlisle, PA. Its closing note says the membrane meets or exceeds ASTM D4637 for Type I non-reinforced white EPDM.
