Products / JM EPDM

Johns Manville's cured, nonreinforced ethylene propylene diene monomer (EPDM) single-ply membrane for commercial low-slope roofs, available in 45, 60 and 90 mil sheets. Fully extruded rather than calendered, yielding fewer air voids, more uniform thickness and smoother sheets, with UV-stabilization for outstanding ozone and weather resistance.
