Single Ply Membranes Thermoset Roof Membranes

Ethylene Propylene Diene Monomer (EPDM) or "Rubber" EPDM materials have been used as a roofing material here in the United States since the early 1960's. EPDM is a synthetic rubber material that is formulated with extensive flexibility for use as a membrane sheet roofing. EPDM is manufactured as a vulcanized (cured) membrane. Uncured EPDM is manufactured for use as a flashing material. EPDM can only be bonded to like material with an adhesive when making seams. This adhesive can be seam tape and some liquid adhesives. EPDM membranes range in thickness of .045mils to .120mils. Only fully cured EPDM will bond together creating a molecular linkage. EPDM membranes exhibit good resistance to ozone, UV rays, weathering, and abrasions. EPDM has good low temperature flexibility. EPDM is resistant to some acids and solvents. On the other hand exposure to animal fats, vegetable oil and petroleum based products should be avoided.
