WHAT IS IT?
EPDM (Ethylene Propylene Diene Monomer) is a rubber material whose principal components consist of the compounds ethylene and propylene. A flexible rubber matrix forms when a small amount of diene is added to the mix. The standard color for this membrane is black; however, it is available as a special order in white depending on the manufacturer.
WHY USE EPDM ROOFING SYSTEMS?
The EPDM polymer enables the membrane to respond to stress and then recover its shape. This elasticity of the thermoset EPDM membrane gives it the proven durability through a wide range of temperatures and conditions that are present during the lifetime of the roof. EPDM is a lightweight single-ply membrane which is ideal for retrofit systems without adding excessive weight to the roof deck.
