EPDM rubber is fast becoming one of the most widely used synthetic rubbers in the roofing industry; but what is it? Ethylene-Propylene Diene Monomer is a high-density rubber membrane; it has a series of qualities that make it a fantastic and effective choice for rubber roofing. Firstly EPDM rubber is impermeable to water; it’s completely waterproof. This can be said of all reasonable roofing options, but EPDM has other important strengths.
EPDM membranes are an extremely durable roofing option. Firstly, the saturated polymer backbone allows for a strong resistance to weathering in its many forms. The membrane has excellent resistance to high heats and temperature changes, a strength well suited to the temperamental British climate. Moreover, the chemical properties of EPDM result in a very low risk of oxidation and any related damage, as well as providing a high resistance to water, acid and alkali erosion; all key factors in any roofing product, given the frequent exposure to wet weather and the outside atmosphere.
The EPDM membrane is a non-polar elastomer, which affords it a high electrical resistivity. Furthermore, it has flame retardant properties and the highly flexible membrane (capable of up to 300% movement) makes it unsusceptible to physical damage such as tearing and abrasion. These intensely durable characteristics are evidenced by its frequent application in various other tools such as industrial hoses, moisture barriers, electrical insulation and solar panels.
Outside of durability, there are aesthetic benefits to EPDM. It can have a remarkably smooth and level finish, when fitted correctly, making it a much more attractive option than many other roofing membranes. What’s more, it’s simple and easy to install.
