What is EPDM?
EPDM is the acceptable abbreviation for Ethylene-Propylene-Diene Terpolymer, a synthetic rubber compound that gives high-performance waterproofing when laid in a single piece of membrane over a flat roof surface.
How long will the membrane last?
The membranes offer unrivalled resistance to UV radiation, ozone, alkali rains and exceptionally high or low temperatures. Studies have demonstrated that genuine Firestone membrane has an expected lifespan of more than 50 years.
Can the membrane be used as a pond liner?
No, the membrane is only suitable for roofs and gutters. EPDM pond liners are available, but are manufactured using a different process to the roofing membrane.
Is the membrane available in different colours?
No, the membrane is only available in slate grey. It can be painted with a suitable acrylic paint in some circumstances.
Can the membrane be ballasted?
Yes, it is possible to ballast the membrane, but you must take care to cover the membrane with a suitable medium, such as rounded washed bank river gravel and/or pavers placed on protective rubber feet.
