EPDM: Ethylene Propylene Diene Monomer (or Terpolymer which is simply a product consisting of three distinct monomers). EPDM is classified as a Thermoset material which means it is either fully-cured prior to being installed or that it cures during natural weathering after installation.
EPDM roofs are single-ply membranes meaning there is only one ply of roofing material, not multiple plies laminated together.
The greatest test of any construction material is how it performs under actual field conditions. Forty years of empirical experience in field applications has shown EPDM to have the roofing industry's longest average service life. Characteristics that contribute to this superior overall system performance include:
- Cyclical membrane fatigue resistance
- Proven hail resistance
- High resistance to ozone, weathering and abrasion
- Flexibility in low temperaturesSuperior resistance to extreme heat and fire
- Thermal shock durability
- Ultraviolet radiation resistance
EPDM's high resistance to wind damage has also proven to be an increasingly desirable attribute.
Architects, roof consultants and contractors have come to depend on EPDM's time tested, long-term performance |
