COMMERCIAL ROOFING   

The EPDM (ethylene propylene diene terpolymer) rubber roofing membrane has been an appealing choice of the low-slope commercial roofing industry for over 40 years, with more than 500,000 warranted roof installations on 20 billion-plus square feet. Annually, EPDM accounts for over 1 billion square feet of new roof coverings in the United States, and is the most frequently used roofing material in the marketplace. Building Design and Construction magazine and the National Roofing Contractors Association (NRCA) confirmed in their 2002-2003 market surveys that EPDM continues to be the number one roofing choice of architects, roof consultants and contractors for both new construction and replacement roofing projects.

Superior Performance

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 temperatures
Superior resistance to extreme heat and fire
Thermal shock durability
Ultraviolet radiation resistance
