EPDM rubber is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide. CALL US ON 01691 674497
Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas. EPDM rubber roofing is available in both black and white, and is sold a broad variety of widths, ranging from 7.5 feet to fifty feet, and in two thicknesses, 45 and 60 mils.
EPDM rubber roofing can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specially formulated tape.
EASE ON INSTALLATION
EPDM rubber roofings application methods (ballasted, fully adhered and mechanically attached) allow the membrane to be installed on slopes with positive drainage up to and including vertical applications for fully adhered systems.
Good roofing practice always includes provisions for proper drainage for any type of roof system and in most cases, is dictated by local building codes. Because EPDM rubber roof remains stable over a wide range of temperatures, it allows for year-round installation in all climates.
HISTORICAL TIMELINE
EPDM rubber roofing membrane formulations have remained relatively constant for the past 40 years, with roof systems installed in the 1970s still performing well. Even so, EPDM rubber roofing manufacturers remain committed to continuous product innovations. In response to technological advancements, membrane research and contractor requests for more ergonomic products, EPDM rubber roof accessory products continue to evolve in order to meet the demands of the industry.
The innovation of seam tapes in the 1980s to replace liquid adhesives has resulted in reduced reliability on contractor workmanship, greater productivity for the contractor and enhanced performance for the roof system and building user. Self-adhering components (components that have factory-applied adhesive tape) have increased rubber roof system quality, especially in more problematic areas such as flashing installations.
Installation equipment has evolved as well. Ergonomic innovations have reduced crew force fatigue and have enhanced EPDM rubber roof system installation and performance.
Following over 15 years of off-market testing to verify performance, 90 mil EPDM rubber roof membranes have recently been introduced into the market. This highly puncture resistant and tough membrane offers the thickest layer of monolithic waterproof protection in the roofing industry. CALL US ON 01691 674497
The 90 mil EPDM rubber roof systems are redefining the roofing industry and the expectations of architects, roof consultants and building owners. Thirty-year warranties based on historical performance are now available. This is the only long-term performance guarantee in the roofing industry, and can include warranty coverage for punctures, hail and wind speeds up to 100 mph.
White EPDM rubber roofing combines the high-performance standards of traditional EPDM rubber roofing with a highly reflective, environmentally friendly surface designed to cut energy costs. In addition to the oils and the polymers used to make an EPDM rubber membrane, another ingredient is added to the mix to enhance UV resistance. With white membrane titanium dioxide is typically used to reflect UV rays and prevent it from attacking the polymer. When used appropriately, usually in warm climates, white EPDM rubber roofing can reduce air-conditioning costs without sacrificing durability of the roofing system. Because of its reflectivity, white EPDM rubber roofing is installed using mechanically attached or fully adhered systems.
