EPDM Rubber 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. EPDM continues to be a top choice of architects, roof consultants and contractors for both new construction and replacement roofing projects. 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 EPDM’s high resistance to wind damage has also proven to be an increasingly desirable attribute.
These roof systems can be designed to meet a variety of wind uplift criteria from Factory Mutual, including 1-60, 1-90, and 1-120 ratings and greater, and the stringent code of Dade County, Florida. Architects, roof consultants and contractors have come to depend on EPDM’s time tested, long-term performance. – See more at: http://www.epdmroofs.org/what-is-epdm/why-epdm#sthash.5X3KQ3VD.dpuf
Our TPO roofing system gives you the option of a reliable, cost-effective roofing solution. Our current membranes are reinforced with a polyester fabric and manufactured using an ultraviolet-resistant thermoplastic polyolefin formulation. TPO roofing comes in several thicknesses and has been designed for ease in installation. And for your convenience, systems can be installed fully adhered or mechanically fastened. We also offer a complete line of accessories, sealants and adhesives to help ensure a waterproof installation.
Our TPO roofing materials are formulated using the best available technology and designed for long-term roof performance in all conditions. We reinforce our TPO membrane with polyester fabric to provide excellent wind uplift resistance, puncture resistance and finished physical properties. And our TPO formulation was developed to allow for extreme pliability, flexibility and weldability during installation. Along with such installation advantages, our TPO’s state-of-the-art formulation helps our product to resist extreme weather conditions, including ultraviolet radiation and high surface temperatures
Benefits of TPO Roofing
One of the factors that makes TPO roofing attractive both in residential and commercial construction is its reasonable cost. TPO offers many of the same benefits as PVC roofing, such as hot-air weldable seams and energy efficiency, but at a lower cost.
Fits different home styles
Many homeowners appreciate the fact that TPO is manufactured to look great on many different types of homes. TPO is available in white, light grey and black reflective color options. Now you do not need to get a white roof to enjoy the energy saving and reflective properties. Latest technologies enable all colors of TPO roofing membranes to be UV resistant and “cool”.
In comparison to other thermoplastic membranes, TPO resists mold growth, dirt accumulation, tears impact and punctures. It is made to be flexible and can allow for a home’s or building’s movement or settling. Reinforced TPO membranes can handle a building’s thermal expansion and contraction more effectively than other single ply roofing products.
Ease of installation
In general TPO membranes are manufactured with wider sheets and are light weight. This means that the material is easier to install and there is less seams. Less work and time associated with the installation translates into direct savings for you for the cost of installation.
The energy efficiency of TPO roofing membranes makes them highly attractive to home owners who want to have the benefits of savings on their cooling costs as well as help the environment by reducing the carbon footprint. TPO’s membrane’s white reflective surface exceeds the EPA’s ENERGY STAR requirements and white, tan and gray are listed with the Cool Roof Rating Council. This means that having a TPO roof on your home or building will keep the interior thermally comfortable on hot summer days while reducing your air conditioning costs.
EPDM membrane formulations have remained relatively constant for over 50 years, with roof systems installed in the 1960s still performing well. Even so, EPDM manufacturers remain committed to continuous product innovations. In response to technological advancements, membrane research and contractor requests for more ergonomic products, EPDM 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 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 roof system installation and performance.
