ENERGY STAR – Flat Seam

ENERGY STAR

A registered trademark of the U.S. government. The ENERGY STAR Program* represents a voluntary partnership between businesses and organizations and the federal government to promote energy efficiency and environmental activities. ENERGY STAR labeled roof products are reflective and lower roof surface temperature by up to 100F., decreasing the amount of heat transferred into a building. ENERGY STAR labeled roof products are designed to help save money on utility bills and reduce energy waste. Ninety percent of the energy in the United States is generated by burning fossil fuels, which creates the air pollution associated with smog, acid rain, and global climate change. By reducing the amount of energy needed to cool buildings, ENERGY STAR labeled roof products help to reduce the production of these air pollutants. Additionally, reflective roof products can help reduce the “heat island effect,” a phenomenon in which cities can be 2C. warmer than the surrounding countryside. Such heat islands occur, in large part, because many buildings and paved surfaces are designed with dark materials that absorb heat from the sun. This heat is released at night, causing the air temperature to remain high. The resulting elevated temperature leads to an increased demand for air conditioning in buildings, increased fuel use for vehicle air conditioning, increased levels of smog, and associated increased levels of heat-related and smog-related health problems. Installing reflective roofs helps reduce the heat island effect, decreasing the amount of smog in the air and benefiting the entire community.


Fire Resistance

The ability of a roof top material to act as a barrier to the spread of fire and confine it to the area of origin. There are established test procedures for external fire exposure to classify roof systems into Class A, B, or C ratings. Underwriters Laboratories test method 790 established this procedure which ASTM adopted and named ASTM E-108. Therefore UL 790 and ASTM E-108 is the same test with different names. Factory Mutual and Warnock Hersey both use ASTM E-108 as the primary test for fire resistance.


Flat Seam

Is a term used to describe when two metal panels are joined in a shingle fashion. The two panels can either be overlapped and fastened or folded and interlocked. Flat seam systems are made out of metal, which makes the roof durable, 100% recyclable and very low maintenance.
