North Central Insulation: EPA Energy Star Roof
EPA Energy Star Cool Roof
EPA Energy Star® Roof Products Program ensures a more prosperous future through the wise use of energy in buildings. The mission is to make new and existing buildings more efficient, comfortable and affordable and our communities more livable.
Some astonishingly simple measures could save the US billions in energy costs - not to mention making the summer in the city bearable. With summers getting hotter and smog increasing, a Cool Roof might be the answer for the 21th century. Our Cool Roof Systems also stop leaks, adhere to most surfaces, are UL listed and have a life that can exceed 20 years.
A Cool Roof is a roof that has a light colored coating which reflects the sun's heat and UV rays. These roofs lower the building temperature and reduce sunlight degradation. Cool Roofs can reduce air conditioning costs, reduce smog and help the environment. In addition to the highly reflected top light colored coat, the 1" SPF layer provides for an R value of 7.0. Roof surface temperatures can be reduced up to 70°F. Air infiltration will be eliminated and electric bills can be reduced by up to 50%.
An "Urban Heat Island" is an invisible dome of hot air that heats cities up to 10 degrees warmer than surrounding areas. The higher temperatures increase air pollution and energy use. Now, NASA scientists are on a new thermal imaging mission to pinpoint who's hot - and who's not, and how we can keep our cool. Also, the warming of the nighttime temperature is due to the Urban Heat Island (UHI) effect, which is the result of two main features of urban areas. First, roofs, roads and paved surfaces store heat during the day, which is then released slowly over the evening due to the thermal properties of the surface materials and the building geometry which traps the heat stored during the day. The second contributing factor to the UHI is due to the artificial heat released into the urban atmosphere by combustive processes from vehicles, industrial activity and the heat that escapes from commercial and domestic air conditioning. About half the U.S. population lives in heat islands!
A highly successful experiment in measuring how cities can keep their cool will be repeated in several U.S. cities this summer. The principle behind the Urban Heat Island Pilot Project (UHIPP) relates to the differences in cooling and heating between the natural and manmade surfaces that make up a city. "Urban forests are important to keeping cities cool," said principal investigator Dr. Jeff Luvall. "What's important are both the extent and arrangement of these forests."
