(PRWEB) August 8, 2005
As the heat wave of 2005 continues throughout the United States, more and more homeowners are looking for ways to keep their homes cool without running up sky-high air-conditioning costs. The best solution, of course, is to prevent heat from entering the home in the first place Â the approach that enables todayÂs new Âcool roofÂ technologies to help reduce the cost of air-conditioning a home by up to 20 percent.
ÂHomeowners in virtually all parts of the country are coping with record high temperatures this year Â which means they could benefit tremendously from a roofing system that keeps the attic cooler,Â said Tony Chiovare, president of Custom-Bilt Metals, a long-time leader in the painted metal industry. His company was one of the first manufacturers to incorporate cool roof technology in its metal shingles, metal shakes and standing seam metal roofing products.
ÂWe believe this summerÂs heat wave will make more and more homeowners realize how critical their roofing system is to the overall comfort and efficiency of the home,Â Chiovare said.
Chiovare pointed to the results of one recent demonstration project, in which metal shakes coated with Custom-Bilt MetalsÂ ULTRA-Cool™ coating were found to reduce the amount of heat penetrating into a homeÂs attic by as much as 36 percent, offering significant savings in the energy required to cool the homes.
ÂBecause less heat penetrates the roof, the attic remains cooler and, in turn, the heat leaking into the air-conditioned home drops,Â Chiovare said.
Custom-Bilt MetalsÂ ULTRA-Cool coating is a high reflective finish developed by BASF CorporationÂs Industrial Coatings Division. Like other cool roof technologies, the ULTRA-Cool finish works by reflecting a greater amount of the sunÂs infrared energy, which accounts for more than half of the solar energy striking the roof surface.
Most painted metal roofs reflect about 5 to 20 percent of this energy, but cool roof coatings can increase this reflectance level to nearly 60 percent, according to tests by Lawrence Berkeley National Laboratory and Oak Ridge National Laboratory. Yet since infrared energy is invisible, the roof color is unaffected
ÂEach additional percentage point of reflectance reduces metal temperature by one degree, so the difference in temperature can be very dramatic, especially in medium to darker colors,Â Chiovare said. A metal roof coated with a cool roof finish can be as much as 55 degrees cooler on a sunny day, he noted. These cooler roof temperatures can produce as much as 20 percent savings in air-conditioning costs.
ÂThese important field tests demonstrate the tremendous energy-saving potential that cool roof technology can provide,Â said Chiovare.
In addition to energy savings and lower utility bills, he noted that the ULTRA-Cool coating also provides other advantages to building owners including greatly improved fade resistance.
ÂOver 10,000 hours of accelerated exposure has proven these roofs are significantly more fade resistant than conventional roof coatings,Â he said. ÂAnd, since these roofing systems remain so much cooler in even the hottest weather, the amount of heat expansion and contraction is also reduced, which will add to the roofÂs durability and longevity.Â
Chiovare said the national laboratoriesÂ tests of his companyÂs roofing systems, coupled with this summerÂs heat wave, have combined to convince him of the potential importance of cool roof technology.
ÂMetal roofing is already widely recognized for offering so many benefits, such as greater fire resistance, lighter weight, seamless integrity, color choice and longevity,Â he said. ÂThese benefits are now enhanced by the environmental and cost-saving advantages offered by ULTRA-Cool coatings.Â
