half of U.S. schools have indoor air quality problems, which are blamed for reducing student performance on tasks requiring concentration, calculation and memory. According to GEI, children are more at risk for environmental toxins than adults. They consume more food, water and have higher inhalation rates per pound of body weight than adults, which means they are more susceptible to pollutants in the environment than adults are, and those pollutants can be more damaging to their health. To account for inhalation exposure to young children with greater sensitivities, GEI applied a body burden correction factor to current allowable emission levels from indoor materials and furnishings. The exposure to individual chemicals was also adjusted to allow no greater than 1/100 of currently published Threshold Limit Values or no greater than one-half of California's Chronic Reference Exposure Levels, whichever is lower. In many cases, the safety factor results in the most stringent requirements for an extensive range of volatile organic compounds. In addition, limits on emissions of phthalates were established to define low-emitting materials for educational and learning/play environments. "As a provider of optimized green solutions, we are pleased to install air- handling products that are certified for use with young children," says Jeff Phillabaum, President, Hill York, the leading air-conditioning contractor in South Florida since 1936. The company specializes in commercial and institutional projects including educational, governmental, healthcare, recreational and religious facilities, and green building solutions are often a necessity. "Our customers count on Hill York for cost-effective, energy-efficient and performance-managed cooling solutions that make life more comfortable," continues Phillabaum. "We have been installing Owens Corning ducts with confidence for many years but it is wonderful to also have independent third- party verification of the product's contribution to indoor air quality." Dr. Marilyn Black, Founder of GEI, said: "The Institute applauds Owens Corning in their continued commitment to furthering our mission of improving indoor air quality for children in schools. Products such as Owens Corning duct board are certified by GEI so that consumers can rest assured that their homes, work places and schools are healthy and safe environments." For more than 40 years, Owens Corning fiberglass duct board, duct liner and duct wrap insulation have been contributing to energy conservation, noise control and indoor air quality performance in heating, ventilating and air conditioning systems serving residential and commercial buildings in all parts of the country. The primary benefits of fiberglass ducts are acoustic performance and energy efficiency. Fiberglass ducts reduce air leaks eight times better than unsealed and uninsulated metals ducts, and fiberglass ducts are 75 percent more efficient than unsealed and uninsulated metal ducts. Both claims are based on data compiled by the North American Insulation Manufacturers Association, a trade association of manufacturers of fiberglass and other mineral wool insulation products. Other product features and benefits of fiberglass ducts include:
