OWENS CORNING DEVELOPS NEW TECHNOLOGY FOR FORM INSULATING.

Owens Corning (NYSE:OC), Toledo, Ohio, a world leader in building materials systems and glass fiber reinforcements, has developed new blowing agent technology that will allow the company to manufacture its complete line of foam insulating systems in North America with more than a 70 percent reduction in greenhouse gas emissions and zero ozone depletion.

Owens Corning has already begun the conversion of its foam insulation manufacturing facilities to the new blowing agent technology. The timetable will ensure the full conversion of its North American manufacturing footprint for foam insulation, inclusive of the start-up of a new facility in Gresham, Ore., prior to the Montreal Protocol mandate of 2010.

"The development of this new technology and investment in the full conversion of our manufacturing facilities reflects our long-term commitment to our customers and the growth of their businesses," said Kim Howard, vice president and general manager, foam insulation. "We will continue to look for new technologies that better deliver insulating systems, save energy, protect the environment, and meet our customers' needs."

Owens Corning PINK Foamular(R) and PROPINK(R) Rigid Foam insulating systems save energy and reduce greenhouse gas emissions by providing a durable exterior sheathing that is resistant to damage, provides an insulating value of R5 per inch, and is moisture resistant. Owens Corning foam insulation products are used in above and below grade applications in residential, commercial and industrial markets.

Commitment to Sustainability

Investing in new technology for foam insulation manufacturing is one way that Owens Corning is fulfilling its commitment to sustainability - greening its products, greening its operations, and improving the energy efficiency of the built environment.

"An investment in insulation manufacturing is a long-term investment in energy efficiency and greenhouse gas reduction," said Frank O'Brien-Bernini, chief sustainability officer. "Extruded polystyrene foam board is an important insulation product that meets the market need for efficient thermal performance combined with durability and moisture resistance. Simultaneous with this major technology conversion, we remain focused on further reducing energy intensity and emissions from our manufacturing operations around the world."

In fact, the unit meets Vermont's proposed future emissions level of 0.32 lbs/million Btu heat output.

After March 31, 2008, only outdoor wood furnaces that have been certified by Vermont to meet their standard are allowed to be sold or installed in Vermont. The Central Boiler E-Classic 2300 is the only outdoor wood furnace to receive certification from Vermont.

The E-Classic 2300, which was introduced last year, shatters virtually every preconceived notion about emissions and efficiencies of wood heating. The E-Classic 2300 is so clean and efficient that it operates with combustion efficiencies greater than 98%. High combustion and delivered efficiencies together create more heat per pound of wood and extremely low emissions.

The E-Classic 2300 DF has an optional gas-fired wood ignition and dual fuel backup for the convenience of the consumer. This furnace offers a cleaner way to provide 100% of the heat for homes, outbuildings, farms and businesses. It combines the use of a totally renewable, carbon neutral fuel with the economics of wood and convenience of longer burn times. In addition, when wood is burned in an E-Classic outdoor wood furnace, it is the safest way to heat a home or building because the combustion takes place outside, eliminating the risk of an indoor fire, indoor smoke and carbon monoxide buildup in the home associated with indoor home heating appliances.

Central Boiler, with a commitment to designing environmentally responsible and industry-leading technologies, also has two outdoor wood furnace models on the EPA's list of cleaner OWHHs. The E-Classic 2300 outdoor furnace has the largest capacity, highest heat output, highest efficiency and lowest emissions per heat delivered in comparison with other units that meet the EPA's OWHH Program. Central Boiler is increasing production and shipments of the E- Classic 2300 models due to demand.

"We're proud that Central Boiler continues to lead the outdoor wood furnace industry," said Dennis Brazier, president and CEO of Central Boiler. "We produced the first two outdoor furnace models to have met the EPA's OWHH Program and we have the first outdoor furnace model to be certified by Vermont. Being the only manufacturer on the EPA's list of cleaner OWHHs to have met the 0.32 lbs/million Btu heat output emissions limit, which Vermont and other states have proposed for the future, demonstrates our technological leadership and commitment to producing environmentally responsible outdoor wood furnaces."

Other types of wood heating appliances can not offer all the advantages of an E-Classic outdoor wood furnace. An economical, environmentally responsible heating alternative, the E-Classic outdoor wood furnace uses a totally renewable resource which, when burned, results in no net increase in greenhouse gas emissions (carbon dioxide). As a "green" choice, the E-Classic is good for the environment, which is good for everyone.

Central Boiler is a leading manufacturer of quality outdoor wood, wood pellet and corn furnaces. They have been manufacturing outdoor furnaces for 23 years. Central Boiler has a sales and dealer network established throughout the United States and Canada.
