Owens Corning's Gresham, Ore. Plant Becomes First LEED(R) Gold-Certified
Insulation Facility in the United States
Plant manufactures greenhouse gas-reducing FOAMULAR(R) insulation

TOLEDO, Ohio, Oct. 22 /PRNewswire-FirstCall/ -- Owens Corning (NYSE: OC), a
world leader in building materials and glass fiber reinforcements, today
announced that its Gresham, Ore. plant, which manufactures FOAMULAR® extruded
polystyrene rigid foam insulation, has received Leadership in Energy and
Environmental Design (LEED®) Gold certification for new construction from the
U.S. Green Building Council (USGBC).

Owens Corning's Gresham plant is the only LEED Gold-certified insulation
facility in the United States and one of approximately 203 industrial
facilities in the U.S. that have been awarded LEED certification. LEED is
recognized as one of the nation's pre-eminent green building certification
programs to recognize superior achievement in design, construction and
operation of green buildings.

Owens Corning's Gresham facility uses 100 percent green renewable energy and a
blowing agent that does not deplete the ozone to produce its
GREENGUARD-certified FOAMULAR® insulation, which conserves energy and reduces
greenhouse gas emissions of homes and buildings.

Created by Owens Corning, the Gresham plant's revolutionary blowing agent is
the first of its kind to be used in a Pacific Northwest facility.

By manufacturing its FOAMULAR® insulation closer to its customers, Owens
Corning's Gresham plant will prevent emissions of more than 500 tons of carbon
dioxide each year - the equivalent of more than 50,000 gallons of gasoline -
that would have been expended to transport the insulation from other
production facilities.

"We are proud that Owens Corning's Gresham facility has been recognized with
LEED Gold certification, and that the FOAMULAR® insulation produced there
helps reduce greenhouse gas emissions and conserve energy," said Frank
O'Brien-Bernini, chief sustainability officer, Owens Corning. "This honor
highlights Owens Corning's unwavering commitment to its sustainability goals,
including greening our operations, greening our products and accelerating
energy efficiency improvements in the built environment."

LEED certification is a nationally accepted benchmark for sustainable green
building practices. It promotes a comprehensive approach to sustainability by
recognizing superior performance in five key areas of environmental health:
sustainable site development, water efficiency, energy usage, materials
selection, and indoor air quality. More than 3,850 buildings in the United
States are currently LEED certified.

"Building operations are nearly 40 percent of the solution to the global
climate change challenge," said Rick Fedrizzi, president, chief executive
officer and founding chair, U.S. Green Building Council. "While climate change
is a global problem, innovative companies like Owens Corning are addressing it
through local solutions."
