Owens Corning Launches Shingle Recycling Program

First manufacturer to simplify shingle recycling for contractors

TOLEDO, Ohio, Nov. 3 /PRNewswire-FirstCall/ -- Owens Corning (NYSE: OC) today
announced through its Roofing business that it will provide a new program that
simplifies recycling asphalt shingles for its Preferred Roofing Contractors.
The company is the first roofing manufacturer to connect contractors with
convenient recycling facilities through a national strategic alliance.

Based on a pilot conducted in Indiana, Owens Corning will roll out the program
nationally, starting in the Midwest. As part of the program, contractors
pledge to recycle their shingle tear-offs. In addition to keeping shingle
waste out of landfills, contractors benefit by promoting sustainable business
practices to homeowners.

"While the technology exists to recycle asphalt shingles, we are making it
efficient and cost-effective for our contractors," said Sheree Bargabos,
president of Owens Corning Roofing and Asphalt, LLC. "This program makes
recycling easy, and provides our contractor network with an opportunity to
clearly differentiate themselves by providing a complete roofing system
including a sustainable end-of-life recycling option for old shingles."

Owens Corning is working with Heritage Environmental Services, the largest
privately-held environmental services company in the United States. Heritage
will provide dedicated, convenient drop-off centers that will recycle and
process shingle tear-offs.

"Millions of tons of asphalt roofing shingles are sent to landfills every
year, wasting valuable resources such as asphalt and aggregate," said Bill
McDaniel, president and chief executive officer, Heritage Environmental
Services LLC. "With the combined efforts of Heritage and Owens Corning,
material that would have been wasted will now be reused and made into roads."

Recycling glass-based asphalt shingles is a cost-effective alternative to
producing new asphalt and helps preserve resources. Last year the Asphalt
Institute estimated that the asphalt from recycled shingles has a potential
value of more than $1 billion, which is variable upon the price of asphalt.

"At Owens Corning, we are constantly seeking solutions that carry economic,
environmental and social benefits. This new program is the perfect example of
carefully considered product life-cycle management, from conception of design
and manufacture to durable service and end-of-life recycling," said Owens
Corning Chief Sustainability Officer, Frank O'Brien-Bernini. "We are proud to
be the first roofing manufacturer to help create an infrastructure to increase
shingle recycling and material reuse across the country."
