Owens Corning To Add Warehouse To Aiken, S.C., Facility

Toledo, Ohio-based glass fiber reinforcements and engineered materials producer Owens Corning will
invest $7 million to build a 175,000-square-foot warehouse adjacent to its Aiken, S.C., facility
for storing products produced at the plant. Construction of the facility is expected to be
completed by the beginning of 2014.

The expansion follows Owens Corning’s 2010 announcement that it would invest $36 million in
the Aiken plant to add a nonwoven glass fiber mat production line and 35 jobs
