(CSRwire) ATLANTA - At the NAHB Green Building Conference at Atlanta, Owens Corning today announced that its line of fiber glass insulation products has been certified to contain an average of 35 percent recycled content by leading third-party certifier Scientific Certification Systems (SCS), an increase of 5 percent over its prior certification - making Owens Corning's certification level the highest in North America.

SCS approved the certification of Owens Corning's signature PINK fiber glass insulation, as well as the company's commercial fiber glass products, only after a rigorous four-step process that included a comprehensive audit of the company's claims, including visits to manufacturing facilities to see the process and interview plant personnel. This recognition by SCS assures building professionals using Owens Corning fiber glass insulation of the recycled content in order to achieve LEED certification and meet other green building guidelines, an increasingly critical measurement used in sustainable building.

"While the previous recycled content level of our fiber glass insulation products already led the industry, we seized the opportunity to further raise the bar with a move to 35 percent to demonstrate our commitment to green building and sustainability in our own manufacturing processes," said Gale Tedhams, product manager, Owens Corning Residential Insulation. "It's that commitment and our expertise that brings our leadership together with groups such as the Alliance for Sustainable Built Environments, the Department of Energy, Built Green Colorado, National Association of Home Builders and U.S. Green Building Council to achieve sustainable practices in the building industry."

The 35 percent post-industrial and post-consumer content in the company's fiber glass products is made possible by enhancements in the Owens Corning manufacturing process that utilize more waste glass from additional sources.
