CertainTeed has answers on recycled content

CertainTeed Insulation published a white paper titled “Understanding Recycled Content Reporting,” as a response to a recent ruling by the U.S. Green Building Council (USGBC).

A new LEED Interpretation Ruling (LIR), released Oct. 1, ruled manufacturers can no longer use an average of multiple places of manufacture when reporting recycled-content claims, according to the report.

The Valley Forge, Pa.-based manufacturer said the purpose of the white paper is to help architects, specifiers and builders navigate the new process for recycled content claims. A number of manufacturers aggregate data or use averages across multiple plants, which is no longer acceptable for LEED documentation, according to the report.
