Over the two-year period, U.S. and Canadian insulation manufacturers used 4.1 billion pounds of recycled glass and 1.33 million pounds of recycled slag in the production of thermal and acoustical insulation. Recycled materials content is one measure by which architects and specifiers evaluate the sustainability profile of building products. Since the industry’s recycling program began in 1992, NAIMA members have diverted a total of 67.9 billion pounds of materials from the waste stream. The industry is committed to maximizing its use of recycled materials and continually supports efforts to do so. ### ALREADY A SUBSCRIBER?
