North American Insulation Manufacturers Association members in the U.S. and Canada logged 2.66 billion pounds of recycled glass and nearly 700 million pounds of recycled slag in their 2022 output of fiber glass and rock or wool thermal and acoustical products for residential, commercial and industrial applications. Since the industry’s recycling program began in 1992, NAIMA member plants have diverted 100 billion-plus pounds from the waste stream.

“Our industry continues to demonstrate its commitment to using recycled materials,” says NAIMA CEO Curt Rich. “With increased focus on whole building decarbonization, insulation products will be a critical component of that activity. Sourcing recycled materials is one way we can decrease our environmental impact while producing essential insulation materials that ultimately lower building emissions.”  —
