Nearly 300 million pounds of recycled glass used in insulation production last year

October 22, 2014 - The North American Insulation Manufacturers Association (NAIMA) has announced the survey results of its Canadian and U.S. members’ use of pre- and post-consumer recycled materials in insulation and acoustical products in 2013.

NAIMA Canada members used nearly 300 million pounds of recycled glass in the production of residential, commercial, industrial, and air handling thermal and acoustical insulation.

Meanwhile, U.S. manufacturers used almost 1.7 billion pounds of recycled glass in the production of residential, commercial, and industrial thermal and acoustical insulation. Manufacturers estimate they will use more than 1.7 billion pounds in 2014.

Together, U.S. and Canadian facilities used more than 588 million pounds of recycled blast furnace slag in the production of thermal and acoustical insulation. Since the industry’s recycling program began in 1992, NAIMA members’ plants have diverted more than 46.3 billion pounds of recycled materials from the waste stream.

“NAIMA members are committed to promoting sustainability by using recycled materials to produce energy-saving insulation products that improve a building’s energy efficiency and reduce environmental impact,” said Curt Rich, president and CEO of NAIMA. “Fiber glass, rock wool and slag wool insulation are some of the best choices available for insulating residential and commercial buildings as well as mechanical and industrial process systems.”


While recycled content is just one indicator of a product’s environmental impact, the survey results illustrate the significant impact that an industry can affect through the conscientious use of materials, noted the association.
