Canadian manufacturers of insulation used nearly 300 million pounds of recycled glass in their products last year, according to a survey by the North American Insulation Manufacturers Association (NAIMA).

“We are proud and excited that our 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 its environmental footprint,” says the executive director of NAIMA Canada, Jay Nordenstrom.

In Canada, the majority of glass comes from post-consumer products, including plate and bottle glass. Recycled glass was used in the production of residential, commercial, industrial and air-handling thermal and acoustical insulation.

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