CertainTeed Corp. announced that 20 of its products now have “green-approved” status from the National Association of Home Builders’ research center.

NAHB gives the status to environmentally friendly products that align with the organization’s National Green Building Standard. Through the program, points are awarded based on factors that contribute to the sustainability of a product, including recycled content, manufacturing plant certification, and the use of durable, termite-resistant materials.

“Receiving green-approved status from the NAHB validates our commitment to being the industry leader in the development of sustainable building products and the environmentally friendly operation of our manufacturing facilities,” said Aman Desouza, director of innovation and sustainability for CertainTeed Corp. “We want to walk lock-step with builders, contractors, architects and specifiers to ensure we help them meet today’s green building requirements.”

The certification was given to 20 CertainTeed products, including duct-wrap insulation.
