CertainTeed Corp. announced it has secured third-party GreenCircle certification for 20 of its ceilings products. In addition, the company also unveiled new, more environmentally friendly packaging for its ceilings products.

GreenCircle certification consists of a comprehensive audit that verifies the manufacturing process and recycled material use, as well as a thorough review of the specifications and actual recipes for the products produced.

Sustainable Solutions Inc., an independent sustainability consulting firm, conducted the certification process through a rigorous analysis of the recycled content of CertainTeed Ceilings products-such as Adagio, Baroque and Symphony-that are manufactured at the company’s plants in L’Anse, Mich., and Plymouth, Wis. The certified recycled content of the products reviewed ranges from 3 to 72 percent.

“This valuable third-party certification is one of many aspects of sustainability we’re tackling as we embrace the broad perspective of our environmental impact and the life-cycle of products,” said Cedric Woindrich, vice president and general manager of CertainTeed Ceilings.

In addition to GreenCircle certification, CertainTeed Ceilings has embraced more environmentally friendly packaging for its products. With the help of Green Bay Packaging Inc., CertainTeed has converted its packaging for ceiling panels to an unbleached paperboard with an increased recycled content of up to 98 percent. According to Green Bay Packaging, the switch will preserve an estimated 3,430 trees annually.

“CertainTeed Ceilings’ dedication to this process is demonstrative of the company’s overarching commitment to reducing their impact on the environment,” said Tad Radzinski, president of Sustainable Solutions.
