2021 Owens Corning Sustainability Report | Expanding Our Product Handprint | Product Innovation & Stewardship | 107 Made with Renewable Electricity A growing number of Owens Corning ® products, including some of our high-density insulation products and shingles, are certified as made with 100% renewable electricity and are part of a reduced embodied-carbon portfolio. These products were certified in accordance with SCS Global Services’ certification protocol. The certifications are made possible by power purchase agreements Owens Corning signed in 2015, which enabled new wind capacity in Texas and Oklahoma. Both wind farms came online in late 2016 and have the potential to generate 1.1 million megawatt hours of electricity per year. Owens Corning obtains and retires the energy attribute credits (EACs) generated by these wind farms, enabling us to receive third-party renewable electricity certification. We currently have 15 products that are certified: ■ EcoTouch ® Metal Building Insulation. ■ EcoTouch ® Flexible Duct Media Insulation. ■ Pink ® Next Gen™ Fiberglas™ Insulation. ■ Unbonded Loosefill Insulation. ■ Thermafiber ® Insulation. ■ Thermafiber ® Formaldehyde-Free Insulation. ■ QuietR ® Duct Board Insulation. ■ QuietR ® Spiral Duct Liner. ■ FOAMULAR ® NGX™ XPS Insulation. ■ Fiberglas™ 700 Series Insulation Board. ■ Fiberglas™ Insul-Quick ® Insulation. ■ Ceiling Board. ■ Duration ® , Oakridge ® , and Supreme ® 3-Tab shingles from our facility in California. These certified products, which make up 26% of our total revenues, alert commercial architects, specifiers, builders, and homeowners to lower-carbon product options as they seek to build greener structures. They also help architects design buildings with reduced life cycle impacts, in keeping with the recognized goals of the Architecture 2030 Challenge and U.S. Green Building Council’s LEED ® certification. Material Health In accordance with our environmental, health, safety, and product stewardship policy, we provide information about all our products, their performance, and safe use. Product content information can be found on product labels, EPDs, HPDs, and other transparency documents such as Declare labels. Content and disposal information is included on safety data sheets or safe use instruction sheets. Health Product Declarations ® (HPDs) and Declare Labels HPDs are an effective means of reporting the chemical makeup of a product and disclosing potential hazard concerns. The reporting follows a set of stringent guidelines set by the Health Product Declaration Collaborative ® (HPDC). Potential hazards are screened based on the GreenScreen for Safer Chemicals and additional lists from other agencies. HPDs enable architects, builders, and specifiers to evaluate and specify products with a comprehensive understanding of the product composition and potential hazards. Owens Corning’s HPDs are available for download from the HPD Public Repository. In 2021, we worked to ensure that all certifications were current. Owens Corning also has Living Building Challenge- Compliant Declare labels from the International Living Future Institute™ for unbonded loosefill fiberglass insulation, unfaced and kraft-faced PINK Next Gen™ Fiberglas™ (formerly EcoTouch ® ) insulation, faced and unfaced Thermafiber ® formaldehyde-free mineral wool insulation, and Thermafiber ® Rainbarrier ® continuous mineral wool insulation. This certification demonstrates these products are fully compliant with the Living Building Challenge and allows them to be specified for LBC projects.
