2021 Owens Corning Sustainability Report | Expanding Our Product Handprint | Product Innovation & Stewardship | 98 Photos: Top: Windstrand ® composite material. Bottom: TruDefinition ® Duration ® COOL Plus Shingles in Midnight. Composites Innovations WindStrand ® This innovative material allows wind blade manufacturers to use 30% fewer layers of material in the blade molds, while delivering the same quality and performance as standard fabrics. This in turn represents a 50% savings in labor and production time for the blades. In March 2021, we introduced WindStrand ® 4000, as well as Ultrablade ® 2 and Ultraspar™ 2, three high-performance materials that help wind blade manufacturers develop longer, stiffer, stronger blades. This in turn helps make wind energy more cost-effective. In 2021, Owens Corning introduced ArmaStrand™ Type 30 ® Single-End Roving product into the Russian market. This product is specifically designed to provide customers with productivity savings while increasing the service life of rebar. Using corrosion-resistant Advantex ® glass fiber, ArmaStrand™ has the flexibility to be used in a variety of rebar manufacturing processes and maximizes the mechanical properties of rebar systems with increased fiber content and higher bar modulus to meet new industry demands. Roofing Innovations Duration FLEX ® The only modified polymer asphalt shingle with SureNail ® technology, with nearly 1.5x the nail-pull strength and 10% better strength than standard shingles, Duration FLEX ® also features improved granular adhesion and meets the highest impact resistance rating. After a successful launch in the U.S., Owens Corning developed a version specifically for the Canadian market. In 2021 Owens Corning continued to promote Duration FLEX ® in Canada to allow customers to access a version of Duration FLEX ® that meets CSA 123.5 standards as well as UL 2218 Class 4 impact resistance. The Cool Roof Collection Using a highly reflective granule technology that reflects the sun’s rays, Cool Roof shingles help reduce energy use by keeping roofs cooler and reducing air conditioning energy levels. Owens Corning offers a wide array of shingle choices that meet or exceed an aged SRI of 20 — the current aged Solar Reflectance Index minimum required for the Green Building Standards Code of Los Angeles County and Los Angeles City Cool Roofs Ordinance. In 2021, Owens Corning launched Duration ® COOL Plus Midnight color providing a new dark color offering in this energy saving line. Trumbull ® Asphalt Over the last six years, our Trumbull ® asphalt has made significant strides to reduce the number of oxidized products we produce for external asphalt markets. In 2015, 8% of our products were non-oxidized. Today, approximately 50% of the products we produce for the external asphalt business are non-oxidized, requiring less energy, lower temperatures, and fewer emissions. This has resulted in a 3% improvement in material efficiency across the 12 asphalt plants in the network. Recyclable Protective Packaging The European Union’s policy requires all plastic packaging in the EU market to be recyclable or reusable by 2030 to support the transition to a circular economy. Owens Corning is partnering with key players in lumber and steel to develop solutions through our expertise in polymer streams, with a goal of achieving these solutions by 2025.
