Owens Corning

At December 31, 2024, the Company had an integrated business model with four reportable segments: Roofing, Insulation, Doors and Composites, which accounted for approximately 36%, 32%, 13% and 19% of our total reportable segment net sales, respectively, in 2024.

Roofing

Our primary products in the Roofing segment are laminate and strip asphalt roofing shingles. Other products include roofing components and oxidized asphalt. We have been able to service the growing demand for longer lasting, aesthetically attractive laminate products with efficient capital investment.

We sell shingles and roofing components primarily through distributors, home centers and lumberyards in the United States. Oxidized asphalt is a significant input used in the production of our asphalt roofing shingles. We are vertically integrated and have manufacturing facilities that process asphalt for use in our roofing shingles manufacturing process. In addition, we sell processed asphalt to other shingle manufacturers, to roofing contractors for built-up roofing asphalt systems and to manufacturers in a variety of other industries, including automotive, chemical, rubber and construction. Asphalt input costs and third-party asphalt sales prices are correlated to crude oil prices.

Demand for products in our Roofing segment is generally driven by both residential repair and remodeling activity and by new residential construction. Roofing damage from major storms can significantly increase demand in this segment. As a result, sales in this segment do not always follow seasonal home improvement, remodeling and new construction industry patterns as closely as our Insulation segment.

Our Roofing segment competes primarily with asphalt shingle manufacturers in the United States. According to various industry reports and Company estimates, Owens Corning’s Roofing segment is the second largest producer of asphalt roofing shingles in the United States. Principal methods of competition include innovation and product design, proximity to customers, quality and price.

Our manufacturing operations are generally continuous in nature, and we warehouse much of our production prior to sale since we operate with relatively short delivery cycles. One of the raw materials important to this segment is sourced from a sole supplier. We have a long-term supply contract for this material, and have no reason to believe that any availability issues will exist. If this supply was to become unavailable, our production could be interrupted until such time as the supplies again became available or the Company reformulated its products. Additionally, the supply of asphalt, another significant raw material in this segment, has been constricted at times. Although this has not caused a significant interruption of our production in the past, prolonged asphalt shortages would restrict our ability to produce products in this segment.

Insulation

Our insulating products provide a variety of benefits such as energy conservation, thermal functionality, improved acoustical performance and convenience of installation and use. Our Insulation segment includes a diverse portfolio of high, mid and low-temperature products with a geographic mix of United States, Canada, Europe, Asia-Pacific and Latin America, a market mix of residential, commercial, industrial and other markets, and a channel mix of retail, contractor and distribution.

Our products in the North American residential market include thermal and acoustical batts, loosefill insulation, spray foam, foam sheathing and accessories, and are sold under well-recognized brand names and trademarks, such as Owens Corning PINK® Next Gen™ FIBERGLAS™ Insulation. Our products in the commercial and industrial markets include glass fiber pipe insulation, energy efficient flexible duct media, bonded and granulated stone wool insulation, cellular glass insulation and foam insulation used in above- and below-grade construction applications, and are sold under well-recognized brand names and trademarks, such as FOAMULAR®, FOAMGLAS® and Paroc®. We sell our insulation products primarily to insulation installers, home centers, lumberyards, retailers and distributors in the United States, Canada, Europe, Asia-Pacific and Latin America.

Demand for Owens Corning’s insulating products is driven by North American new residential construction, repair and remodeling activity, commercial and industrial construction activity in the United States, Canada, Europe, Asia-Pacific and Latin America, and increasingly stringent building codes and the growing need for energy efficiency. Demand in the segment typically follows seasonal home improvement, remodeling and renovation and residential, commercial and industrial construction industry patterns. Demand for residential insulation in North America typically follows housing starts on a three-month lagged basis, although the new residential construction cycle can elongate due to labor availability and other factors beyond our control. The peak season for home construction and remodeling in our geographic markets generally corresponds with the second and third calendar quarters. Demand for commercial and industrial applications is more heavily tied to industrial production growth, commercial construction activity and overall economic conditions in the global markets we serve.

Our Insulation segment competes primarily with fiberglass insulation manufacturers in the United States, with an international presence in Canada, Europe, Asia-Pacific and Latin America. According to industry reports and Company estimates, Owens Corning is North America’s largest producer of residential, commercial and industrial fiberglass insulation. Principal methods of competition include innovation and product design, service, location, quality, price and compatibility of systems solutions.

Doors

Our primary products in the Doors segment are residential interior and exterior doors made of wood, glass, fiberglass and metal, and door components such as frames, sills, weather-stripping, hinges and locks. Other products in this segment are aluminum-framed glass doors and window solutions for luxury homes. Our doors are available in good, better and best options and provide a range of benefits including energy efficiency, comfort, privacy and security and curb appeal.

We serve the needs of the residential repair, remodel and new construction markets in the United States, Canada and the United Kingdom. Doors are sold through wholesale and retail distribution channels. In the wholesale channel, we sell through distribution partners to homebuilders, contractors, lumberyards, dealers and building products retailers. One-step distributors sell doors directly to homebuilders and remodeling contractors, while two-step distributors purchase doors in bulk quantities for local door dealers who often perform additional value-added services such as pre-hanging or pre-finishing the door before installation. The retail channel serves consumers and contractors through retail home centers, both in-store and online.

Demand for products in Owens Corning’s Doors segment is driven by new construction and overall economic conditions in the markets we serve. The Doors segment’s vertically integrated operations extend from raw material to final assembly and fabrication. According to various industry reports and Company estimates, Owens Corning is one of North America’s largest producers of interior and exterior doors. Primary methods of competition include service, quality, innovation, and product customization.

Composites

Owens Corning glass fiber materials can be found in over 40,000 end-use applications primarily within three markets: building and construction, renewable energy and infrastructure. Such end-use applications include building structures, roofing shingles, tubs and showers, pools, decking, flooring, marine, auto, pipes and tanks, poles, electrical equipment and wind-energy turbine blades. Our products are manufactured and sold worldwide. We primarily sell our products directly to parts molders and fabricators. Within the building and construction market, our Composites segment sells glass fiber and/or glass mat directly to a small number of major shingle manufacturers, including our own Roofing segment.

Our Composites segment includes vertically integrated material solutions. The Company manufactures, fabricates and sells glass reinforcements in the form of fiber and mats. Glass reinforcement materials are also used downstream by the Composites segment to manufacture and sell glass fiber products in the form of non-wovens, fabrics and composite lumber.

Demand for composites is driven by general global economic activity and, more specifically, by the increasing replacement of traditional materials, such as aluminum, wood, paper and steel with composites that offer lighter weight, improved strength, lack of conductivity and corrosion resistance.

We compete with glass fiber and building material manufacturers worldwide. According to various industry reports and Company estimates, our Composites segment is a world leader in the production of glass fiber reinforcement and other building materials. Primary methods of competition include innovation, quality, customer service, global geographic reach, sustainability and product customization.
