Overview
Owens Corning is a United States-based manufacturer of building materials and fiberglass composites. Its principal businesses have historically centered on insulation, roofing, and glass-fiber reinforcement, with the company later expanding its building-products portfolio through acquisitions, including the 2024 purchase of Masonite International. The business traces its origins to a 1935 joint venture between Owens-Illinois and Corning Glass Works. It became a separate company in 1938 and established its headquarters in Toledo, Ohio. The company developed around the commercial potential of fiberglass. Early applications included insulation for buildings and ships, fiberglass-reinforced materials for transportation, and reinforcement products for industrial manufacturers. Owens Corning insulation was adopted as standard equipment in new United States Navy warships in 1939. During the 1940s, the company worked on fiberglass-reinforced boat and automobile bodies; fiberglass technology later became especially visible through the Chevrolet Corvette. In the 1950s, Owens Corning developed a centrifugally spun process for producing fiberglass wool, helping establish a scalable method for manufacturing thermal insulation. Insulation remains one of the company's most recognizable categories. The company is strongly associated with pink fiberglass insulation, a distinctive product color that became a major brand asset. Owens Corning began coloring its insulation pink in the 1950s and later licensed the Pink Panther as a promotional mascot. The pink color was trademarked in the 1980s and became an unusually prominent example of color-based branding in an industrial product category. Its insulation portfolio includes fiberglass and mineral-wool products as well as foam-based systems marketed for residential, commercial, and industrial applications. Roofing became another major business after the acquisition of Frye Roofing in 1977. Owens Corning subsequently developed fiberglass roofing mats and shingle systems, including the Duration line. Its roofing activities cover shingles, underlayment, ventilation, and related components used in residential construction and reroofing. The company also manufactures glass-fiber reinforcements used in transportation, infrastructure, wind-energy, electronics, consumer products, and other composite applications. Its composites operations have included joint ventures and specialized materials for industrial customers, including products used in additive manufacturing. Owens Corning became publicly traded on the New York Stock Exchange in 1952 and appeared on the Fortune 500's inaugural 1955 list. It remained on that list through the subsequent decades, although severe asbestos-related litigation led to a Chapter 11 bankruptcy filing in 2000. The company emerged from bankruptcy and returned to the New York Stock Exchange in 2006 under the ticker OC. Its modern strategy has emphasized energy efficiency, durable building envelopes, manufacturing productivity, sustainability, and broadening its building-products platform. The company operates manufacturing and commercial facilities across multiple regions. Its environmental initiatives have included the use of recycled glass in fiberglass insulation, asphalt-shingle recycling, and renewable-energy projects at manufacturing sites. In 2024, Owens Corning completed its acquisition of Masonite International, adding interior and exterior door systems to its established insulation, roofing, and composites businesses. The transaction reinforced the company's position as a diversified supplier to construction and building-products markets.
History
Owens Corning was created in 1935 as a partnership between Owens-Illinois and Corning Glass Works, two major American glass manufacturers. The venture was separated into an independent company in 1938, when its headquarters were established in Toledo, Ohio. Its early business was based on the industrial use of fiberglass, particularly thermal insulation and reinforcement materials. In 1939, the United States Navy adopted Owens Corning insulation as a standard material for new warship construction. During the 1940s, Owens Corning extended fiberglass into transportation and marine applications. It produced a prototype fiberglass-reinforced boat hull in 1944 and worked with an automaker on an early fiberglass-reinforced plastic automobile body in 1945. General Motors later used fiberglass body technology in the Chevrolet Corvette. In 1954, the company developed a centrifugal-spinning process for fiberglass wool, a production method that became important to the insulation industry. It introduced Perma-Ply roofing material in 1955 and developed all-fiber fiberglass wool the following year. The company's pink insulation emerged as a distinctive consumer and trade brand during the 1950s. Red dye was added to fiberglass wool, producing the color now associated with Owens Corning. Although the company initially considered removing the color, customer response encouraged it to restore the pink appearance. Owens Corning subsequently licensed the Pink Panther for advertising and used the character to connect a highly visible mascot with an otherwise technical construction product. The company secured trademark protection for the color in the 1980s. Owens Corning became publicly listed on the New York Stock Exchange in 1952 and appeared on the first Fortune 500 list in 1955. It established research and testing facilities near Granville, Ohio, and expanded internationally through Owens-Corning Fiberglas Europe in 1965 and an Asia-Pacific division in 1993. In the 1960s it also explored fiberglass-reinforced automobile tires through a partnership with Armstrong Rubber. Sales passed $1 billion in the 1970s, while the company broadened its building-materials portfolio through the acquisition of Frye Roofing in 1977. That transaction helped establish fiberglass roofing mat and shingles as a major business. The company's history was heavily affected by asbestos litigation. In 1978, shipyard workers filed a class-action lawsuit alleging that Owens Corning and other manufacturers had known about asbestos-containing products. The company was later named in hundreds of thousands of asbestos claims. It settled many claims before filing for Chapter 11 bankruptcy in 2000. The bankruptcy process led to a restructuring of the business and the removal of its shares from the New York Stock Exchange in 2002. Owens Corning returned to the exchange in 2006 under the symbol OC. Expansion continued through acquisitions and partnerships. The company acquired aerospace and strategic-metals operations in 1985, UC Industries and its FOAMULAR polystyrene insulation business in 1994, and Fibreboard Corporation in 1997. It formed OCV Reinforcements with Saint-Gobain in 2007 and collaborated with DuPont on a racetrack safety barrier in 2011. Later initiatives included recycled-glass sourcing, shingle recycling, solar power at manufacturing sites, mineral-wool expansion, and the XStrand family of materials for 3D-printing composites. In 2024, Owens Corning completed the acquisition of Masonite International. The transaction added interior and exterior doors to a portfolio already organized around insulation, roofing, and composites. The company therefore entered its current period as a diversified building-products manufacturer, combining branded products sold through construction channels with engineered materials supplied to industrial customers.
