Owens Corning

Owens Corning is an American company that develops and produces insulation, roofing, fiberglass composites, and related building products. As the world's largest manufacturer of fiberglass composites, it leads in three market-leading businesses: Roofing, Insulation, and Doors, serving residential and commercial sectors in North America, Europe, and beyond. Founded in 1938 through a joint venture between Corning Glass Works and Owens-Illinois, and headquartered in Toledo, Ohio, Owens Corning employs about 25,000 people across 31 countries and generates approximately $11 billion in annual sales. Notable for its iconic pink insulation, trademarked in 1986 with the Pink Panther as mascot, the company innovates in sustainable, energy-efficient solutions like recycled glass fiberglass and solar-powered facilities. A Fortune 500 member since 1955, it recently expanded via the 2024 acquisition of Masonite International for door systems, operating 30 composites, 31 insulation, and 16 roofing facilities while prioritizing environmental efforts such as shingle recycling and allergen-reducing products.
