Owens Corning (NYSE: OC) is a building products manufacturing company that produces and sells insulation, roofing, and composites materials for residential and commercial construction markets.

Founded in 1938 and headquartered in Toledo, Ohio, Owens Corning recorded net sales of $10.1 billion in FY2025 and employs approximately 25,000 people across 31 countries.
