Owens Corning

What does Owens Corning own?
Owens Corning owns three business segments, Roofing, Insulation, and Doors, plus product brands including PINK Fiberglas, Duration shingles, Foamular, Thermafiber, Paroc, Masonite, and Deckorators. It sold its glass reinforcements business in 2025.

Is Owens Corning publicly traded?
Yes. It trades on the New York Stock Exchange under ticker OC and is a member of the S&P 500. Shares have been public since 1952.

When was Owens Corning founded?
The company was formed in 1938 in Toledo, Ohio, as Owens-Corning Fiberglas Corporation, a joint venture between Owens-Illinois and Corning Glass Works to commercialize glass fiber.

Who owns Owens Corning?
Public shareholders own it. Institutional investors hold most shares and no founding family or partner company retains control. Brian Chambers is chairman and CEO.

What is Owens Corning's market position?
It is one of the two largest asphalt shingle producers in North America and a leading fiberglass insulation manufacturer. Roofing produces roughly a third of EBITDA margin even in weak markets.

Did Owens Corning go bankrupt?
Yes. Asbestos injury claims from a legacy pipe insulation product forced the company into Chapter 11 in 2000. It emerged in 2006 after funding an approximately $7 billion claimant trust and has operated profitably since.

Owens Corning was formed in 1938 as a joint venture between Owens-Illinois and Corning Glass Works to commercialize glass fiber, a material Corning had recently learned to manufacture economically. The new company, Owens-Corning Fiberglas Corporation, pioneered fiberglass insulation for construction and glass-reinforced materials for industry. It became a fully public company in 1952.

Through the following decades, the company expanded Fiberglas insulation into a household name. Its 1980s licensing of the Pink Panther cartoon character to sell PINK insulation became one of the longest-running mascot arrangements in advertising. The company shortened its name to Owens Corning in 1997.

The modern era includes both crisis and reinvention. A surge of asbestos injury lawsuits tied to a pipe insulation product sold decades earlier forced the company into Chapter 11 bankruptcy in 2000; it emerged in 2006 after funding an approximately $7 billion trust for asbestos claimants. Roofing, expanded through a series of plant investments and regional acquisitions over the following two decades, became the company's profit engine.

Recent moves reshaped the portfolio toward branded building products. In May 2024, Owens Corning acquired door manufacturer Masonite International for approximately $3.9 billion, creating the Doors segment. It simultaneously moved to exit commodities, selling its glass reinforcements business to Praana Group in 2025 and divesting its Chinese building materials unit.

FY2025 delivered $10.1 billion in continuing-operations sales and adjusted diluted EPS of $12.05, though housing market weakness and the Doors impairments dragged reported results. In Q3 2026, reported November 4, 2026, sales fell 7% to $2.5 billion as a second straight year of low storm activity depressed roofing volume.

Owens Corning has one of the longer sustainability track records in building materials. It publishes annual sustainability reports covering energy, emissions, recycled content, and safety, and has committed to science-based emissions reduction targets. Its insulation products are themselves an energy-saving product category, which the company counts toward avoided emissions.

Manufacturing improvements include increased use of recycled glass in fiberglass production and take-back programs for shingle recycling in some markets. The company has appeared on the Dow Jones Sustainability Index and related ESG rankings for multiple years.

The defining historical controversy is asbestos. Pipe insulation sold by the company decades ago produced a wave of injury claims that drove Owens Corning into Chapter 11 bankruptcy in 2000. The company emerged in 2006 after establishing a trust of approximately $7 billion to compensate claimants, one of the largest asbestos resolutions in US corporate history.

Current scrutiny is less severe. The two Doors impairments have drawn analyst questions about acquisition discipline, and environmental groups monitor emissions from fiberglass and asphalt production. The company also faces the standard OSHA and EPA compliance regime of a heavy manufacturer, with no material enforcement actions disclosed in recent filings.
