Owens Corning (OC)

The roofing business is the company’s largest revenue contributor. It produces asphalt shingles, roofing components, oxidized asphalt materials, and related products used primarily in residential homes. Owens Corning also supplies glass mat and specialty veil materials that support roofing and other construction applications. The strength of this segment is tied closely to reroofing cycles, storm-related repair activity, housing turnover, and broader conditions in the North American construction market.

In insulation, Owens Corning manufactures thermal and acoustical products, including fiberglass batts, loose-fill insulation, spray foam, and other materials designed to improve energy efficiency, comfort, and sound control. These products are used in homes, commercial buildings, industrial settings, and specialty applications. Its doors operations broaden the company’s portfolio into entry and interior door systems, adding another category linked to home improvement and building activity.

Owens Corning generates most of its revenue in the United States, while also serving customers in Europe, Asia-Pacific, and other international markets. The company is distinctive for combining well-known consumer-facing brands with large-scale manufacturing, materials science expertise, and a product mix that spans essential construction categories.
