Careers at Owens Corning


Owens Corning manufactures a range of composite and building materials, designed to provide high-quality solutions to customers operating across multiple industries.

Business segments

Owens Corning organises its activities into three reportable business segments:

  • Composites, including the Company’s Reinforcements and Downstream units, which respectively manufacture and sell glass reinforcements – in the form of fiber – and glass fiber products – in the form of fabrics, non-wovens and other specialised products;
  • Insulation, which manufactures and sells insulation products that are designed to conserve energy and provide improved acoustical performance – including thermal and acoustical batts, loosefill insulation, foam sheathing, and accessories – and manufactures and sells glass fiber pipe insulation, energy efficient flexible duct media, bonded and granulated mineral fiber insulation; and
  • Roofing, which manufactures and sells a range of roofing products, including laminate and strip asphalt roofing shingles, oxidised asphalt, and roofing accessories.


Owens Corning has its roots in two glassworks companies, Owens-Illinois and Corning Glass Works – which merged in 1935. The fiberglass operations of the two businesses were spun off in 1938 as a separate corporate entity under the name Owens Corning Fiberglass Corporation.

Owens Corning developed a lightweight, nonflammable fiberglass insulation product called Navy Board, which served as the Company’s principal product throughout World War II. The Company went on to pioneer the use of fiberglass in boat and automobile manufacturing, and diversified its product portfolio to include insulation – taking advantage of rising energy costs – as well as fiberglass reinforced shingles.

Today Owens Corning is among the largest manufacturers of composite and building materials in the world, providing an extensive range of composites, insulation products, and roofing materials to end users across multiple business sectors. The Company serves an international customer base, spanning markets across the Americas, Asia Pacific, and Europe.

Owens Corning is ranked 480th on the Fortune 500 list and 1,391st on the Forbes Global 2000 list. The Company trades a portion of its shares on the New York Stock Exchange and has a current market capitalisation of $6.00 billion.
