Huntingdon Fiberglass History

Our manufacturing facility in Huntingdon, Pennsylvania, has produced fiberglass reinforcements for more than 70 years. Originally built in 1917 as a silk mill, the plant switched to fiberglass production in the 1940s when Owens Corning and the U.S. government partnered to manufacture materials for World War II.

After the war, Owens Corning added the factory to its composites business, expanding production to continuous filament mat (CFM) in 1962. Owens Corning, and later its AGY joint venture with Porcher Industries of France, operated the Huntingdon manufacturing facility until Huntingdon Fiberglass Products took ownership in 2013.

Since the merger in 2016, Huntingdon Fiberglass Products (now Superior Huntingdon Composites, LLC) proudly continues to produce high-quality CFM, conductive roving and wound products. These innovative products are manufactured in central Pennsylvania for customers all around the world.

E-glass and Continuous Filament Mat (CFM) were developed and perfected in Huntingdon.

1950s

The Owens Corning Huntingdon facility experienced continued expansion and development.

1946

Owens Corning purchased the Huntingdon facility from the government.  By this time, fiberglass had become Huntingdon’s largest industry in terms of personnel, payroll, and invested capital. It was believed that fiberglass yarns could meet a variety of new and unexplored civilian uses.

1943

A joint venture took place between the War Department (DoD) and Owens Corning to supply fiberglass to the war effort.  Huntingdon Throwing Company was selected as a place to expand production facilities and was purchased for $175,000.  Construction took place in 1943 and the venture operated under the title of Defense Plant Corporation.

1940

Due to financial difficulties and the prospect of bankruptcy, employees and stockholders bought out Susquehanna Silk Mills and renamed it the Huntingdon Throwing Company.

1925

After some remodeling and adding of equipment, the buildings adopted the name of Huntingdon Specialty Company. (Over the next ten years, synthetic yarns, cotton, and wool largely replaced the silk throwing process.)

1917

Susquehanna Silk Mill built a silk throwing mill in Huntingdon.
