Pittsburgh Corning Corporation
Workers Exposed to Asbestos
The company was formed in 1937 after a merger took place between Corning Glass Works and Pittsburgh Plate Glass Company. It was known initially as a manufacturer of commercial and residential windows and glass block shower systems. In 1962, Pittsburgh Corning expanded its product line to pipe and block insulation by acquiring the Unibestos product line from UNARCO Industries. For 10 years, starting from 1962 until 1972, Pittsburgh Corning manufactured and sold pipe insulation and covering under the brand Unibestos. Its products were mainly used in the steam fitting, pipe fitting and plumbing industries.
