The roots of Pittsburgh Corning go way back to the 1930's in the United States. Two American companies, Pittsburgh Plate Glass Company and Corning Glass Works, both leading companies in the American glass industry, founded Corning Corporation in 1937. During the following decades, the industrial group acquired an immense know-how and an extraordinary expertise in the industrial usage of glass as an insulation.

 
In 1962, a business was founded in Europe, and a production unit was constructed on the Belgium company site in Tessenderlo.  

In 2000 Pittsburgh Corning Czech Republic was founded and the construction of the production plant in Klášterec nad Ohří began. This production plant was designed  with the latest available technologies in the foam glass industry and became operational in 2008.  Nowadays, FOAMGLAS® products are manufactured in the production facilities of Tessenderlo (Belgium), Klášterec (Czech Republic), Yantai (China), Sedalia (USA) and Fresno (USA).
