Our Heritage

Company Heritage


As a world-class manufacturer of sustainable, high-performance glass insulating products for the building, energy, and industrial markets, Pittsburgh Corning has been on the forefront of designing products that stand the test of time.


Pittsburgh Corning Corporation had a promising start in 1937, with one innovative product, architectural glass block, and the support of two renowned companies – Pittsburgh Plate Glass Company and Corning Glass Works. When the company was founded, its sole purpose was to produce and sell glass block products to the building and construction market.  In 1947, FOAMGLAS® insulation was first manufactured for industrial use.


Over the past 79 years, Pittsburgh Corning has evolved into a leading global manufacturer of innovative and technically advanced FOAMGLAS® insulation products for the industrial, commercial and building markets. Its sustainable products conserve energy, protect the environment, and have improved the lives of millions of people in virtually every country in the world.


With its FOAMGLAS® cellular glass insulation, Pittsburgh Corning has earned a reputation for creating high-performance, premium quality, environmentally sustainable insulation systems. The company’s unique insulation products provide superior protection and energy conservation in a wide range of applications surrounding the commercial building envelope, on HVAC systems, cladding industrial process piping and supporting oil and gas storage tanks.
