Our Heritage


Tessenderlo factory, Belgium

In 1937, Pittsburgh Corning Corporation built their first cellular glass manufacturing facility in Port Allegany, PA USA

FOAMGLAS® cellular glass insulation is the result of more than 70 years of proven performance and continual product improvement.

The UK Office opened in 1975, and is supplied with
FOAMGLAS® from the European production plants; the newest opened in 2008 at Klášterec in the Czech Republic. 

Looking forward to the future, the construction of new production facilities and technical offices are planned to service expanding economies around the world.
