Industrial Processing

Since 1937, Pittsburgh Corning has been the leader in cellular glass insulation and material technology. As a result, FOAMGLAS® Insulation has been providing long-term thermal performance on systems and equipment around the world. Our booth video takes you through the manufacturing and fabrication processes. The highlighted text in this overview links to specific web pages for additional information regarding FOAMGLAS® Insulation application capabilities.
FOAMGLAS® Insulation is a lightweight, rigid mechanical insulation material composed of millions of sealed glass cells, each an insulating space. It is used on a wide variety of industrial and commercial applications with outstanding long-term results. Its all-glass closed-cell structure provides physical properties ideal for piping and equipment above and below ground, indoors or out, at operating temperatures from -450◦F to +900◦F.
FOAMGLAS® Insulation is made from sand, recycled glass and other abundant natural materials. The materials are combined then heated to produce molten glass. The glass is cooled then crushed into a powder and placed in individual molds. The molds pass through a cellulating oven where the glass rises into a block and is slowly cooled in an annealing furnace.
FOAMGLAS® Insulation blocks are ground flat on all surfaces then packaged and shipped. The material can then be fabricated, by authorized contractors and fabricators, in a wide range of shapes, thicknesses and sizes to meet virtually all industrial and commercial insulation requirements.
FOAMGLAS® Insulation has a 0.00 permeability making it resistant to water in liquid or vapor form, has long-term constant thermal performance and is non-corrosive. The material does not contain HCFC, CFC or toxic blowing agents and does not contain crystalline silica. FOAMGLAS® Insulation is non-combustible and will not wick flammable liquids. It has superior compressive strength and is effective in a wide temperature range.
FOAMGLAS® Insulation also has long-term dimensional stability as glass does not shrink or swell. It remains stable; therefore there is no warping or buckling. This provides minimum stress to the insulation system, joints and coverings at extreme temperature changes.
