Cellular Glass (FOAMGLAS)

Cellular glass insulation is a light-weight, rigid material made of sealed glass cells, each of which is an insulating entity. It achieves excellent fire without the use of flame retardants.

Common Applications

While a less-efficient as a thermal insulator than more commonly-used foam insulators, cellular glass insulation features properties particularly beneficial for long term applications, including zero water vapor permeability, and zero combustibility. Long-lasting outdoor installations that require little maintenance are especially well suited:

  • Hot oil and hot asphalt storage tanks
  • Oil and chemical processing systems
  • Commercial piping and ductwork
