Foamglas® insulation is a lightweight, rigid insulation composed of millions of completely sealed glass cells. Each cell serves as an insulating agent. Foamglas® is widely used in the cryogenic and hotline pipe supports and is fabricated in various ranges of shapes, thicknesses, and sizes to meet the particular requirements of an application.
One unique advantage that Foamglas® has is its very low moisture absorption. Since Foamglas® insulation is full of closed glass cells, it resists moisture in both liquid and vapor form. This guarantees the long-term performance of the insulation. Foamglas® insulation’s resistance to moisture ensures that properly installed, it retains its original thermal efficiency.
The major advantages and applications of Foamglas® insulation are listed below. For details about the physical and mechanical properties of the Foamglas® material, please refer to the table.
