Made from a block of cellular glass, FOAMGLAS Perinsul SIB is made to eliminate thermal bridging beneath exterior masonry veneer walls. This thermal bridge near the foundation has historically been a difficult spot to thermally mitigate as the insulating material needs to meet both structural load and thermal performance requirements. Consequently, cellular glass, with its compressive strength, dimensional stability, and protection against thermal energy loss, not to mention water impermeability, is a great solution for meeting new ASHRAE thermal bridging requirements.
