FOAMGLAS® HLB 2400 insulation (ASTM)

Description

FOAMGLAS® HLB 2400 Insulation is a high-load-bearing cellular glass insulation engineered for extreme industrial applications. With unparalleled compressive strength, thermal performance, and dimensional stability, this insulation is ideal for cold and cryogenic tank bases, high-temperature applications, and load-bearing pipe supports. It is noncombustible, nonabsorbent, and chemically resistant, providing long-term protection in challenging environments.
