Fire-Resistant Foam Glass Insulation for Building & Industrial Applications
Leadsun Foam Glass (Cellular Glass) is an advanced, closed-cell insulation material produced from an all-glass composition. It delivers outstanding thermal insulation, complete waterproof integrity, non-combustible fire resistance, and long-term chemical stability. Capable of operating continuously from cryogenic (-268°C) to high-temperature (482°C) extremes, it is engineered for demanding applications—whether outdoors, underground, submerged, or in chemically aggressive environments. The product is offered as boards, blocks, and pre-formed shells for insulating pipes, vessels, and ducts.
