Easy Cutting Rigid Cellular Glass Insulation Board No Moisture Permeability
As an advanced thermal insulation material, cellular glass is widely used in petroleum industry, chemical industry, underground engineering, shipbuilding and defense works. It can be used in cryogenic insulation systems in pharmaceuticals, hydrocarbon processing, low temperature piping, equipment and storage tanks, cold storage buildings, steel liquid oxygen/nitrogen storage tanks and pipelines, as well as exterior wall insulation, roofing, and basement applications.
Cellular glass is an inorganic rigid insulation material that is non-toxic, environmentally friendly, and suitable for both cryogenic and high-temperature environments. It represents the best comprehensive low-temperature thermal insulation solution available.
This material serves as both cold and thermal insulation, with applications ranging from deep cold areas to thermal states. It maintains performance over time without deterioration and provides excellent fire and earthquake resistance. Cellular glass offers safe, reliable, and durable performance in harsh environments including low temperature, deep cold, underground engineering, flammable/explosive areas, and chemically corrosive conditions. It's recognized as a "permanent thermal insulation material that never needs replacement."
