Cellular glass is an inorganic rigid insulation material that is non-toxic, environmentally friendly, and suitable for both cryogenic and high-temperature applications. It represents the most comprehensive low-temperature thermal insulation solution available.
This versatile material serves as both cold and thermal insulation, with applications ranging from deep cold areas to thermal states. Its long-term durability and resistance to deterioration make it essential for fire and earthquake prevention. Cellular glass maintains reliability in harsh environments including low temperature, underground engineering, and chemically corrosive conditions, earning its reputation as a "permanent thermal insulation material that never needs replacement".
