Product Introduction
Foam glass is an inorganic non-metallic glass material produced by finely grinding and uniformly mixing crushed glass, foaming agents, modified additives, and foaming promoters, followed by high-temperature melting and foaming, and then annealing.
Scope of application
Foam glass can be widely used for thermal insulation of exterior walls and roofs in residential buildings. Thanks to its lightweight nature, fire resistance, non-combustibility, and long service life—comparable to the lifespan of the building itself—and given the growing global emphasis on environmental protection and sustainable living, foam glass is an ideal thermal insulation material for both exterior walls and roofs in residential construction.
Foam glass serves as both a cold-insulating and heat-insulating material, capable of withstanding a wide temperature range—from deep cryogenic to relatively high temperatures. Moreover, its significant value lies not only in its ability to remain unchanged over long periods of use but also in its inherent fire-resistant and seismic-resistant properties. When used in harsh environments such as low-temperature cryogenic applications, underground engineering projects, flammable and explosive settings, humid conditions, and chemically corrosive environments, foam glass proves not only reliable but also exceptionally durable, earning it the reputation of being an "insulation material that never needs replacing." Consequently, it is widely employed in thermal insulation, heat preservation, cold preservation, and corrosion-resistant lining of flue ducts in industries including petroleum, chemical processing, underground engineering, shipbuilding, and national defense and military industries.
