Foam glass is extensively used for thermal insulation in the exterior walls and roofs of residential buildings. Thanks to its lightweight, fire-resistant, waterproof, non-polluting, non-combustible, and long-lasting (matching the lifespan of the building) properties, coupled with the increasing environmental protection requirements for human survival, foam glass is an ideal wall insulation material and roof insulation material for residential buildings.

Foam glass serves as both a thermal insulation and a thermal preservation material, capable of withstanding a wide temperature range from extreme cold to high temperatures. Its significant value lies not only in its longevity without degradation but also in its inherent fire-resistant and shock-absorbent properties. When used in environments such as low-temperature deep-freezing, underground projects, flammable and explosive areas, humid conditions, and harsh chemical erosion, it is not only safe and reliable but also durable, earning it the title of "a non-replacement thermal insulation material." Therefore, it is widely applied in the oil and chemical industries, underground construction, shipbuilding, thermal insulation and preservation, and as lining for flue gas ducts.
