Foam glass is widely used for thermal insulation in the exterior walls and roofs of residential buildings. Owing to its lightweight, fire-resistant, waterproof, non-polluting, non-combustible, and long lifespan (matching the building's lifespan), coupled with the increasing demand for environmental protection, 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 heat 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-retardant and shock-absorbent properties. When used in environments such as low-temperature deep-freezing, underground construction, 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 engineering, shipbuilding, thermal insulation and preservation, and flue lining anti-corrosion projects.
