Foam glass is extensively used for thermal insulation in the exterior walls and roofs of residential buildings. Due to its lightweight, fireproof, waterproof, non-polluting, non-combustible, and long lifespan (matching the building's lifespan), 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 heat preservation material, capable of adapting to a wide temperature range from extreme cold to high temperatures. Its significant value lies not only in its longevity without deterioration but also in its inherent fireproof and shock-resistant 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 extensively applied in the oil and chemical industries, underground construction, shipbuilding, thermal insulation and preservation, and flue lining anti-corrosion projects.
