Aerogel ceramic composite boards are widely used in wall insulation, pipe insulation, furnace insulation and other aspects due to their advantages such as fire resistance, moisture resistance, sound insulation and durability. According to authoritative reports, aerogel ceramic composite boards are a new type of composite door core filling material. They are mainly made of modified nano-materials such as aerogel powder, composite active clay, calcium aluminate cement, non-metallic slag tail powder, alkali activator and foaming agent. They are produced by advanced low-temperature foaming technology and chemical sintering process under medium and low temperature conditions. They are a kind of high-performance inorganic closed-cell energy-saving material with low water absorption, no expansion and no contraction. When this material is used in the core of the door, it can greatly improve the moisture resistance of the wooden door and can be stably used even in the humid southern regions. 
Due to the fact that the aerogel ceramic composite board is made of nano-aerogel, with its three-dimensional network structure of nano-pores, ultra-low thermal conductivity and the feature of being the lightest solid in the world, it has excellent flame-retardant performance and its fire resistance rating reaches Grade A. The wooden doors filled with this aerogel ceramic composite board have certain flame-retardant effects and thermal insulation performance. Even under high temperatures, their physical properties will not change, they will not deform, and their chemical properties will not change after being exposed to fire, safeguarding the safety of every family. 
Aerogel ceramic composite panels are environmentally friendly materials. Their production process does not require high temperatures or high pressure, and the products are harmless, pollution-free, and non-radioactive. When used as fillers in door panels to replace traditional wooden fillers, they can reduce the use of wood and contribute to achieving carbon peaking and carbon neutrality. Compared with traditional door cores, the main inorganic materials used in aerogel ceramic composite panels are also more environmentally friendly. According to authoritative test reports, the formaldehyde emission of aerogel ceramic composite panels is far lower than the national E1 standard limit.
