Is aluminum foil ceramic fiber board classified as an organic board or an inorganic board?

Aluminum foil ceramic fiber board belongs to inorganic boards.

Aluminum foil ceramic fiber board is mainly composed of ceramic fiber and aluminum foil. The ceramic fiber is a fibrous lightweight refractory material, primarily made of minerals such as alumina (Al₂O₃) and silica (SiO₂), which are inorganic non-metallic materials. It has advantages such as light weight, high-temperature resistance, good thermal stability, low thermal conductivity, low specific heat, and resistance to mechanical vibration. Aluminum foil, as a metallic material, is also considered inorganic. Therefore, aluminum foil ceramic fiber board, composed of these two inorganic materials, is classified as an inorganic board. This type of board offers excellent fire resistance, thermal insulation, and heat preservation, and is widely used in industrial, construction, and marine applications for insulation, thermal protection, and fire separation.
