Thermal insulation materials include: polyurethane foam, polystyrene board, phenolic foam, ceramic fiber blanket, aluminum silicate blanket, aluminum oxide blanket, silicon carbide fiber, aerogel blanket, glass wool, rock wool, expanded perlite, micro nano insulation, foam cement, etc. Insulation materials generally refer to materials with a thermal coefficient less than or equal to 0.12. The development of insulation materials is rapid, and the use of good insulation technology and materials in industry and construction often yields twice the results with half the effort.

Insulation materials can be divided into organic insulation materials and inorganic insulation materials.

Organic insulation materials

Organic thermal insulation materials mainly include polyurethane foam, polystyrene board, EPS, XPS, phenolic foam, etc. Organic insulation materials have the advantages of light weight, good processability, high density, and good insulation effect. However, their disadvantages include poor aging resistance, large deformation coefficient, poor stability, poor safety, flammability, poor ecological protection, high construction difficulty, high engineering cost, limited resources, and difficulty in recycling.

Inorganic insulation materials

Inorganic thermal insulation materials are mainly concentrated on ceramic fiber blanket, aluminum silicate blanket, aluminum oxide, silicon carbide fiber, aerogel blanket, glass wool, rock wool, expanded perlite, micro nano thermal insulation, foam cement, inorganic active wall thermal insulation materials and other materials with certain thermal insulation effects, which can achieve B1 to A fire protection according to the formula.
