Classification of exterior wall insulation materials by material shape:
1. External wall insulation materials Loose insulation materials such as slag slag expansion vermiculite mineral cotton rock wool expanded perlite sawdust and rice hull, etc., it is not suitable for vibration and envelope structure.
2, plate-like thermal insulation materials: external wall insulation materials are generally loose loose insulation materials or chemical synthetic polyester and synthetic rubber materials, such as mineral wool board, slate, foam plastic board, cork board and organic Fibreboard (wooden board, particle board, straw board and sugar cane board, etc.), in addition to foam concrete slab, it has some properties of the original loose material, simple processing and convenient construction.
3, the overall thermal insulation material: generally use loose insulation materials for the aggregate, external wall insulation material pouring or spraying surface, such as vermiculite concrete, expanded perlite concrete, fly ash ceramsite concrete, clay ceramsite Concrete, pumice concrete, slag concrete, etc., these materials still have some properties of the original loose materials, good integrity, convenient construction, most of them belong to Class A non-combustible insulation materials.
