insulation properties of the insulation material should be A-level. 2, height greater than or equal to 60m less than 100m of the building, the thermal performance of the insulation material should not be lower than the B2 level. When using B2 insulation materials, each level should be set horizontal fire isolation zone. 3, height greater than or equal to 24m less than 60m of the building, the fire performance of the
insulation material should not be less than the B2 level. When using B2 insulation material, every two layers should be set horizontal fire isolation tape. 4, building height less than 24m, the burning performance of insulation materials should not be lower than the B2 level. Among them, when using B2 insulation materials, every three layers should be set horizontal fire isolation zone. Second, the production of raw
materials 1, the main material The main material is cement, adding hydrogen peroxide, calcium, fly ash and cement foam made of foam. Foam cement insulation board is currently the best wall insulation and insulation wall insulation fire insulation material, its advantages are: low thermal conductivity, thermal insulation effect is good, do not burn, waterproof, strong adhesion with the wall, high strength , Non-toxic
