, also known as rock wool thermal insulation decorative board, is a kind of inorganic fiberboard made of basalt as the main raw material and melted at high temperature. In June 1981, rockwool panel
was successfully tested as a new kind of thermal insulation, flame insulation and sound absorption material.
Artificial inorganic fibers made of rockwool panel melted at high temperature have the characteristics of light weight, low thermal conductivity, heat absorption and non-flammability. Initial development is a common application type in construction, and it should meet the requirements of "Application Types and Basic Requirements of Building Adiabatic Materials".
Rock wool is one of the exterior wall insulation materials. When 90% of the market share of organic thermal insulation materials is stagnating, rock wool, as an inorganic material for exterior wall external thermal insulation reaching fire protection grade A, has ushered in an unprecedented market opportunity.
The price of rockwool panel has soared from 42 yuan per square meter to more than 200 yuan per square meter. Even so, the market demand is still in short supply.
The direct reason for the price increase of rockwool materials is the policy adjustment. With the fire in Beijing, Shanghai, Shenyang and other places, the fireproofing defects of organic materials for exterior wall thermal insulation, which are widely used at present, have been exposed. The Fire Bureau of the Ministry of Public Security issued the Notice on Further Defining the Requirements of Fire Supervision and Management of External Thermal Insulation Materials for Civil Buildings, which included the External Thermal Insulation Materials for Civil Buildings in the scope of Fire Design Audit, Fire Acceptance and Record Selective Examination of Construction Projects, and stipulated that External Thermal Insulation Materials for Civil Building.
