Exterior mineral wool board, exterior mineral wool insulation installation scheme - Zhejiang building exterior mineral wool insulation

Rock wool board is made ofBasaltInorganic fiberboard, produced by high-temperature melting and processing of main raw materials, also known as rock wool board.Thermal insulation decorative boardRock wool board is a man-made inorganic fiber processed through high-temperature melting, characterized by its light weight, low thermal conductivity, heat absorption, and non-flammability. Initially developed, it is commonly used in the construction industry and should comply with the "Application Types and Basic Requirements for Building Insulation Materials." In June 1981, the trial production of rock wool board was successful, marking it as a new type of thermal insulation, fire-retardant, and sound-absorbing material. It is suitable for roof and wall insulation, as well as tank and pipeline thermal insulation.

The rise in the price of mineral wool materials is directly attributed to policy adjustments. Following major fires in Beijing, Shanghai, Shenyang, and other areas, the fire prevention shortcomings of the currently widely used organic exterior wall insulation materials have been exposed. The Fire Department of the Ministry of Public Security issued a notice titled "Regarding Further Clarification of Requirements for Fire Supervision and Management of Civil Building External Insulation Materials," incorporating civil building external insulation materials into the scope of fire design review, fire acceptance, and random inspections for construction projects, and stipulating that civil building external insulation materials should ideally reach Grade A.
