Exterior Rock Wool Panels, Exterior Rock Wool Insulation Construction Plan - Zhejiang Building-Used Exterior Rock Wool Insulation. Rock wool panels are inorganic fiber boards made by high-temperature melting processing of basalt, which is the main raw material. Also known as rock wool thermal insulation and decorative panels. The artificially produced inorganic fibers from rock wool, after high-temperature melting processing, possess characteristics such as light weight, low thermal conductivity, heat absorption, and non-combustibility. Initially developed, they are commonly used in building applications, particularly in industrial buildings, and should comply with the provisions of "Application Types and Basic Requirements for Building Insulation Materials." In June 1981, the trial production of rock wool panels was successfully completed, marking a new type of thermal insulation, fire-retardant, and sound-absorbing material. Suitable for roof and wall insulation, tank and pipeline thermal insulation, etc.
