Raw materials: Rock wool is mainly made of volcanic rock or kaolin and mineral wool, which is made by high-temperature heating and special technology, and has a fine, soft, silvery white and grayish white fibrous structure. Mineral wool, on the other hand, is made of natural mineral fibers, such as magnesite and silicate rock, which are processed by pyrolysis, twisting, washing and other processes. It has a thin rod-like structure, dark color and hard hand feel.
Performance: Rock wool board has the characteristics of fire prevention, heat preservation, sound absorption and noise reduction, and non-corrosiveness. Mineral wool board has the characteristics of excellent decorative effect (plane roller pattern, relief, three-dimensional modeling), good thermal insulation performance, sound absorption and noise reduction, safety and fire prevention (incombustible or difficult to burn).
Application scenario: Rock wool board is mostly used in industrial buildings because of its fireproof performance. Because of its decorative effect and sound absorption and noise reduction performance, mineral wool board is mainly used in conference halls, libraries, concert halls, high-end hotels, gymnasiums, hospitals, office buildings and other places with sound absorption requirements.
Generally speaking, there are significant differences between rock wool and mineral wool in many aspects. When choosing to use, you can choose according to the actual needs and scenarios.
