Definition and Composition

Mineral wool board, also known as mineral wool decorative sound-absorbing board, is mainly processed from granular cotton through special techniques. These granular cotton are formed by melting industrial waste at high temperatures, adding other additives, and undergoing multiple processes such as batching, molding, drying, embossing, coating, and cutting. Mineral wool board is completely asbestos free, so it does not produce needle shaped dust and is safe and harmless to human health.

Performance characteristics

‌Sound absorption and noise reduction‌：The fibers inside the mineral wool board interweave to form numerous micropores, which can effectively absorb sound waves and reduce indoor reverberation. Its absorption coefficient (NRC) is usually between 0.5 and 0.85, and the NRC of high absorption mineral wool board can reach 0.85.

‌Fire performance‌：Mineral wool board is mainly composed of non combustible granular cotton, which can effectively delay the spread of fire and has a long fire resistance time. It is an ideal fireproof ceiling material.

‌moisture resistance‌：High quality mineral wool board can maintain its deformation resistance even in environments with relative humidity up to 99%, making it particularly suitable for humid environments.

‌environmentally‌：Mineral wool board does not contain asbestos and other harmful substances, and has good environmental performance. Some models of products can be used in places with high cleanliness requirements such as hospitals and clean rooms.

‌processability‌：Mineral wool board is easy to cut and install, lightweight, and convenient for construction.
