Mineral wool Mineral wool Mineral wool is any fibrous material formed by spinning or drawing molten mineral or rock materials such as slag and ceramics. Applications of mineral wool include thermal insulation (as both structural insulation and pipe insulation, though it is not as fire-resistant as high-temperature insulation wool), filtration, soundproofing, and hydroponic growth medium. Mineral wool is also known as "mineral fiber", "mineral cotton", "mineral fibre", "man-made mineral fibre" (MMMF), and "man-made vitreous fiber" (MMVF). The nomenclature of these wool products is simply the parent/raw material name in prefix to "wool". Specific mineral wool products are "stone wool" and "slag wool".
