Mineral wool is an industrial product available for use in insulation and fire protection. It is artificially produced with the use of molten rock or furnace slag which can be spun to create a dense, woolly material which can be treated in a variety of ways for different uses. It comes in a loose fill format and a blanket style, allowing technicians to cut blankets to size for insulation; shaped products for pipes and other items are also available. Manufacturers may be able to produce custom components upon customer request, depending on the nature of a project.

This product has a number of properties which make it useful for insulation. It is fire resistant and can be installed for fireproofing or to create fire resistant barriers in structures containing flammable materials and other fire hazards. It also blocks sound and can be used to create sound booths or to limit noise from a factory floor. Mineral wool insulation can also be useful for differential temperature control in buildings where different rooms may have their own heating and cooling needs.

Loose fill can be blown or piped into walls and other structures to create insulation. The padding can be installed like other forms of sheet insulation and can also be wrapped around objects of interest such as chemical tanks. Contoured shapes of mineral wool can be clipped to pipes and other objects to create a tight-fitting insulation barrier to limit heat loss or transfer, depending on the setting.

Home improvement stores may sell mineral wool and may also order it for specific applications. For industrial projects, contractors can order directly from manufacturers and wholesalers to reduce costs. Companies specializing in blown insulation and related products can obtain a range of mineral wool grades for different applications, all rated in terms of the level of insulation and protection they provide. This product can be used in new construction, retrofits and renovations and meets the insulation standards set by regional building codes.

Products derived from rock are known as stone or stone wool, while cinder wall uses furnace slag as the raw material. Mineral wool is a potential irritant and must be handled with care. Protective clothing, goggles and respiratory protection must be worn when working with this product. The fibers can enter the skin, lungs or eyes and create irritation and discomfort. Prolonged exposure can lead to chronic inflammation and other health problems.
