Mineral wool is a material that is used as sound and thermal insulation. The term mineral wool includes glass wool, stone wool produced from the melt of igneous rocks (basalt, gabbro), and slag wool made from blast furnace slag melt.
Mineral wool consists of randomly intertwined individual fibers. Such a structure is obtained by blowing the molten material during the manufacturing process. Mineral wool is produced in the form of mats or slabs. Phenolic alcohols and a little oil are often used as a binder.
