Mineral wool manufacturing facilities melt siliceous raw materials — including rock, slag, and glass — at high temperatures and spin or blow the molten material into fibrous form, which is then processed into insulation batts, blankets, loose-fill, or board products. Operations involve heavy industrial equipment, high-heat furnaces, continuous production lines, and significant raw material and finished goods warehousing. Product typically moves into the construction supply chain via distributors or direct to contractors.
