Rockwool A/S is a Danish multinational corporation and the world's leading manufacturer of stone wool insulation products, also known as the ROCKWOOL Group, headquartered in Hedehusene near Copenhagen. Founded in 1909 as a gravel mining company, it shifted to mineral wool production in the 1930s, becoming a publicly listed entity on the Copenhagen Stock Exchange in 1995 after generations of family ownership by the Kähler family.

Its diverse portfolio extends to acoustic ceilings under the Rockfon brand, noise and vibration control systems, horticultural substrates for precision growing, facade panels, and engineered fibers for marine, offshore, and process industries. With 42 to 45 manufacturing facilities across 38 countries in Europe, North America, and Asia, Rockwool A/S employs over 12,700 people and generates the majority of sales from Western Europe, serving sectors from construction to agriculture while emphasizing lifelong durability and environmental conservation.
