Rockwool, also known as the ROCKWOOL Group, is a Danish multinational manufacturer of mineral wool products. The company makes insulation and roofing systems. Founded as Korsør Stenforretning in 1909 by Henrik Johan Henriksen and Valdemar Kähler as a gravel mining company, it shifted focus to mineral wool production in 1937. Headquartered in Hedehusene, Greater Copenhagen, Denmark, Rockwool has a global presence with 45 manufacturing facilities, sales offices, distributors, and partners in over 40 countries. Jes Munk Hansen is the current CEO, having assumed the role in September 2024. Thomas Kähler is the Chairman of the Board.
Rockwool's primary product is stone wool insulation, made from basalt rock and recycled materials, used in construction, industrial, and horticultural sectors. Key applications include thermal insulation, fire protection, and acoustics. The company offers a range of products like insulation rolls, slabs, and granulate, as well as specialized solutions like acoustic ceiling and wall systems (Rockfon) and growing media for horticulture (Grodan). Recent news includes the seizure of Rockwool's Russian assets by the Russian government in January 2026. In February 2026, UBS upgraded Rockwool's stock to "buy," citing strong North American growth and margin improvements. The rock wool insulation market is experiencing growth, with a projected size of $26.78 billion by 2032.
