About Rockwool International
Rockwool A/S also recognized as ROCKWOOL Group, is a prominent Danish multinational corporation that specializes in mineral wool products. Headquartered in Hedehusene, Greater Copenhagen, Denmark, the company boasts a research and development unit that employs around 100 specialists, all located within the Copenhagen headquarters.
Once the world's largest insulation manufacturer, Rockwool held that title until it was surpassed in market leadership by other companies. By 2020, approximately 90% of Rockwool's revenue stemmed from insulation products, with a remarkable 80% being generated from sales across Europe.
Historical Development
Rockwool commenced operations in 1937 as Korsør Stenforretning, founded by contractor Henrik Johan Henriksen and brickyard owner Valdemar Kähler, initially focusing on gravel extraction. Subsequently, the company won a significant contract for enhancing dykes at Saltbæk Vig and later acquired the site.
It expanded operations in 1938 by purchasing a chipping plant in Hedehusene, and by 1939, it had started producing mineral wool (stone wool), making use of an American license obtained by Finn Henriksen during his visit to the United States. This marked a definitive shift toward insulation manufacturing.
In 1960, the company split into two factions: H+H and I/S Kähler & Co., which was directed by Valdemar Kähler's grandson, Claus Kähler. His son, Tom Kähler, took a leadership role in 1992, and by 1998, Tom was appointed chairman, with Eelco van Heel as CEO.
The company was listed as "Rockwool International A/S" on the Copenhagen Stock Exchange in 1996, transitioning from a family-owned foundation to a publicly traded entity.
Rockwool expanded into the United States with its first plant opening in 2006 in Marshall County, Mississippi. This was followed by a strategic plant opening in Ranson, West Virginia, under its Roxul subsidiary in 2013.
However, the company faced controversies, such as being labeled an "International Sponsor of War" by Ukraine in 2022 for supplying the Russian Ministry of Defence.
