エネルギー効率へ焦点をあてる

京都議定書は、温室効果ガス排出量の国別削減を義務付けた国家間の最初の合意でした。 京都議定書は、1992年の地球サミットとして一般に知られている会議でほぼすべての国が署名した気候変動に関する国連枠組み条約(UNFCCC)から生まれました。 これはROCKWOOLの歴史において重要な出来事であり、断熱材がいかにCO2排出量の大幅な削減に貢献できるかを知らしめたのです。 また、エネルギー消費量とエネルギー依存度の削減方法について EU でも議論が始まりました。 その結果、2000年に発表されたEUの論文は、ブロック内の総エネルギー消費量の40.3%が建物から来ていると初めて文書化されました。

Always innovating

Constantly optimising the ROCKWOOL mineral fibre technology and pursuing new ideas have always been key priorities for the Group R&D organisation. In the 1970s, this led to the development of a fibre that could replace asbestos to reinforce materials and products such as bitumen, paints, adhesives and brackets. Launched in 1974, Spinrock Fibres were a radical innovation for the 1970s, demonstrating how looking for healthier, more sustainable and environmentally friendly products has always been part of ROCKWOOL’s DNA.

ROCKWOOL International A/S founded

In 1976, ROCKWOOL International A/S was set up as a holding company for the entire Group, during a decade that saw the business develop and expand significantly. In 1970, 50 percent of the shares of the Nederlandse Steewolfabrik in Roermond in the Netherlands were acquired, with the remaining 50 percent purchased in 1975. Also that year, 50 percent of the shares in ROCKWOOL AB are sold to the Swedish State, which already owned the other 50 percent. In 1977, the factory in Doense began operations and in 1978 the subsidiaries Grodania and Rockfon were set up. The end of the decade, 1979, saw the establishment of ROCKWOOL Limited in Bridgend, UK.

Tom Kähler: the next generation takes over

Tom Kähler was employed as Director for emerging enterprises in 1978 and became CEO in 1987, a position he held until 2004, when Eelco van Heel was appointed COO as part of a succession plan. Tom became Chairman of the Board in 2004. Before joining the ROCKWOOL Group in 1978, Tom Kähler worked for several companies after completing his education as civil engineer, including setting up Ecoterm, his own contracting company, with his brother-in-law Keld Jepsen. Tom played a key role when ROCKWOOL Group established itself in Canada and made its first real entrance in the North American stone wool insulation market.

Circular thinking

The development in the early 1970s of Spinrock fibres, which helped industries to replace asbestos,
led to ROCKWOOL’s recycling concept. Plant workers in Hedehusene found that old stone wool products could be recycled if they were ground and mixed into briquettes. The first briquettes were made in 1978 for Spinrock and in 1979, this process was tested and implemented in the plant in Hedehusene, creating the foundation for a comprehensive “circularity” concept. The recycling of ROCKWOOL Group’s own production waste was extended further in subsequent years, to cover recycling schemes for external construction waste and demolition waste.

Demonstration projects

Built during the second oil crisis of 1978-1980, the Hjortekær low-energy test houses in Denmark showed that with good workmanship, careful design and good insulation, the energy use of a building could be reduced to one-tenth of contemporary standards. The ROCKWOOL Group was a key contributor to this project.

I/S Kähler & Co founded; expansion continues

In 1962, I/S Kähler & Co was founded, with wholly or partly-owned limited companies in Denmark, Norway, Sweden and Germany. Later that decade, expansion continued with the acquisition of a factory in Moss, Norway in 1965 and the start of operations at the greenfield factory in Vamdrup, Denmark in 1966. Three years later, in 1969, the company signed a licence agreement with FLUMROC AG of Switzerland, and acquired 26 percent of its shares.

The Kähler family takes sole responsibility for the ROCKWOOL business

In 1962, the Kähler and Henriksen families agreed to split and establish two new companies. Jens Nørgaard, later to become CFO of the ROCKWOOL Group, proposed a new company structure with the ROCKWOOL activities in one group and all others – sand pits, the aerated concrete business and Hasle tiles – in another group. The Henriksen family then chose the group they preferred and the company’s activities were split accordingly. On 1 January 1962, the name was changed to I/S Kähler & Co., with the Kähler family taking sole responsibility for the ROCKWOOL business.

Rockfon and Grodan created

Acoustic insulation products marketed under the Rockfon brand were introduced in 1962 and would grow into the second-largest business activity in the ROCKWOOL portfolio. In 1968, a collaboration with Horticulturist O. Bagge Olsen led to the development of stone wool as a growing medium for the professional horticultural sector, based on Precision Growing principles. Established in 1969, the Grodan business is active today in more than 60 countries worldwide.

The power of partnership

On 2 April 1968 Horticulturist O. Bagge Olsen from the Danish Agricultural University (Landbohøjskolen) in Copenhagen met with ROCKWOOL employees Svein Melhus, Helge Høyer and J. Skjold Petersen to discuss the use of stone wool as an additive to sphagnum. For many years, O. Bagge Olsen had investigated the relationship between stone and crops, finding that plants grew particularly well in areas with a lot of basalt in the soil. A joint development project and a test program involving local cucumber grower Viggo Nielsen created the basis for developing the current Grodan business.

Claus Kähler later to be CEO for 24 years, was employed in 1948.

1958

Claus Kähler, 22 years as CEO

Claus Kähler began his career managing stone wool production, aerated concrete and the gravel pits in 1948. By that time, 82 people were employed in Hedehusene, with all operations run by one organisation. In the 1950s, Claus set up separate production entities and created the basis for future profitable growth: in Denmark, turnover expanded from DKK 2.5 million to DKK 20 million during the decade and technological expertise grew significantly. Claus Kähler became CEO of Henriksen & Kähler in 1958, holding the position for 22 years.

First use of spinning technology

In 1952, ROCKWOOL acquired the licence from Johns Manville in the USA to use spinners for drawing fibres. The new process used diabase rock instead of slag, creating fewer shots (small pieces of stone that have not been spun into fibres), lower densities and more robust fibres. The result was wool with a significantly higher and more homogeneous quality. In 1953, the 4-wheel spinner was introduced, dramatically increasing potential output, which has grown from 0.6 tonnes per hour in the early 1950s to over 20 tonnes per hour today. The year 1954 was a turning point, as production with added binder worked smoothly and the quantity of slabs produced overtook sewn mat products. Mat products however continued to be an important part of the product portfolio and in 1959, ROCKWOOL acquired a patent covering lamella mats for pipe insulation.

Verner Palmquist, innovator

Working with ROCKWOOL from 1941-85, Verner Palmquist joined as an electrician and went on to become Technical Director and head of R&D. During his career, he shared in some the group’s major developments. Verner was promoted to Technical Director following his involvement in the successful transition from steam-blown wool to spun stone wool. His curiosity and experiments led to the use of binder and the transition from loose stone wool to the wide range of products that we know today.

Gustav Kähler, engineer and manager

In 1948, Gustav Kähler was appointed Managing Director I/S Henriksen & Kähler and his son Claus Kähler became Deputy Director, responsible for operations. Ten years later, Claus Kähler became CEO. Gustav started his career in his father Valdemar Kähler’s company I/S H.J. Henriksen and V. Kähler in 1915 as a civil engineer, long before stone wool production began. Succeeding his father as partner in 1916, he played a vital role in the expansion of the business geographically as well into new areas, including stone wool.

Stone wool production licenced

I/S Henriksen and Kähler acquired the licence to produce stone wool in Denmark, Norway, Sweden and Germany from New Jersey, USA-based Baldwin-Hill. The production process, based at the time on steam-blown fibres, was used to make loose wool and sewn mat products. It was a further 17 years before the more efficient and versatile spun wool production process was introduced.

Finn Henriksen was on a study tour to the US and saw a good opportunity to use the company's stone deposits for stone wool production.

1935

Finn Henriksen, inspired by a study tour

The son of [industrialist] H.J. Henriksen, Finn Henriksen saw stone wool production during a study tour to the USA. On his return to Denmark, he joined I/S Henriksen and Kähler established by his father and Valdemar Kähler, which invested USD 5,000 to licence stone wool technology from Baldwin-Hill. The foundation of ROCKWOOL Group stone wool production was laid.

Stone wool production in Denmark

The stone wool plant in Hedehusene, Denmark, began production. It burned down in 1938 but was rebuilt the same year. Also that same year, production of ROCKWOOL mineral wool began in Skövde in Sweden and Larvik in Norway. By 1939, total production had risen to 2,000 tonnes per year in Hedehusene alone.
