History

Grodan is a subsidiary of the Rockwool Group, which started the commercial production of stone wool in Hedehusene, Denmark in 1937. In 1949, Rockwool opened a manufacturing plant in IJmuiden, the Netherlands, relocating this facility to Roermond in 1968. One year later, Rockwool in Denmark founded Grodan to focus on production of stone wool substrate for the horticulture sector. In 1979, Grodan established itself in the Netherlands at the Rockwool complex in Roermond.


Around the new Millennium, Grodan profiled itself more as a supplier of total solutions: a combination of clean and manageable substrate, advising and support services. As part of this, the concepts of sustainable business became one of Grodan’s most important concerns. Recognition followed quickly. Grodan was the first substrate supplier to obtain ISO 9001/14001 certification, the Kiwa Keur (quality certificate) and the European Eco-label. At the same time, Grodan extended its reach further and further. It is now a worldwide enterprise, active in over sixty countries, from America to Asia.
