ROCKWOOL Ltd. in the UK & Ireland
Our UK manufacturing plant near Bridgend in South Wales employs around 350 people producing ROCKWOOL stone wool on our state of the art line and packaging facility. Together with customer support, sales and marketing teams based in Hammersmith and Dublin, ROCKWOOL serves the whole of the UK and Ireland.
The company story stretches back for over a century, when the remarkable properties of stone wool were discovered in the early 1900s.
It all started in Hawaii, where the naturally-occurring wool-like material hung from trees near the active Kilauea volcano. When scientists found that it had exceptional fire protection and insulation qualities, work began on a manufacturing process to reproduce it commercially.
In 1937, Gustav Kahler brought the volcanic principle to Denmark and set up the first factory near Copenhagen, making building insulation that could cope with the tough Danish climate.
Having proved its success at home, the company began to expand abroad, first to Germany, and later throughout Europe and into international markets. Today, ROCKWOOL operates in more than 30 countries – with production in 14 territories from Canada in the West to Malaysia in the East.
The UK factory was built on a reclaimed industrial site in Bridgend, South Wales and opened in 1979. The plant expanded in 2009, opening a new production line, and now houses some of the most advanced stone wool manufacturing technology in the world.
