Rockwool Group entering the Indian market

The board of directors of Rockwool International A/S has today approved the investment in a green field factory in India. The new factory will be placed on the west coast of the Gujarat state - which has by far the highest population in India - in a special economic zone offering proper facilities.

India has planned large industrial projects in power and chemical plants for the next decades which will support the growth of an already buoyant market of technical insulation. The new factory will be designed to offer the proper product assortment to cope with this market demand. Capacity is expected around 30 000 tonnes.

This EUR 18.5 million investment will be carried through in a joint venture between Rockwool International A/S and KAEFER Punj Lloyd Group India - one of the market leaders in the Indian technical insulation market - which will take 25 % of the shares of the new company. The management team will be composed exclusively of Rockwool managers.

With this investment the Rockwool Group is entering a new high potential market, and opens opportunities for exports to the Emirates and Saudi Arabia which are big markets for technical insulation.
