The Rockwool Group expands in the US

At today’s meeting, the Board of Directors approved the plan to establish the
Rockwool Group’s first production facility in the US. The new plant will be
constructed in Marshall County, Mississippi, approximately 50 km from Memphis,
Tennessee. Subject to the successful completion of site due diligence in the
coming months, the plant is expected to be ready in 2014 and will, when
reaching full capacity, be able to deliver more than 100,000 tonnes of stone
wool insulation annually. The investment is expected to total around EUR 125
million.

Commenting on the expansion, Rockwool CEO Eelco van Heel said: “We have seen
strong interest from big Do-It-Yourself chains to offer our products to their
customers. The unique thermal, acoustic and fire safe qualities of our stone
wool insulation are very appreciated by their customers as well as those from
the Lumber Yard and Gypsum Supply Dealer segment of the market. With this new
plant in the Southern part of the US, we are happy to expand our geographical
coverage to new regions of the continent where we are currently not present.
The additional capacity will also support our strong growth in other key
insulation markets such as commercial buildings, flat roofs and industrial
applications”.

The Rockwool operations in North America have over the last years seen good
sales growth despite the otherwise troubled US construction sector. The US
market has been serviced from the Group’s two factories in Canada. In 2011,
sales in North America accounted for 8% of total Group sales but this share is
expected to grow in the coming years.
