Ahlstrom to double its production capacity for specialty
reinforcements in the USA

Ahlstrom, a global leader in high performance fiber-based materials,
announced today that it plans to double its production capacity for
specialty glassfiber reinforcements in the USA to meet the fast
growing demand especially within the wind energy markets. The
capacity increase will be implemented in two phases by the end of
2011, and the total investment value is estimated to be approximately
EUR 7 million.

In the first phase Ahlstrom will invest approximately EUR 3 million
in 2008 and install new machinery at the facility. The second phase,
in 2009-2011 will include new production lines, and the investment
value is estimated to be approximately EUR 4 million. In North
America, the annual growth in demand for reinforcements is expected
to be 20% for the wind energy sector and 5% in the marine markets.
The Bishopville facility currently serves both the North and South
American reinforcement markets and will support the expansion of
Ahlstrom's glass nonwovens production into Asia."We are pleased to see that our current and potential customers
appreciate our presence in the American market. These investments
will strengthen our commitment and support the growth in the wind and
marine industries", says Tommi Björnman, Senior Vice President, Glass
Nonwovens.
