Sep 15, 2010. /Lesprom Network/. UPM's Timber business will curtail its production in Finland during the 4Q 2010. Demand for sawn timber has decreased and due to the seasonal changes demand is estimated to further slow down towards the end of the year. Also high wood price in Finland has weakened the business' cost competitiveness in the markets, company said in a statement received by Lesprom Network. The production curtailments in Timber business and possible temporary lay-offs are to be carried out according to mill-specific plans. UPM Timber has curtailed its production also during the first half of 2010, and has closed down a sawmill in Heinola and a further processing mill in Parkano during the early 2010.
