US-based conglomerate Carlisle is selling the non-roofing and waterproofing unit of its German company, PDT Phoenix, to the Datwyler Group of Altdorf, Switzerland. The business unit makes elastomer profiles for use in applications for tunnels, rail, windows and facades and was acquired as part of Carlisle’s acquisition of PDT in 2011. Sales of the divested unit are approximately EUR35 million. Carlisle will retain the roofing and waterproofing business as the European centre for Carlisle Construction Materials. The transaction is subject to customary closing conditions, including obtaining regulatory approvals, and is expected to close by 2 January 2012. (PRA)
