Saint-Gobain buys Norway's Optimera Gruppen building materials group

The acquisition is part of Saint-Gobain's expansion into Scandinavia, which began last year with the purchase of Sweden's Dahl International, a distributor of heating, plumbing and sanitary equipment.

Optimera sales rose 11.4 pct last year to 514 mln eur, Saint-Gobain said, and employs over 1,400 people. Financial terms of the deal were not disclosed.
