At pre-school age, during year 1983 the companys operations were expanding to process industry insulation projects in Finland and other countries in Europe. The strong growth spurt began from the Kaipola paper factory expansion project. Staying ahead in the development was ensured by investing in modern machinery and production lines. New offices and warehouses were built continually as the old ones got too small. During the massive growth years another sales office was based in Helsinki, to support the Jyväskylä main office.
