Ecological Building Systems are pleased to announce that Paderborn-based family business Calsitherm and the Bremen-based sales company Redstone have now joined forces. Ecological have exclusively supplied the Calsitherm range of calcium silicate boards and ancillary products for 15 years to Ireland and the UK.

Calsitherm is pursuing its growth strategy with the acquisition of the majority stake in Redstone. Both companies are among the largest system providers for calcium silicate based interior insulation solutions and mould prevention on the market. In the course of the merger, the strategy team led by managing partner of Calsitherm, Dr. Tobias Hölscher commented 

“With this step we are strengthening both companies and expanding the product portfolio to continue to provide all building materials related to healthy living and sustainable construction.”
