Around three and a half million timber-frame houses enhance the cultural landscape in Germany’s cities and communities. They normally feature wooden support structures of oak or spruce/pine in 18 to 24 cm thickness, filled in with handmade brick or clay straw with poles. The interior is counterbalanced with clay straw, and the exterior is plastered with a layer of clay or lime mortar, or visibly jointed.

At an outdoor temperature of -10° these walls maintain an interior temperature of 6 to 9 °C, which is far from the current indoor temperature standard of about 20 °C. This leads to condensation, as a result of which the wooden support structure becomes damp as well – with irreversible damage. As exterior insulation is not generally accepted under laws governing historically listed structures, energetic restoration of the timber-frame is possible only through interior insulation.

Within the framework of a project of the company Haacke-Cellco GmbH (Celle), an insulation panel based on corkboard was developed which meets all requirements for interior insulation in timber-frame houses, at acceptable prices.
