Auswirkungen von Innendämmungen auf das Feuchteverhalten von Fachwerkwänden unter zeitgerafften und überhöhten Klimabedingungen

The moisture behaviour of framework walls with interior thermal insulation under timeaccelerated and excessive conditions was investigated in the twin climate chamber of the Wilhelm-Klauditz-Institute. Insulations oriented towards materials which traditionally are used in half-timbered houses were combined with modern damping materials with straw-clay and brick sections. The wood moisture was measured radiometrically. Significant moisture changes were only noticed on wood which bordered on sections with an insulation of a mixture of clay, cork and straw. In this wall structure also the most important changes in moisture were measured in the materials used for the sections. While these moisture changes fluctuated within a mathematically comprehensible range and correlated closely with the hydric properties of the building materials ...
