Wärmeschutz und Feuchteverhalten von Fachwerkwänden mit Innendämmungen - Versuche unter zeitgerafften Klimabedingungen

The moisture behaviour of framework walls with interior thermal insulation under time-accelerated and excessive conditions was investigated in the twin climate chamber of Wilhelm-Klauditz-Institut. The wood moisture was measured gravimetrically. Significant moisture changes were only noticed on wood which bordered on sections with an insulation of a mixture of clay, cork and straw. The change in wood moisture could not be calculated with simplified one-dimensional statements. In order to explain the unexpectedly high wood moisture, a moisture transport scheme was referred to corresponding to the real and multi-dimensional moisture flows.
