Wood in buildings can be exposed to non-isothermal conditions. The moisture transport under 
these conditions is still not sufficiently understood, especially in its three anatomical directions 
and their combinations. The gradient in partial pressure of water vapour is also disputed as the 
single dominant driving potential for the hygroscopic moisture transport. In the project will be, at 
first, measured isothermal macroscopic properties of moisture transport and storage under 
multiple temperatures. Then, a new experimental setup for non-isothermal experiments will be 
designed and constructed. Using intended scenarios of non-isothermal conditions across the 
sample will be analysed gradients of the partial vapour pressure and of temperature as the two 
driving potentials responsible for the total moisture flow. Based on measured data will be 
derived functions of properties for their use in a single-Fickian numerical model with single 
driving potential. The relevancy of the model for the description of non-isothermal transport and 
storage behaviour of wood will be analysed.
