Abstract: |
The hygrothermal performance of building envelopes has been the subject of intensive research over
past decades culna6ting in the development of a series of.advanced computer-based simulation model.
However, in spite of the considerable progmss that has been made, questioil-'.which is 'not, as yet, ful resolved is the coupled effect of temperature gradient on moiiture diffusion rates..:As'a result, the material muport -data,tisqd,~as input for these models, is generally determined f~om - isothermal permelbili measurementl, . This -paper describes two investigations in which moisture flux experiments were carried out on smaff-"e niitnw samples subjected to gradients in both teinpirature and humidity. In each a different experimental technique was used and different materials wem't' ted. .
