Software for calculating the coupled heat and moisture transfer in building components

WUFI family animated WUFI calculation

WUFI® (Wärme und Feuchte instationär) is a software family which allows realistic calculation of the transient coupled one- and twodimensional heat and moisture transport in multi-layer building components exposed to natural weather. It is based on the newest findings regarding vapour diffusion and liquid transport in building materials and has been validated by detailed comparison with measurements obtained in the laboratory and on IBP's outdoor testing field.
