Hygroscopic Simulations

The determination of the development of the moisture content as a result of improvements, for example, inlaying heat insulation or the insertion of hydrophobic plasters, describes an almost insoluble problem because of the reason that existing standards can not give any approach towards reality.
 
To get realistic results of the transient hygroscopic calculation of multi-layered components under natural climatic conditions, the program WUFI, which was developed by the ‘Frauenhofer Institut für Bauphysik IBP’ is used.
 
With this program, the coupled heat- and moisture transport can be mapped in building constructions over several years. The assessment of reconstruction-arrangements becomes feasible as well as solutions of questions regarding moisture behaviour at newly developed structures.
