A numerical calculation is used for hygrothermal assessment of different wall assemblies. Interior thermal insulation systems using lime-pozzolana, calcium silicate, vacuum insulation panels and mineral wool which are applied on a common historical brick wall structure are analyzed. A comparison between vapor-open and vapor-tight systems is conducted. Moisture and temperature fields in the insulated wall and in the wooden beam-heads that are embedded in the insulated walls are carried out using WUFI and 3D Cube. The best alternative found is vapor-open system on the basis of lime-pozzolana.
