English abstract:
This article deals with the assessment of interior insulation systems for exterior walls. The influential factors for choosing a suitable interior insulation system are discussed considering moisture ingress from the outside and the inside, constructive parameters, possible thermal bridges and problematic constructive junctions.
The causes of damage especially by the mould growth on interior insulated walls are elaborated. The final, major part deals with measurements of interior insulations. Results from moisture and temperature measurements conducted over a three-year-period are compared with simulations´ results. The project represents an attempt to insulate a 19th century townhouse on the interior by using insulating wall panels made out of reeds and clay plaster. Using the HAM3D_VIE simulation program, insulation thicknesses, room climates, measured temperatures and relative humidity are compared.
In conclusion, analyses illustrate the effect of simulated insulation thicknesses on the risk of mould growth based on the isopleths-model, showing that the combination of reed and clay plaster insulating wall panels is a well-functioning interior insulation alternative.
