LoginThe aim of the study was to find out if the location of material has effect onmicrobiological findings. Material samples (n = 735) were taken from the buildingswith susceptible moisture damages. Viable fungal spores and bacteria were analysedfrom paperboard, insulation material and wood samples from inner and outer parts ofconstruction. Microbial biodiversity was largest in inner parts of construction. In wallcavity, insulation material had largest microbial diversity. Acremonium, Aspergillusversicolor, Stachybotrys, Trichoderma and Streptomyces are examples of the microbeswhich seemed to be indicative of moisture damages if found in materials locating inthe inner side of construction. According our results, the location of material affectsthe microbiology of the material. This information is useful in risk assessment.Possible transfer routes of microbes in different elements of building can be evaluatedby stratified sampling over structure.
