The goal of the study was to determine the influence of orientation, impregnation or the modification of wooden elements on the moisture content of different types of wood. Eight, the most important domestic wood species were used in respective research, namely: Norway spruce (Picea abies), European larch (Larix decidua), common beech (Fagus sylvatica), oak (Quercus sp.), sweet chestnut (Castanea sativa), scots pine (Pinus sylvestris), lime (Tilia sp.) and ash (Fraxinus sp.). Four wood preservation methods were applied: copper-ethanolamine based biocide, montan wax, thin acrylic coating and thermal modification. Wood moisture measurements on the samples located on the test stand were performed using a Gigamodule resistance meter with a Thermofox logger manufactured by Scanntronik. The measurements were carried out in the period between December 2015 and June 2016. The collected data was statistically analyzed and visualized. Measurements and analysis showed that the orientation of facade elements has a significant influence on the wood moisture content. The hypothesis that the thermal modification does not improve the water exclusion efficacy was confirmed at lime wood and rejected at all other samples. Treatment with aqueous emulsions of waxes can effectively reduce the water uptake. The data analysis has confirmed our hypothesis that there is a strong correlation between absorption, the ability of wood to remain dry and wood moisture content.
