Sažetak
The scope of this research was to monitor the distribution of moisture content of wood windows during one year period in continental part of Croatia. Measurements were taken on several different windows placed on comparable positions of the family house facing east, west, north and south. All the windows were partially protected with the roof overhang, leaving their lower parts exposed to weathering. There were 6 measuring positions along each window frame. In order to get the insight into the moisture content distribution over the cross section of the frame, three pairs of electrodes with insulated shafts were used at each measuring position. The results of the measurements in the outer zone of the frame indicate that, during one year period, the lowest maximum moisture content was detected on the window facing south (14, 5%), east (16, 5%), west (19, 5%) and the highest maximum was measured on the window facing north (21%). Minimum moisture content values also differ significantly, depending on the side of exposure. The lowest and the most uniform moisture content in inner zone is measured in south position (10 - 12 %), and the highest and widest moisture content range was detected in north (13 - 17 %). The distribution of moisture content between the outer, mid and inner zone also depends on the exposure side, the lowest differences were measured in south and the greatest in the north side. The greatest differences over the cross-section (up to 6%) were detected during winter period and the smallest (1 - 2 %) in summer. To minimise seasonal fluctuations of moisture content in wooden windows it is essential to follow the basic rules of physical protection, and pay due attention to proper installation and maintenance.
