This paper is focused on the problems of moisture reduction in old buildings. Wet walls
are very common problem of old buildings, but it can appears also in new buildings as well. The
moisture in the wall influence the insulation quality; bigger heat losses continuously cause
problems of worse heat balance, higher consumption of energy for heating and it can result in not
sufficient indoor conditions in such a room or building. Old rural residential buildings and also
agricultural buildings for housing of animals, storage of different materials, workshops etc. could
be repaired and reconstructed by the used of some special methods. The application of special
plaster can reduce the walls moisture as well as improve the thermal properties of the buildings
by reduction of thermal conductivity. This paper includes the results of laboratory experiments
focused on research of plaster properties (temperature, moisture and thermal conductivity) and
tests provided in the real building. Different measuring principles, enabling mutual comparison
of results were used for this research. The measurement results showed a significant effect of
high wall moisture on the heat losses. Differences between the walls improved by new tested
plaster and old untreated walls are discussed in this paper. Obtained results from this
measurements and findings may be useful for further research in this issue as well as for the
practical solutions for similar problems in many old buildings.
