Within the framework of measures aimed at saving the Wisla's wooden heritage,
thermal research has been carried out, allowing for a qualitative thermal assessment
of partitions of a historic wooden log house, which was subjected to modifications at
the beginning of the twentieth century. Differences in the temperature values on the
outer partitions and the ground floor were indicated. Simulations of changes in
internal surface temperature of the wooden wall were carried out in place without
thermal bridges.
