The study deals with the assessment of breathing features of authentic building materials forming the traditional timber-framed dwellings in Kavaközü and Beypazarı regions (Ankara, Turkey) and Tarsus region (Mersin, Turkey). In Beypazarı and Kavaközü, the traditional dwellings were mostly composed of mudbrick masonry structure at the ground floor and timber frame structure with mudbrick infill at the upper level(s). In Tarsus, basically a masonry a structure composed of cut stone and stone mortar was observed at the ground floor while a timber-framed structure with rubble stone and mortar infill at upper floors. The building materials, forming the multi-layered wall sections of these dwellings, were investigated in terms of continuity of water vapour transmission along the timber frame wall and stone and mud brick masonry wall sections. The water vapour diffusion resistance index (μ) of each material layer was determined in this regard. The overall SD values for each wall section were also calculated by means of graphs showing equivalent air layer thickness of water vapour diffusion (SD) of each material layer versus its thickness. The data exhibited high water vapour permeability capacity of the materials layers forming highly-breathable timber-framed and masonry wall components while wall components using mudbrick and mud mortar infill were more breathable than the ones using stone masonry and rubble stone infill. Their highly-breathable nature is one of the fundamental property that has to be fulfilled by compatible repair materials.
