As a construction material, wood is used in
structural elements and building envelope components
such as window frames and cladding. These wooden
components are exposed to wetting by rain either
directly (cladding) or as a result of a failure
(rain infiltration). When the moisture content
levels are within a certain range, mold growth and
rot can occur, which may be detrimental for the
health of the occupants, decrease structural
strength and destroy the aesthetic appearance of a
building. In the hygroscopic range (vapour phase), a
well-developed theory explains the absorption of...
