This course describes the interactions of wood and water and the effect on a number of properties – shrinking and swelling in particular. The course begins with lectures on gas behavior and humidity. This information serves as background for understanding interactions between temperature and humidity, and their impact on wood behavior. The information on wood and water relations is divided into two lectures. The first presents a review of wood structure, how wood holds water, how we calculate moisture content, why wood shrinks and swells, and how wood’s moisture content changes with changes in temperature and humidity. The second lecture on wood and water relations focuses on shrinking and swelling. Solid wood is presented first followed by unique issues with composite wood products such as restraint due to cross-lamination, the impact of densification, and variability in density. The course also includes information on common methods and tools used for measuring moisture content.
