A preliminary note on the role of moisture absorption rate in durability assessment

IRG/WP 08-20383

J J Morrell, L P Francis

The rate of moisture uptake was studied in 15 wood species using vermiculite at varying moisture levels as the exposure medium. As might be expected, moisture uptake varied widely among the species studied. While some of the more durable wood species were also resistant to moisture uptake, this was not always true. The results are discussed in relation to performance in under varying environmental exposures and the mechanisms for incorporating these data into models for predicting decay resistance in structures.

Keywords: water repellancy, decay resistance, building performance
