Representative data sets of wood-based materials created for moisture control analysis by hygrothermal simulation

For wooden constructions, questions concerning moisture control design based on heat and moisture transfer are crucial, since wood and wood-based materials are particularly sensitive to moisture. Hygrothermal simulation models are state of the art, especially for the design of moisture-sensitive building components. However, the relevant material properties of specific wood-based products like moisture storage or liquid water transport parameters are often not available. Therefore, within a research project, generic data sets for eight product groups have been created. With the help of hygrothermal simulations, the impact of the generated generic data sets is compared to that of simulations with real measured data sets. The results showed that under normal and uncritical moisture conditions, the generic data sets well represent the behavior of the components and are therefore well suited for design purposes.
