Experimental characterizing of liquid water uptake and release – key to understand moisture-induced decay risk analysis
2025 - IRG/WP 25-41020
Wood can absorb water vapour (sorption) or liquid water (capillarity). Moisture from liquid water (rain, spray water) is often a problem for the performance of wood products used in outdoor structures. Wood is prone to biodegradation when is it too moist for too long periods. Experimental studies that allow conclusions to be drawn about the practical use of wood water uptake are limited due to the...

Evaluation of moisture exclusion ability of wood using double-layer outdoor exposure tests
2025 - IRG/WP 25-41021
The material resistance of wood to decay must be due to the combined effects of heartwood extractives and the moisture content state. Evaluating the moisture exclusion ability of wood is important for assessing its durability in outdoor use. We conducted previously double-layer outdoor exposure tests and investigated the relationship between moisture content over time and the progress of decay usi...

A multi-dataset validation study of moisture prediction in Norway spruce wood exposed outdoors
2025 - IRG/WP 25-41029
Wood used in outdoor construction undergoes continuous cycles of wetting and drying, resulting in fluctuating moisture contents that directly influence its long-term durability. Excess moisture above a critical threshold leads to deterioration by fungal decay, limiting the service life of the structure. Service life models thus rely on accurate predictive models of moisture behaviour. However, cap...

Linking treatability with moisture dynamics
2025 - IRG/WP 25-41031
Wood preservation is inherently linked to the ability to penetrate treating liquids. The EN 147374 (2022) standard provides a methodology to assess treatability and allows to identify wood species in relation to treatability classes. Over the past decades, performance of wood species in applications in use class 3 has been linked both to the impact of moisture dynamics and the resistance against f...
