Performance of Chromated Copper Arsenic Treated and Untreated Papua New Guinea Timber Species in Marine Exposure after 95 weeks (664 days)
2025 - IRG/WP 25-11062
A Masters’ thesis on the topic was successfully completed and submitted in September 2024. The thesis reports on results obtained from exposure of five Papua New Guinea (PNG) timber species (obtained from secondary growth or plantation grown) after 218 days (31 weeks) in a marine environment in sub-tropical Queensland, Australia. The species studied were: Hopea iriana (Hopea, heavy), Vitex cofas...

Natural and enhanced durability of wood exposed above ground
2025 - IRG/WP 25-11079
Understanding and predicting the durability of wood is essential for ensuring its effective use, long-term reliability, and sustainability in various applications. To address this need, the "Wood Above Ground" project was initiated in 1999 at the Danish Technological Institute (DTI) to investigate the natural durability of wood species under a wide range of above-ground exposure scenarios. This ex...

Moisture uptake in CLT during the construction phase: real construction conditions versus specimens exposed to environment
2025 - IRG/WP 25-41019
The rapid growth in the use of Cross-Laminated Timber (CLT) in construction highlights the need to address durability concerns, particularly in regions with less experience in Mass Timber Construction and favourable climatic conditions for the biological degradation of wood, such as Mediterranean countries. A lack of awareness and deficient construction management can negatively impact the public ...

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...
