Performance of Douglas-fir cross laminated timber (CLT) subjected to elevated humidity in a ground proximity field test for 6 years
2024 - IRG/WP 24-41010
The ability of insecticidal soil drenches or spray-on insecticide/fungicide treatments to protect mass timber elements exposed in a high moisture environment but out of direct soil contact was assessed using a modified AWPA ground proximity test established in 2017. Three-ply Douglas-fir CLT pieces measuring 305 x 355 x 105 mm (L x H x W) were installed at the Harrison Experimental Forest (HEF) (S...

Contribution of naturally durable wood use to Circular Economy - Understanding the classification system of natural durability and its variation within wood species
2025 - IRG/WP 25-50411
Total wood demand is shown by FAO to increase 49 percent between 2020 and 2050, regardless of deteriorating conditions such as deforestation and degradation due to fire and biological damages. Demand for wood as a building material is also projected by UNEP to increase significantly to 300 Gt in 2040. To address this situation, extension of the service life and re-use of wood are expected to make ...
