International joint field trial on the moisture performance of wood – Set up and first results
2024 - IRG/WP 24-40996
Wood durability to decay stems from its inherent resistance to fungi resistance to fungi. In this regard, wood's ability to withstand moisture uptake plays an important role as the lower threshold for wood decay is a moisture content of 25%. However, the aspect of moisture resistance is not yet sufficiently emphasized as a durability factor, both in the assessment of durability as a material prope...

Outdoor termite resistance performance of zinc borate (Borogard® ZB) treated parallel strand lumber (PSL) – 15 years field test results
2024 - IRG/WP 24-40999
This report discloses the outdoor termite resistance performance of PSL samples treated with zinc borate at a dosage of 0.85% BAE and 1.72% BAE in Wuxi, China. The outdoor field trial lasted for 15 years and observations were made after 6 months, 3 years, 5 years 1 month, 6 years 6 months and 15 years. The retaining rates of B2O3 and ZnO in the final samples were also tested, and the hypothesis wa...

Field performance of preserved shakes and shingles
2024 - IRG/WP 24-41000
Wood shakes and shingles are used in applications where they are at risk of decay, either in sidewall (UC3.1) or roofing (UC3.2) applications. Material durability may come from using the heartwood of naturally durable species, using preservative treatments, or both. Through a series of long-term field tests, this paper explores the performance of naturally durable and preserved shakes and shingles...

Assessment of historical pilings from Lisbon
2024 - IRG/WP 24-41004
The renovation and rebuilding of areas in Lisbon has led to work on buildings constructed in the Pombaline downtown district. These buildings were constructed on wooden pilings, as a means of stabilising unstable soils and transfer the loads from buildings to soils with adequate bearing capacity. These methods also increased the resilience of the reconstruction works to future possible earthquakes...

Evaluation of mass timber materials for military and commercial trailer decking
2024 - IRG/WP 24-41009
In this study, CLT trailer decking was manufactured to current military trailer decking specifications, verified using PRG320 performance criteria, and treated with either waterborne or oil borne wood preservatives. Preliminary results show adequate uptake of preservative solution and subsequent testing shows minimal effect due to treatment. Field durability tests are also being conducted of treat...

Field facility for conducting wood durability tests at LSU Agricultural Center
2024 - IRG/WP 24-41012
Efforts by Louisiana State University Agricultural Center (LSU AgCenter) to conduct wood durability research on C. formosanus and other wood-related topics, have led to establishing three field research sites to test wood products against Formosan subterranean termites (New Orleans, La), and native subterranean termites (Franklinton, LA), and to test utility poles for outdoor exposure, decay resis...

Field test method for wood in above ground situation - The full CEN/TC 38 guideline for the Sandwich method. Part 1 - Determining the relative protective effectiveness of a wood preservative
2024 - IRG/WP 24-41013
The attached draft CEN Technical Specification (i.e. pre-EN standard) has been drafted in order to become an alternative to the Lap-Joint test method (EN 12037:23) for testing of wood in above ground situation and the draft CEN/TS Part 1 is specifically intended for determining the relative protective effectiveness of a wood preservative. The new draft CEN/TS is based on a test method developed by...

Timber circularity discussion: Waste hierarchy and prioritising reuse opportunities!
2024 - IRG/WP 24-50398
By following the waste hierarchy and prioritising reuse opportunities first before resorting to disposal in landfills, we can effectively sustainably manage timber resources. This approach helps to conserve natural resources, reduce energy consumption, minimize greenhouse gas emissions, and minimize the overall environmental footprint associated with timber production and disposal. It also promote...
