On the natural durability of RED MERANTI for window frames as a function of gross density wood
2018 - IRG/WP 18-10927
MERANTI is a wood species belonging to the family Dipterocarpaceae, in the genus SHOREA (Shorea spp.). The genus has approximately 196 species with four subgenera. The subgenus RUBROSHOREA is commonly named RED MERANTI (RM) and is found on the Malayan Island of Sarawak, Indonesia, with approximately 65 varieties (Symington 1943). According to Brazier (1956), the distribution of gross densities wi...

Comparative performance of wood/wood-based claddings predicted by four hygrothermal simulation tools
2019 - IRG/WP 19-20646
A number of hygrothermal numerical simulation packages are available, either wholly or partially dedicated to heat, air and moisture transfer simulations of building materials and wall assemblies. The objective of this work was to compare the hygrothermal responses and the moisture performance of western red cedar and composite wood claddings of a wood frame wall as predicted by four hygrothermal ...

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...

DURALARCH – Suitability of selected coloured coniferous heartwoods of different origin for their use in outdoor applications
2025 - IRG/WP 25-11064
For outdoor above-ground applications with high demands on biological durability, there are only a few softwoods available that also have high density and strength characteristics. One of the most important timbers with these material properties is Siberian larch (Larix sibirica, Larix gmelinii), which is available in sufficient quantities due to its large distribution area. Imports of Siberian la...

mpact of Fence Post Footings on Wood Post Durability
2025 - IRG/WP 25-41025
Residential wood fence posts may be dug directly into the ground, secured to a metal spike that goes into the ground, or secured to a concrete footing with a metal boot. It was hypothesised that by keeping wood posts out of the ground both spikes and boot attachments would increase protection against decay and termites and extend the service life of the post. After 9-years of exposure in Kincardin...
