The Resistance of Some Commercially Thermally Modified American Hardwoods to Termites and Fungi
2022 - IRG/WP 22-40944
Thermally Modified Wood (TMW) is now being produced in the United States but there are few data on the durability of these materials. In this study, commercially-produced thermally modified yellow poplar (Liriodendron tulipifera), red maple (Acer rubrum), and white ash (Fraxinus americana) were evaluated for fungal and termite resistance. The resistance of the three TMW species against Gloeophyllu...

Accelerated surface mould testing for exterior wood treatment in Temperate, Tropical and Laboratory environments
2023 - IRG/WP 23-20699
Mould attack is a very common cause of discoloration on wooden surfaces and can subsequently promote development of wood decay by other organisms. Prevention of mould growth is relevant for both pigmented wood paints as well as more transparent systems with a high or low amount of binder. The use of commercial biocides has led to effective microbiological inhibition in many contexts, but the incre...

Establishing the minimum effective penetration of wood preservatives in the refractory heartwood of E. nitens
2023 - IRG/WP 23-30780
Conventional pressure treatment of many Australian hardwoods results in little to no penetration of heartwood and a non-uniform envelope treatment of <5 mm surrounding a mostly untreated core. This is a major issue for many of the low durability plantation hardwood timbers that are grown in Tasmania, which contain high percentages of heartwood. Long term studies on softwoods such as spruce decking...

Improving American Hardwoods Sustainability, Durability and Markets
2023 - IRG/WP 23-50378
The American hardwood industry, which dates back to the first European settlers, has a wealth of experience processing the native hardwoods of North America. The US hardwood resource is mainly located in the eastern United States, from Maine in the North to the Gulf of Mexico in the South and westwards to the Mississippi Valley. The USA has more temperate hardwood species than any other world regi...
