Experiences with an industrial system for controlled thermal wood modification in pressurized unsaturated steam
2014 - IRG/WP 14-40678
Thermal wood modification in pressurized reactors has a long history, but these processes are to date industrially scarcely used, because of the relatively complicated process equipment, compared to the more common high-temperature processes in kilns at atmospheric pressure. However, based on our practical experience with the FirmoLin® process, supported by recent scientific findings, it is foun...

Resistance of modified wood to termite attack assessed in laboratory and field testing: A review of internal research
2018 - IRG/WP 18-40824
Within the past decades, new wood modification technologies have been investigated in order to improve certain wood characteristics and enable the use of timber products for outdoor applications. Some of these non-biocidal technologies have been developed and commercialized recently. Thus, various material properties were studied intensively and shown to be improved. To a great extent, previous re...

Boron dual-treatments for Douglas-fir utility poles: Tracking boron migration over time
2019 - IRG/WP 19-30739
The potential for using boron pressure-treatment prior to over-treatment with conventional, heavy-duty wood preservatives to limit internal decay in-service was investigated in two field tests on Douglas-fir utility poles. Pole sections were pressure-treated with disodium octaborate tetrahydrate (DOT) and then over-treated with either pentachlorophenol or copper naphthenate in oil. Alternatively, ...

Comparison of residual Methylisothiocyanate (MITC) in Australian and South American hardwood and softwood treated with a solid compressed Dazomet fumigant stick
2024 - IRG/WP 24-20712
The efficacy of compressed dazomet sticks with or without a copper-based accelerant for control of internal decay of both softwood and hardwood species was examined in multiple field trials. Effective levels of methylisothiocyanate (MITC), the fungitoxic decomposition product of dazomet were found in Australian spotted gum (Corymbia spp) and Guyanese Wallaba (Eperua falcata) as well as in southern...
