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...

Douglas-fir PSL Treated with Oilborne Copper Naphthenate – Treatment Experience & Efficacy
2014 - IRG/WP 14-40687
Treating characteristics, field stake efficacy and the results from treatment trials for oilborne copper naphthenate (CuNap) and Douglas-fir parallel strand lumber (PSL) are summarized in this paper. Treatment with a P9 Type-C based solution in laboratory tests showed full cross section penetration of large cross sections could be achieved. Commercial treatment trials using a P9 Type-A solution ...

Weather degradation of thin wood samples
2016 - IRG/WP 16-20578
Untreated wooden surfaces degrade when exposed to varying doses of natural weathering. In this study, thin wood samples were studied for weathering effects with the aim of modeling the degradation utilizing Near-infrared hyperspectral imaging. Several sets of samples were exposed outdoors for time intervals from 0 to 21 days, and one set of samples was exposed to UV-radiation in a laboratory chamb...
