Global survey on durability variation – on the effect of the reference species
2016 - IRG/WP 16-20573
Climate change due to anthropogenic emissions is the largest environmental challenge of our time. Forest-based value chains play an important role in reducing the accumulation of CO2 in the atmosphere. Maximizing the use of wood to tackle climate change requires improved understanding of the service life of timber products. This information can best be obtained from field testing and while there i...

Corrosion of fasteners in furfurylated wood – final report after 9 years exposure outdoors
2017 - IRG/WP 17-40810
The corrosion of some common fastener materials – mild steel, stainless steel, zinc-coated steel, brass and Sanbond Z (nickel, zinc and chromate) coated steel – has been evaluated after nine years exposure outdoors in untreated Scots pine and furfurylated beech and southern yellow pine (SYP).
The furfurylation was carried out according to a process that resulted in approximately 40 % WPG (We...

Glued laminated poles - Progress report after 43 years of testing
2023 - IRG/WP 23-20692
In 1979, a number of glued laminated poles treated with CCA and creosote were placed in a greenhouse in Uppsala, in the Simlångsdalen test field in south-western Sweden and in a power lane in Vuollerim in northern Sweden, in order to study their resistance against biological degradation. The test poles were treated in a two-step process. All laminations of Scots pine (Pinus sylvestris) were first...

Performance of a noise barrier with different wood materials – results from a service trial after 25 years of exposure
2023 - IRG/WP 23-30776
In connection with the construction of the railway connection between Stockholm Arlanda airport and Stockholm city, an 11 km long noise barrier made of untreated European larch was built along the railway line. This provided an opportunity to implement a full-scale study comparing different untreated wood species and preservative treatments. Thus, in March 1996 ten test sections including untreate...
