Chemical protection of historic timber structures: Results and future needs
2010 - IRG/WP 10-40487
The paper concentrates on the analysis of the effectiveness of chemical protection for timber structures in the Russian State Museums “Kizhi” (Karelia) and “Vitoslavlitsy” (Novgorod).
The condition of historic timber was tested at the monuments treated with PCP, borax, potassium carbonate, boric acid, Pinotex chemicals in the 1970-80. Long-term analysis revealed that in many cases the...

Encapsulation Systems Combined with DOT Borate Treatments – The Future of Treated Crossties
2014 - IRG/WP 14-40670
Borates have been utilized in wood protection systems for many decades but only recently have been used in North America to treat crossties. This colorless, ordorless and very effective wood protection chemical has the ability to arrest and prevent the colonization of wood by both basidiomycete decay fungi and insects such as beetles and termites while ties are air seasoning or in service. Since ...

Exterior paint for the future - Will there be any dry-film preservatives left?
2017 - IRG/WP 17-50332
Wooden houses have a long tradition in several of the Nordic countries. Wood can be protected in various ways; constructional, chemically and by surface treatment. The use of various types of exterior paints as a surface treatment is a common way to prolong the durability of the wood. To further protect the painted surface against growth of fungi and algae, dry-film biocides remains an essential p...

Pest and pathogens threaten the sustainability of plantation forestry: Global research collaboration will define the future
2018 - IRG/WP 18-50341
Global plantation forestry is dominated by intensively managed stands of Pinus, Populus, Acacia and Eucalyptus species. The greater proportion of these plantations has been established in areas where the trees are non-native and have thus been separated from their natural enemies. In all documented cases, these plantations have initially been free of serious pest and disease problems. But as ti...

Future development of durability assessment of wood, according to typical usage of preservative-treated wood and naturally durable wood in Japan
2020 - IRG/WP 20-20675
A market of preserved wood products in Japan has two unique histories. First is the market shift to residential ground sills from utility poles and sleepers; the other is the stop of CCA treatment caused by the new effluent standard. In 2018, around 85% of preserved wood products used for residential ground sills were treated with non-CCA such as Cu-based agents. Since the market of treated wood h...

Wood above ground project – Results and future plans
2024 - IRG/WP 24-11041
In 2000, the Danish Technological Institute (DTI) initiated an extensive study to investigate the natural durability of wood. The study involved exposing wood in various orientations to assess its performance. A total of 35 wood material types were exposed at DTI test site in Taastrup, Denmark. Moisture content (MC) was measured through weighing for the initial five years, decay was assessed follo...
