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...

Tree bark as a renewable source of wood protection materials for building applications (BarkBuild)
2023 - IRG/WP 23-30792
The BarkBuild project aims to address climate change mitigation by developing new, sustainable, and long-lasting wood building materials with low environmental impact. The project focuses on developing bark-based wood protection and building formulations that demonstrate technical performance, safety, and sustainability in both outdoor and indoor applications. The research objectives of the projec...

Adhesion and performance of exterior wood coatings on chemically and thermally modified wood – Results from 5.5 years outdoor exposure
2023 - IRG/WP 23-40964
Non-durable softwood and hardwood species were treated with the water-soluble cyclic N-methylol compounds 1,3-dimethylol-4,5-dihydroxyethyleneurea (DMDHEU) and methylated DMDHEU. One half of the modified specimens were coated with a waterborne acrylic coating system prior a natural weathering for 5.5 years according to EN 927-3 (2020). By frequent evaluations, the impact of chemical modifications ...

Short-term absorption of water and coatings on thermally modified blue-stained spruce wood
2023 - IRG/WP 23-40984
The importance of wood has been increasing in the last decades. Among conifers, predominantly spruce (Picea abies) wood is often used in building constructions in Europe. Namely for construction and facades of buildings, decking and fences. Due to the increased public concerns about biocides, alternative techniques for protection, such as thermal modification and protection by construction, are ga...

Japanese traditional wooden building construction project in Bangkok - Part 1 Project outline, building implementation and effects
2023 - IRG/WP 23-40992
The purpose of this project is to build new ways to utilize wooden resources in Japan. Japan's forestry industry is in decline despite its abundant forest resources due to a lack of successors and other reasons. Meanwhile, in Southeast Asian countries, reinforced concrete houses, which are not suited to the climate, are on the rise due to a lack of wood and technology. To solve these problems in b...

Enhanced durability of bio-based materials for green building
2023 - IRG/WP 23-50382
Wood protection technologies provide tools to enhance the durability of bio-based materials for green building. Both wood and related bio-based material are regarded as eminent for green building. It allows to underpin several of the United Nations sustainable development goals and is regarded critical for the Green Deal objectives of the EU. Nevertheless, to enhance the potential it needs to be b...

Investigating moisture dynamics and fungal decay risk: integrating X-ray CT visualization and simulation benchmarks through a Fungal Control Unit
2024 - IRG/WP 24-11045
Wood is susceptible to fungal attack and over time the structural integrity can be compromised. This risk is of course strongly related to moisture dynamics, as moisture is needed for fungal growth. While existing methodologies, such as lab and field tests, provide valuable insights into wood decay, they often fall short in replicating real-life conditions, particularly within the intricacies of t...

Exposure tests on railroad ties treated with DOT
2024 - IRG/WP 24-20705
Keruing railroad ties were treated with disodium octaborate tetrahydrate (DOT) to retentions of 0.7 to 1.7% boric acid equivalent (BAE) and selected borate treated ties were subsequently over treated with creosote/diesel fuel mixture. The treated ties were exposed in a simulated railway track test bed in Malaysia. The leaching of borate was measured over 5 years. BAE in the ties after 5 years of e...

Evaluation of the water exclusion ability and inherent bioactivity of heartwood against decay in Japanese and European wood species via above-ground exposure and water absorption tests
2024 - IRG/WP 24-40998
The natural durability of wood has been thought to mainly depend on bioactive extractives and the water exclusion ability. To clarify the contribution of each factor to wood durability, above-ground exposure tests were conducted on Japanese and European wood species. A double-layer test was carried out using heartwood specimens of four wood species, i.e., Japanese cedar, Japanese cypress, Scots pi...
