Fungal damages in Norwegian massive timber elements – causes and measures
2019 - IRG/WP 19-40879
Massive wood elements are relatively new in Norway but the use is growing quickly, primarily the use of cross-laminated timber (CLT). Moisture performance of massive timber elements has been examined by some researchers, but more knowledge is needed. There is uncertainty regarding the need for vapour barriers or retarders in roof assemblies, and for practical reasons buildings are rarely assembled...

Effect of long-term immersion in fresh and salt water on mould growth on Scots pine (Pinus Sylvestris L.) wood
2020 - IRG/WP 20-10962
Wood exposed outdoors will eventually be degraded by fungi, depending on exposure and material characteristics. Numerous wooden constructions in the Røros municipality have existed since the 17th century, but wood used in recent repairs have decayed faster than expected. Before 1970 timber was mainly transported by log driving or rafting, and the logs were immersed in water for longer or shorter ...

Moisture and temperature conditions in an old, highly moisture-loaded timber building in the Røros municipality, Norway
2020 - IRG/WP 20-10966
A 150 years old log building near Røros, Norway, has been in active use as a cowshed since its erection. The animals are kept inside the cowshed all winter and this causes a situation of a high moisture load on the wooden floor, wooden walls and ceiling. Logging of temperature and humidity over one year shows that there are favourable levels of moisture in the wood and air for development of moul...

Introduction to the project ‘Deterioration and decay of wooden cultural heritage in Arctic and Alpine environments’ (ArcticAlpineDecay)
2022 - IRG/WP 22-10997
The Arctic is already affected by climate change, and this is expected to accelerate over the coming decades. Alpine regions in Norway are projected to face similar challenges. Current knowledge on Norwegian wooden cultural heritage in Arctic and Alpine regions is scattered and contains significant knowledge gaps. Historically, - scientists, sectorial governance, tourist trade and commerce have ma...

Characterisation of fungal decay in cable car trestles in Svalbard
2023 - IRG/WP 23-11031
The Arctic will be strongly affected by climate change. In Svalbard the coal mining industry were established in the early 20th century. All man-made structures and sites dating before 1946 in Svalbard are protected by law and considered as cultural heritage. This included the massive cable car trestles that are constructed from untreated Norway spruce and mounted directly into the soil. We hereby...
