Ultra-structural observations on the degradation of wood surfaces during weathering
1987 - IRG/WP 2280
Radiata pine (Pinus radiata D. Don) sapwood was converted into blocks with a transverse face about 5 mm square and measuring 8 mm longitudinally. Transverse (T.S.), Radial (R.L.S.) and Tangential (T.L.S.) surfaces were prepared and specimens exposed to the weather inclined at 45° facing equatorially for periods of between 20-60 days. After 30 days exposure erosion of the middle lamella was observ...

Preservation conditions of wooden roofs of two historical churches in middle-Sweden
2025 - IRG/WP 25-41016
Assessment of biodegradation by the rot of shingles from the roofs of churches of Hammarby and Tångeråsa in mid-Sweden was done by studies with X-ray computer tomography. The study suggests that inner rot could be detected with CT, which was not always easily detected by visual inspection. In some cases, erosion from the weathered side was fairly large, but the inner wood part was found not to b...
