    Abstract

    The fungal resistance of Norway spruce and Scots pine, thermally modified at 195°C and 210°C, was studied with a lap-joint field test. Untreated and TBTO and CCA impregnated wood materials were selected as reference materials. The evaluations were carried out after 1, 2 and 9 years of exposure. After 1 and 2 years mainly discoloration was detected. Significant differences in the decay ratings of untreated and thermally modified wood materials were detected after 9 years in the field. Thermal modification significantly increased the fungal resistance. The only wood material without any signs of decay was CCA-treated pine.
