    Scots pine and Norway spruce planks were heat-treated at temperatures 190°C and 210°C. Water absorption of the specimens sawn out of the planks was determined according to the standard EN 927-5. The heartwood of the both wood species absorbed less water than sapwood. The heat-treatment decreased the water absorption of spruce sap- and heartwood and pine heartwood. The heat-treatment temperature had also an effect on water absorption. The higher was the temperature the lower was the level of absorbed moisture. However it was very remarkable to notice that the heat-treated sapwood of the pine absorbed more water than the untreated reference.
