Abstract:
Heat treatment improves biological durability and dimensional stability of wood. The degree of improved properties depends significantly on heat treatment process parameters.

Pine and spruce boards were heat treated at 225 oC for 6 hours under steam. The panels were painted with coatings, which are used on exterior cladding, joinery and fences in Finland. Performance of the coated heat treated and untreated panels was monitored during five years exposure.

Moisture content of heat treated wood has been found to be in a lower level compared to not heat treated wood substrate. However, no decrease in surface growth of coated wood was detected.
