Moisture Properties of Heat-Treated Scots Pine and Norway Spruce Sapwood Impregnated with Wood Preservatives
An experiment was conducted on commercially heat-treated (HT) Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies [L.] Karst.) sapwood collected from Ht Wood AB, Arvidsjaur, Sweden. Secondary treatment on HT wood was performed in laboratory scale by impregnating with water-repellent pres...
