Investigation of thermal and sound insulation properties of sapwood and heartwood of willow tree
BioResourcesThe heat and sound insulation properties of the heartwood and sapwood of willow (Salix alba L.) were investigated. Based on the experimental results, it was determined that the density value of the heartwood of the willow tree was higher than that of sapwood, while the moisture value was lower in the sapwood.
