White spruce wood
White spruce is an important source of pulp wood and construction-grade timber. Its long, tough fibers produce high quality pulp, used to make different sorts of paper, molded products, insulating panels and particulate panels.
Its wood is light, tender and moderately solid. It is used to make panels, planks and beams for the construction industry, crates and boxes, doors, roof panels and other paneling.
Its wood is also highly prized by makers of sounding boards for pianos and violins, and for oars and paddles.
