Spruce is a slow growing and straight coniferous tree with dense branches. The wood is yellowish white with no clear difference between the heartwood and sapwood. Growth rings are clearly visible in the wood. Spruce timber is dense and hard and therefore is an excellent material for load-bearing structures and exterior linings. Spruce timber is easily workable and its properties make it suitable for indoor as well as outdoor use. The density of the wood usually varies from 370 kg/m³ to 450 kg/m³, (Mc 12-15%).
