SPRUCE LOGS (Picea abies)

Spruce is useful as a building wood, commonly referred to by several different names including North American timber, SPF (spruce, pine, fir) and whitewood. Spruce wood is used for many purposes, ranging from general construction work and crates to highly specialised uses in wooden aircraft, and as a tonewood in many musical instruments, including guitars, mandolins, cellos, violins, and the soundboard at the heart of a piano and the harp. The Wright Brothers' first aircraft was built of spruce.^{[citation needed]}

Because this species has no insect or decay resistance qualities after logging, it is generally recommended for construction purposes as indoor use only (ex. indoor drywall framing). Spruce wood, when left outside can not be expected to last more than 12–18 months depending on the type of climate it is exposed to.
