Spruce is a tree in the species of Picea, which constitutes of 35 coniferous evergreen trees of the Pinaceae family found in the north hemisphere and cold regions of the planet. Spruces are large trees which reach 20 to 60 meters tall when mature and we can distinguish them from their whorled branches and conical form. In the mountains of western Sweden scientists have discovered a species of spruce called “Old Tjikko” with an age of 9,950 years which is considered to be the world’s oldest living tree.
Spruces have two major advantages when compared to other trees. First advantage concerns the quality of Spruces timber which is regarded particularly high. The second advantage is related with its adaptability to hot climate and in high ground temperatures which results in high levels of timber elasticity.
Spruce is considered to be especially useful as a constructing material and it is often called with different classifications as North American timber, SPF (spruce, pine, fir) and Whitewood. Spruce timber can be used for many commercial uses, from general construction activities and boxes up to really specialized applications such as wooden aircrafts. It is worth mentioning that the first aircraft of Wright brothers, the famous Flyer, was manufactured from spruce timber.
