In known methods of preservative or upgrading heat treatment of wood, the starting material ( 2 ) is subjected to a selection process in order to select out wood with defects ( 6 ) (knots, cracks, resin ducts). A not inconsiderable part of the starting material is hereby not used to obtain thermally preserved wood. According to the invention the defects ( 6 ) are sawn out of the starting material, whereafter the remaining defect-free parts ( 14 - 1 ) are once again combined by finger jointing to form larger parts ( 16 ). The thus jointed wood structures ( 16 ) can be further assembled by lamination into even larger wood structures, the laminated wood structures ( 18 ). These can be applied particularly well as exterior cladding or as window or door frame in the building industry.
