COSTAA German Sylvestris Pine and Spruce Pine Softwood
The basic properties of spruce and pine are similar in, for example, the long fibers and strength in relation to weight. Differences come up in cell structure: the cell wall in pine sapwood does not close completely, enabling fluid to move freely. This makes chemical treatments like impregnation of pine sapwood possible.
In the heartwood of spruce and pine, the cell wall closes completely and it blocks or complicates movement of fluid. Due to lesser water absorption, spruce and pine heartwood have good weathering resistance in comparison to pine sapwood.
