Density Ratings for Wood Decking (KG per Cubic Meter)

Wood Decking Wood Siding Wood Flooring All Species

A wood product's weight is determined by combining the density of the basic wood structure with the material's moisture content. The density of wood, exclusive of water, varies a great deal within and between species. Density variations wthin a particular species of approximately 10% should be considered normal. A wood's weight is always partially contingent on its moisture content, so moisture should always be taken into consideration. The figures below represent the density at approximately 12% moisture content.⁽¹⁾
