Wood stability measures wood shrinkage or swelling. The numbers in the chart below reflect the dimensional change coefficient for various species. The change co-efficient can then be used to calculate expected shrinkage or swelling.
Change actually diminishes in a complete floor, because the boards’ proximity to each other restrains movement. The lower the change coefficient, the less your floor will move. Interestingly, some tropical woods such as brazilian cherry and merbau appear in this chart to have excellent moisture stability compared, for example, to domestic oak. Yet, actual installations of many tropical woods demonstrate significant movement in use. Please contact us to discuss wood tendencies as you consider which wood species is best for your floor.
