RELATIVE STABILITY O F SELECTED WOOD FLOORING SPECIES
(Ranked by dimensional change coefficient)*
The numbers in the chart reflect the dimensional change coefficient for the various species, measured as tangential shrink- age or swelling within normal moisture content limits of 6-14 percent. Tangential change values will normally reflect changes in plainsawn wood. Quartersawn wood will usually be more dimensionally stable than plainsawn.
The dimensional change coefficient can be used to calculate expected shrinkage or swelling. Simply multiply the change in moisture content by the change coefficient and then multiply by the width of the board.
