Abstract Balsa (Ochroma pyramidale), which is the lowest density wood, is a useful species in various industries. In general, balsa can be divided into three types (low density: LD, middle density: MD, high density: HD). In this study, we classified the porosities of the three balsa types into through-pore porosity, blind-pore porosity, and closed-pore porosity. As a result, the total porosity of balsa showed a high positive (+) correlation with closed-pore porosity, but total porosity of balsa showed negative (−) correlations with blind-pore porosity and through-pore porosity. Such information can be useful when using balsa as a natural porous material.
