Based on the durability and moisture performance tests, factors addressing inherent durability and wetting ability were calculated for red oak and European oak grown in Slovenia. Red oak sapwood had a higher resistance dose (DRd = 878) than Norway spruce (DRd = 325), but only half that of European oak (DRd = 1767). Based on the previous studies, it can be concluded, that red oak has a similar relative dose of resistance (Drd rel) to larch or pine hardwood (Humar at al. 2019). The higher wood durability of European oak can be explained by the higher contents of extractives.
