Retention of rape oil ranged between 21,06 and 78,51 kg/m3 in fir specimens and between 11,20 and 90,32 kg/m3 in spruce specimens, while retention of CCB preservatives fluctuated between 1,68 and 10,05 kg/m3 in fir and be-tween 1,86 and 6,80 kg/m3 in spruce specimens. Penetration depth in all directions as well as impregnated area of cross sections of wood specimens were found to be lower in spruce than in fir for rape oil and, in most cases, for CCB preservative tested. The general conclusion is that both species are difficult to impregnation, but fir is more permeable than spruce.

- The objective of this study was to examine the retention (kg/m³) and the penetration depth (mm) as well as the impregnated area of cross sections (%) along the hole length, in fir (Abies borisii regis) and spruce (Picea excelsa) wood, after preservative treatment with rape oil and CCB preservative (3,2 %).

In order to determine the effect of direction (axial, lateral/radial or tangential) on pene-tration of rape oil and CCB preservative, the surfaces of the specimens were coated (laterally in all surfaces and in cross sections, respectively).
