AB Permeability of wood is a wood property which strongly affects a process of drying wood, as well as steaming, boiling and wood impregnation. The low permeability of the most industry treated wood causes investigating the ways which increase the permeability of wood. The one of the considered methods is drying of wood with the aid microwave radiation which causes rotation and friction of water molecules, thus the temperature and the pressure inside the wood are growing up. As a result of raised pressure are crackled cell walls which makes the wood structure more permeable in transverse direction, but in longitudinal direction the wood speciemens treated with microwave radiation don't analyse differences in the permeability in comparison with unmodified wood.
