Wood processing industry is one of the most developed industries in Kosovo. In the framework of this industry, special importance should be given to the wood drying process, as a necessary process for further processing of wood. Therefore, a proper study of the drying quality of sawn boards which is using in residential buildings would be necessary. For the study were taken 13 subjects which are stretch throughout the territory of Kosovo. The study shows that the sawn timber in thickness 25-37mm, is draing well, but lacks air conditioning and equalization of moisture content throughout its thickness. While timber thickness 38-49mm and 50-70mm, did not dry enough, lack of moisture equalization throughout the thickness and conditioning is not done at all. The following results provide data for three thicknesses obtained in the study.
