Improvements of wood surface layers by modifications

An intensive research on the development of materials and methods of application which can improve the durability of wood and woodcoatings is being performed in recent years. Wood properties such as dimensional stability, water repellency, resistance to biological attack, UV- and visible light stability and even mechanical properties can be significantly improved by applying chemical and thermal treatments which are briefly presented in this work. Wood properties can be improved by heat treatment, acetylation, and plasma treatment or by application of nanocoatings. Heat treated and acetylated wood are commercially applied abroad, while possibilities for commercial usage of other modification methods need yet to be confirmed. Because the properties of modified wood are significantly improved, it can be successfully used for cladding and fencing, for noise reduction barriers, for joinery and furniture in exterior, and also for flooring and furniture in interior applications.
