ABSTRACT

The study comprised an analysis of dimensional changes in thin wood-based boards caused by cyclical changes in relative humidity at constant ambient temperature. Analyses were conducted on MDF, HDF, PB and OSB. As a result of these investigations it was found that final relative dimensional changes are significantly dependent on changes in dimensions occurring at individual stages of conditioning, with the first adsorption changes being most important. The lowest relative change in length determined in relation to the initial length was found for MDF board, while that in thickness – for HDF board.

Key words: MDF, HDF, PB, OSB, dimensional stability.
