This research is mainly focused on the
impact of thermal modification on the transverse
anisotropy and dimensional stability of native beech
wood (Fagus sylvatica L.) and beech red heartwood.
Applied to two time-temperature regimes, the first
period of maximum temperature to 180° C and the
second to 230° C. The factor of anisotropy in native
beech wood is 1.29 and beech red heartwood is 1:24.
Dimensional stability of the native beech wood is
improved for 33.3% and beech red heartwood for
29.1%. The changing of the volume mass per thermal
modification of 6% is too small and does not affect
other properties.
