When evaluating the test results of the long-term properties creep behaviour and dimensional stability of OSB and solid wood panels in the present paper, it was observed that the thermal post-treatment of the aforementioned wood-based materials
had varying effects on said properties. Whilst the creep behaviour, when tested according to ENV 1156 and DIN 68874-1, respectively, of heat-treated OSB improved in comparison to untreated control samples, SWP values were slightly lowered, although still on a high level. The dimensional stability, however, is not significantly influenced by the thermal modification. All values of OSB and SWP, respectively, were close to one another.
