Buildings in general, consume and lose huge energy amounts through their heating and cooling systems. Thus, effective thermal insulation materials required to endow on energy shaving attainments. For this research, bark particles were used as raw materials for the manufacturing of low-density thermal insulation panels. The aim of this work was to determine the optimum density value of these panels in combination with their thermal conductivity and mechanical performance. Three panel densities, i.e. 250 kg/m 3 , 300 kg/m 3 and 350 kg/m 3 were used in this study. For each density, specimens for the thermal, physical (water absorption, thickness swelling) and mechanical (static bending, internal bond) assays had been analysed. As proposed by the results, the optimum conditions could be achieved at density levels of 350 kg/m 3 . All things considered, bark-based particleboards seem to be a very promising feedstock materials for their usage especially as interior thermal insulation panels, in the building sector.
