In this study three types of layered lightweight particleboard were produced by using different amounts of expandable polystyrene in the core layer as the filler material. The objective of this study was to compare the effect of varying amounts of expandable filler (5, 10 and 15 %) for two panel densities (450 and 500 kg/m3) and two panel thicknesses (16 and 19 mm) on the panel properties. The results showed that using expandable fillers has a significant effect on the bending properties, internal bond, edge screw withdrawal resistance, thickness swelling and water absorption. The surface soundness and face screw withdrawal resistance were not affected by the usage of expandable filler, as it depends mainly on the quality and density of the surface layer. Panel density and panel thickness also have significant influence on the physical and mechanical properties of the panels produced. Physical and mechanical properties of the boards did not dramatically change when the amount of expandable filler was increased from 5 to 15 %.
