Abstract

To utilize a huge amount of oil palm trunk (Elaeis guineensis) biomass as wall insulation, its dimensional stability and insulation properties need to be improved. Thermal modification (TM) (without compression or densification) is one of the efficient methods widely used for improving insulation properties and dimensional stability of wood material, but such an existing method requires a complex system. In this work, the TM of oil palm wood with an initial density of 219 ± 34 kg/m3 was performed at 200 °C using a hot press machine. The optimum heat-treatment durations (2 h, 4 h, and 6 h) for their potential for insulation wall applications were explored. TM improved dimensional stability, sound-absorption coefficient, and thermal conductivity by approximately 66.7%, 26.7%, and 24.6%, respectively, but increased volatile organic compound (VOCs) emission compared with the control. Heat-treatment duration notably affected mass loss, density, and thermal conductivity. Compared with available natural material-based insulation walls, TM oil palm showed better insulation performance for all treatment durations. Thus, the heat-treatment duration of 2 h is suggested to save the energy consumption in the heat-treatment process while still achieving the same level of sound absorption, dimensional stability, and VOC emission performance as that of the long heat-treatment duration.
