Sustainability in construction industry has become an issue when designing a new building [1] and the conventional on-site construction methods have long been criticised for imposing rigorous human health and safety risk, as well as causing significant environmental destruction [2]. Meanwhile, PCSP can be perceived as an alternative approaches in creating and maintaining the sustainable built environment. Finsen & Georgia (2011) [1] said that this wall system can maximise benefits from integrated strategies, which focus on all of the building’s materials and systems, as well as the way they interact. The number of studies on thermal insulation of exterior and interior panels in PCSP design is very limited compared to the research of lightweight for the panels in PCSP design. It should be noticed that an appropriate design of thermal insulation of exterior and interior panels in PCSP can significantly reduce the consumption of energy for space heating and cooling and eventually reduce the degradation of energy-quality and caused carbon dioxide (CO2) emissions, which is in line with the concept of sustainable building [3]. In hot countries such as Malaysia, the building’s wall should be able to retain heat of the day and release the heat during the night. Hence, the PCSP that applied in the building’s wall should have the suitable thermal performance in order to save the energy thermal capacity that required to maintain the internal temperature by help of air-conditioning system [4]. In order to develop and construct PCSP design with a good thermal insulation, an experimental work which includes three full-scaled specimens, control specimen (C), foamed concrete specimen (FC) and foamed concrete with added 30% of palm oil fuel ash (POFA) with similar size (300mm x 200 mm x 120mm) was conduct to study the thermal performance for each different design of mix proportion. The temperature variation of exterior and interior layer of panels were recorded to investigate the temperature difference for the three different panels and to compare the thermal performance between FC and FC+POFA panels with C panel. Meanwhile, the cube from these three types of specimens also been produced in order to observe the workability and compressive strength development. Different mix proportion of foamed concrete in PCSP were used to study the effect of the proportion on the properties of the panels especially in thermal properties.
