This paper presents the results of an investigation of the thermal properties of compressed blocks using a mixture of cement, clay, recycled paper, cardboard, and either polyethylene terephthalate (PET) or expanded polystyrene (EPS). The aim of this project was to examine the feasibility of an alternative material for use as cavity infill framed structures. Blocks were fabricated using six different recipes, three with a variable proportion of EPS, and three using different ratios of plastic, while keeping the other components consistent. A hydraulic press and a mould with dimensions of approximately 304.8mm (12in) wide by 304.8mm (12in) long by 101.6mm (4in) deep were used to form the blocks. The blocks were then allowed to cure for approximately two weeks. After curing, the thermal resistance of the blocks was determined using a hot-box apparatus. By applying a temperature gradient across the blocks, with a known heat flux value the thermal resistance value was determined. RSI values ranged from 1.59 to 1.79 K
