In this study, focus was made on the formulation and development of polymer-filler composite as an insulating material using local natural Emirati shale as a filler. Unsaturated polyester resin was blended with the filler with a given polymer/filler ratio and then transformed into solid upon thermo-set process. Three different filler sizes are used, size 1 <100μ, size 2 (100μ - 200μ) and size 3 (200μ - 300μ). The solid samples produced were then characterized in terms of physical– microstructural properties (i.e., bulk density, water absorption, and resistance to chemical reagents), thermal properties (i.e. thermal conductivity and thermogravimetric analysis (TGA)) and mechanical properties (compressive strength, flexural strength and tensile strength). From the experimental work, it can be concluded that the natural Emirati shale can be utilized to manufacture stable and compatible composite materials that can be used as insulating material. The prepared samples showed improvement in mechanical properties over the commercial heat insulators and comparable with the other building materials. The material showed outstanding tensile strength (20 MPa to 40 MPa) compared with that for the thermal insulating materials (less than 1 MPa). On the other hand, the prepared composite materials exhibited low values of thermal conductivity. Sandwiching of composite in wall structures by one-third of the total thickness will significantly reduce the overall heat transfer coefficient in building walls and many industrial applications by at least 57%. Consequently, one would say that Emirati shale-based composites show good characteristics in terms of thermal conductivity, water retention and mechanical strength. In addition, with such cheap and abundant filler from natural resources, it vii shows a promising thermal insulating material both for domestic and industrial applications
