Perlite and pumice were used to achieve high thermal resistance, and low density. Experimentation was conducted for determining R-values of perlite-pumice-cement (PPC) panels at different moisture content values. Dry and moist sample panels were tested with and without soil and moss at the top where the one with the soil and plant coupling represents a green roof. Reverse heat leak method was used in determination of the R-values of the samples. Verification of theory was achieved via experimentation with an acceptable error range. Thermal diffusivity values of the developed samples were measured using flash method.enginfo:eu-repo/semantics/restrictedAccessArticle610511110.1016/j.jobe.2016.02.015InsulationPerlitePumiceMoistureR-valueThermal diffusivity2-s2.0-84961182508
