Comparison of Different Insulation Materials with Thermal Conductivity Coefficients Based on Density and Temperature for Two Climate Zones

The selection of insulation material and the determination optimal thickness are very important for saving energy ensuring thermal comfort. There numerous studies in literature determining optimum thickness. In these studies, conductivity coefficient (k) is taken directly from standardized tables calculated. real applications, k value varies depending on production conditions, density temperature. For this reason, operating temperature should be considered when study, expanded polystyrene (EPS), extrude (XPS), glass wool rock with different densities were used as materials, coal natural gas fuel. Konya Sivas provinces, which 3rd 4th climate zones Turkey, a comparison was made using degree-day method function cost, thicknesses determined As result calculations Konya, climatic zone, found to 0.076 m EPS 30 kg·m−3, 0.037 XPS 0.082 100 0.051 150 kg·m−3. When fuel, EPS, XPS, 0.092, 0.061, 0.104, 0.078, respectively. province, kg·m−3 0.086 m, 0.044 0.092 0.058 m. 0.098, 0.069, 0.106, 0.081, comparing although unit price higher, its lower than that other materials all situations due low conductivity.
