In this study, the effect of convection and radiation in porous insulation materials on theeffective thermal conductivity has been experimentally investigated in terms of the reinforcement. Theexperiments have been performed on two standard test apparatus and the other experimental setup inwhich an application is done. For this purpose, the glass wool materials are reinforced with lowemissivity and conductive materials, such as stretch nylon, thin foil and white paper, and their thermaleffective conductivities are determined. From experimental results, it is observed that the effectivethermal conductivity of porous insulation materials reinforced with thin foil is decreased at 0 o C and 10o C temperatures under the average temperature of 20 o C. The effective thermal conductivity of porousinsulation material reinforced with thin foil is decreased up to 9 %. In the applied experimental setup, itfound that the warming time of unreinforced ternary glass wool is 28,57 % slower than that of the otherreinforced sample. Also, the ETC of glass wool insulation materials improved by using low-reflectivitymaterials such as stretch nylon and white paper, which are similar to those of the unreinforced glass wool.From these results, it is seen that the radiation is an important mechanism and it can form the effectsexcept for standard behavior.
