Experimental evaluation of the effect of embedded insulating material and layered zone under roofing system

The aim of this study is to determine the effect of embedded insulating material and layered zone under roofing system by comparing the temperature reduction or rise to the conventional part as a reference. The insulating material use in this study is aluminium foil with thin insulating material, f...
