Experimental evaluation of insulation materials for walls and roofs and their impact on indoor thermal comfort under composite climate

► The impact of insulation materials to satisfy Energy Conservation Building Code. ► Computing U-factor & R-values for 112 wall and roof sections experimentally. ► Uncertainty analysis of the experimental data. ► Elastospray of thickness 50 mm satisfies ECBC & other insulations need higher thickness. ► Validation of results through two prototype buildings.
