In this paper, the procedure to evaluate the thermal resistance of insulation foam with complex shape on the safe side by measuring with the calibrated hot box method (JIS A 1420 Annex B) is discussed. CFD simulation was conducted under measurement situation of hot box method for flat insulation foams and complicated shape ones. The analysis results, such as thermal resistance of surface heat transfer and overall heat transmission, show good agreement with experimental results. CFD simulation is considered to be an effective method for evaluating heat insulation performance.
