Analysis of Point Thermal Transmittance Depending on the Application of Thermal Breaking Anchors to Insulated Wall Specimen

Purpose: This study used physical testing methods to evaluate the peformance of point-type thermal bridges when installing acholars on wall structures. The aim of this study is to present highly reliable performance results of an insulation systems installed with thermal breakers in preparation for the implementation of net-zero energy buildings in the future. Method: Specifically, this paper focused on investigating the effect of thermal breakage on improving the insulation performance of wall structures by comparing the point-type thermal transmittance of test specimens with and without thermal breaking anchors installed. Based on the physical test results, the point-type thermal transmittance of the two cases was calculated using the thermal analysis calculation formula. Result: As a result of the physical experiment, the average thermal transmittance of the test specimen with thermal breaking anchors installed was found to be improved by approximately 13% compared to that of the test specimen installed with typical steel anchor.
