For self insulation exterior wall of the residential building, through the calculation method, the paper analyzes the effect of the different thermal bridge construction practices of the exterior wall on the average heat transfer coefficient. Based on the analysis, the thermal bridge construction practices will be further optimized. Analysis results show that the thermal bridge to adopt reasonable insulation measures and optimization of thermal bridge can greatly reduce the average heat transfer coefficient of exterior wall, increase the thermal resistance of exterior wall thermal bridge, improve the insulation performance of the wall. The research results will provide an important reference opinion for the self insulating exterior wall thermal bridge in heat insulation measures and optimization of construction practices.
