Abstract

Thermal bridge in windows can cause multiple problems, including heat loss and mold/condensation problems. The energy performance of window has been dramatically improved in recent years, however, mold/condensation are still challenging problems. This paper analyzed the relationship of thermal performance between the whole window and thermal bridging area. Also, it identified the factors which affect the local heat flow of window thermal bridging. The results show that the thermal performance of window thermal bridging area has no direct relationship with window U-value. The window type and the position of Low-e coating were identified as key factors affecting the thermal performance of window thermal bridging area.
