Thermal Bridging in Commercial Buildings – A Guide for Specifiers

Thermal bridging occurs when heat bypasses insulation through more conductive materials or structural elements within the building envelope. While often considered a detailing issue, its impact extends far beyond individual components – influencing whole-building performance, energy efficiency and occupant comfort.In commercial buildings, unaddressed thermal bridging can reduce the effectiveness of insulation, increase heating and cooling demand, and contribute to higher operational energy
