Thermal bridging occurs when there are gaps between materials and structural surfaces causing “cold spots”. This can have an effect on the heat loss of a building. Within the software you can make an allowance for thermal bridging on individual elements such as external wall when calculating your heat loss. 

If a SAP Report is available for the potential installation, then the thermal bridging allowance can be taken from there.
