Summary

Thermal bridging occurs in all construction types and is cause by areas of reduced insulation or where an element passes through the insulation. Wood has a lower thermal resistance than the insulation materials placed between the framing members. Therefore greater heat flow occurs through studs, plates, rails and joists than in other areas of the external wall or roof structures. This increase in thermal conductivity is referred to as thermal bridging. In general, thermal bridges can occur at any junction between building elements or where the building structure changes.
