Thermal bridge
A location where heat flows more readily through an assembly because of a conductive material or a break in insulation continuity.
Why it matters
Thermal bridges can affect energy use and interior surface temperatures. Adding nominal insulation does not necessarily correct a highly conductive connection.
In practice
A project example
A slab edge conducts heat through an otherwise insulated exterior wall.
