Another location associated with thermal bridging is the intersection of the floor slab and the wall.
Figure 4.3.3 shows such a bridge in a metal stud wall with a lightweight exterior finish and a steel
frame (Steven Winter Associates). In the alternative design the slab and beam are moved back so
that the insulation is continuous across the floor slab. A fire stop must be provided at the slab edge.
