266 Section 2 Foundations and Framing
This leaves space for insulation where the extra lumber
would have been used. As can be seen in the figure, an-
other savings can be had by using header hangers instead
of trimmer studs. The hanger is nailed to the rough open-
ing stud and the header slips into the top of the hanger.
Steel connecting plates can be used on single top plates
to make splices and attach adjoining walls.
To gain maximum insulation, corners are con-
structed so they can be fully insulated. This can be
accomplished with the three-stud corner shown in
Figure 11‑5 or with a two-stud corner using drywall
clips to attach the interior drywall. A two-stud corner
is shown in Figure 11‑45.
