Quirouette developed a series of design details for brick veneer/metal stud walls for cold climates,
in which the air barrier is generally applied outside of the studs but on the warm side of an outer
layer of rigid insulation. This allows the stud wall to be used as a space for the installation of
electrical and other services. Figure 4.3.4 shows a wall/foundation connection where the air barrier
is located between the stud wall and a layer of rigid insulation. The air barrier is applied to the
outside of the stud wall and a flexible connection is used at the interface of the wall and the
foundation. Locating the air barrier outside of the stud wall allows services to be installed in the wall
without having to worry about the air barrier.

The intersection of the stud wall and the floor slab is shown in Figure 4.3.5. The outer gypsum
board is carried over the floor slab to provide a continuous surface for the installation of the air
barrier. The vertical studs are shortened to accommodate deflection of the floor slab, preventing
damage to the interior gypsum.
