Wall framing includes studs, wall plates and lintels that resist lateral loads and vertical loads from the upper floors, ceiling and roof. All framing lumber should be grade-stamped and have a moisture content not exceeding 19 per cent. See Table 24 (p. 288) for nailing requirements.
Insulation is usually installed in the stud spaces. If the stud space is not deep enough to contain the required level of insulation, wider studs, double walls, or rigid or semi-rigid insulation outside the stud space may be used. In all cases, the vapour control requirements presented in Chapter 5 must be observed.
Exterior wall studs are the vertical members to which the wall sheathing and cladding are attached. They are supported on a bottom plate and, in turn, support the top plate(s). Studs usually consist of 38 × 89 mm (2 × 4 in. nominal) or 38 × 140 mm (2 × 6 in. nominal) lumber and are commonly spaced 400 mm (16 in.) on centre. This spacing may be changed to 300 or 600 mm (12 or 24 in.), depending on the load and the limitations imposed by the type and thickness of the wall covering used (Table 25 on p. 290).
Additional rigid or semi-rigid insulation or batts installed between 38 × 38 mm (2 × 2 in.) horizontal furring strips can be attached to the inside of the studs, or rigid or semi-rigid insulation sheathing fastened to the outside of the studs. Wider 38 × 140 mm (2 × 6 in. nominal) or 38 × 184 (2 × 8 in.) studs can also be used to provide space for more batt insulation. The studs are attached to horizontal top and bottom 38 mm (2 in. nominal) wall plates that are the same width as the studs. If a concrete topping is used on a floor, it is recommended
