Wall Framing

  • Wood panel wall sheathing provides significant resistance to lateral loads from high winds and earthquakes. In areas with a risk of high winds and earthquake loads, thicker sheathing, closer nailing patterns and the provision of “braced panels” may be required to strengthen walls.
  • Select appropriate sheathing thickness and nailing patterns to provide adequate resistance to lateral loads.
  • Select a wall arrangement that will accommodate the necessary amount of insulation for your climate zone.
  • Provide wall framing deep enough for the required insulation and locate pipes or ducts in interior walls

Wall framing used with platform construction

Lintels are the horizontal members placed over window, door and other openings to carry loads to the studs on either side of the opening (Figure 68).

They are usually constructed of at least two pieces of 38 mm (2 in. nominal) lumber, nailed together to form a single unit. Rigid insulation is commonly used as a spacer between the members to make the lintel the same thickness as the wall framing. The depth of a lintel is determined by the width of the opening and vertical loads supported. (See Tables 26 and 27 on pp. 291-293) For openings less than 3 m (10 ft.) wide, provide a full stud on each side of openings (Figure 68) and a jack stud on each side to support the lintel. For openings wider than 3 m (10 ft.), provide double jack studs on both sides in addition to the
full studs.
