  1. Competency: 206.00Draw wall sections and details Objective: 206.03 Apply concepts of wood frame wall construction.

  2. Wood Frame Wall ConstructionMaterials • Wood studs should • Be straight • Have good stiffness • #2 grade or better • Moisture content of 15-19%

  3. Wood Frame Wall ConstructionMaterials • 2x4 and 2x6 lumber are most popular sizes for wall construction • 2x6 materials can be used for exterior walls for additional insulation thickness • 2x4 materials used for most interior walls • 2x6 and 2x8 materials used to allow plumbing to pass through wall

  4. Wood Frame Wall ConstructionMaterials

  5. Wood Frame Wall ConstructionComponents • Sole Plate/Bottom Plate • Holds studs together in a wall unit • Anchors wall to subfloor • Wall studs • Spaced 16” or 24” O.C. • Length based on ceiling height • Top plate • Ties intersecting walls together • Provides additional strength between studs where ceiling joists/rafters do not bear directly above the stud

  6. Wood Frame Wall ConstructionComponents • Headers • Size depends on its span and loading • Carries load of the roof where studs have been removed from the wall to create an opening

  7. Wood Frame Wall ConstructionComponents • Solid headers • Fill the space above the opening • Header formed by turning two units of framing lumber on edge with a ½” spacer between the members • For 2x4 stud wall a 3-½” thick unit

  8. Wood Frame Wall ConstructionComponents • Solid headers • Studs are not full length • Fill the space above the header • Headers are supported by trimmers or jack studs

  9. Wood Frame Wall ConstructionComponents • Corner Bracing • Plywood, OSB, or similar material may be used in place of the let-in brace • Diagonal metal straps may be used

  10. Wood Frame Wall ConstructionExterior Finishing • Wall sheathing • Typically ½” thick • May be a structural material and/or an insulating material • Often applied to frame wall prior to wall being raised from the subfloor • Often applied to frame wall prior to wall being raised from the subfloor

  11. Wood Frame Wall ConstructionExterior Finishing • Wall ties • Masonry wall is not a load bearing wall • Frame wall carries the load of the structure • Ties are bent to fit between mortar joints • Corrugated metal ties • Placed 16” O.C. vertically • Placed 32” O.C. horizontally
