List four factors that will affect the design of the exterior wall studs
-Structural requirements
-Finish materials
-Wall sheathing type
-Thermal insulation requirements
Why is it not a good idea to leave concealed spaces in the wall frame?
Because it requires insulating before sheathing is applied
What are two purposes of an L-shaped corner stud?
To provide backing for wall finishes and a nailing base for intersecting walls

400mm o.c (16”) for standard walls
Describe an easy method for measuring the stud, cripple and jack lengths for a door or window opening in a wall.

What size of gap is left in the double top plat of an exterior wall to allow the double top plate of an interior wall to intersect it?
width of the interior wall plate plus 1/4” either side of the layout position
Why should the sheathing overlap the window openings?
provide strength at the corners of openings; also allows for increased spans of the lintels if structural sheathing is being applied
How are joins in the vapour barrier made vapour-tight?
4” overlap and tape
