1. Except as permitted in Sentences (2) and (3), all studs shall be placed at right angles to the wall face.
2. Studs on the flat are permitted to be used in gable ends of roofs that contain only unfinished space or in non-loadbearing interior walls within the limits described in Article 9.23.10.1.

   1. the studs are clad on not less than one side with plywood, OSB or waferboard sheathing fastened to the face of the studs with a structural adhesive, and
   2. the portion of the roof supported by the studs does not exceed 2.1 m in width.

1. Wall studs shall be continuous for the full storey height except at openings and shall not be spliced except by fingerjoining with a structural adhesive. (See Note A-9.23.10.4.(1).)

3. Single studs are permitted to be used on either side of openings
   1. in non-loadbearing interior walls not required to have fire-resistance ratings, provided the studs extend from the top wall plate to the bottom wall plate, or

      1. the opening is less than and within the required stud spacing, and
      2. no 2 such openings of full stud-space width are located in adjacent stud spaces. (See Note A-9.23.10.6.(3).)
