- If existing walls, which the wall post is to be placed to, are not perpendicular or are bulging, the wall post may be displaced inwards. The difference of such displacement is to be taken into account when calculating the pitch size.- If partition walls are erected between two wall posts, the sizes measured for the length of the foot and head runners should be used for the calculation of the pitch size about 20 mm smaller to avoid pressing of the framework of the wall when erecting it.
- If sound insulation is required for the partition wall to be built, all joints between the wall and the wall posts, between the ceiling and the head runner, as well as between the floor and the foot runner are to be sealed with sound-insulating material.
- Sound bridges must be avoided, otherwise it would mean a waste of the finance and material employed.
- If doors are to be included in the partition wall to be built, the door posts, door fixing posts, door lintel transom and tail posts with the respective sizes are to be scribed in the same manner as the posts (see page 17 hereof).
- If partition walls with corner posts are required, the meeting of the walls and the existing building clearance are decisive for the wall to be erected first.
- If partition walls are erected at right angles to the wooden beam ceiling, the distances of the holes for fixing the runners depend on the distances of the wooden beams.
- If foot runners are interrupted by door opening, the foot runner is to be cut only at the place of mounting so that it can be used, if in alignment, for scribing on the floor (of alignment)!
- For stabilizing the door opening on the floor, the foot runner can be held by a metal square to be additionally mounted. The leg of the square to be screwed to the floor must not be longer than the thickness of jamb lining to be provided! Long nails (4.2/100) may be used for fixing the leg of the square to the cross-grained wood of the runner.
- If partition walls are erected between solid ceilings, the runners are to be placed according to the alignment lines and the holes in the runners for fixing to ceiling and floor are to be scribed. The size is to be measured from the joining side of the runner to the centre of the hole on that side of the runner which will contact the floor or the ceiling when the partition wall is erected. This is necessary to enable dowels to be inserted or holes for straddling dowels to be bored and dowels to be driven in for fixing the runners prior to the erection.
