When the wall appears to be vertical, check the other end of the wall. If there is a
variance in the readings, and the level is not faulty, you can set the wall as an average
between the two readings. Once the wall is vertical fix the brace to all the studs and the
top plate. If the external wall of the house is a timber framed wall, set the position of the
two end walls and then fix a string line along the outside of the wall as a guide to the
positions of the intermediate wall, as the outside wall needs to be straight.
Removing a bow in the top wall plate between adjoining walls
Once all the wall braces are fixed, look along the top of the walls to see if any of the
individual walls are bowed. The amount of bow that is acceptable at the top of the wall
will depend on the wall lining and personal taste. If the wall needs to be straightened do
so with the push brace as previously discussed, and then fix a temporary brace from the
top of one of the studs at the centre of the bow to the floor or the bottom of another wall.
A good rule of thumb is 'if in doubt, fix it'.
Cutting and installing special length noggings
Now that all the walls are fixed in their permanent position, the special length noggings
can be cut and installed. At the wall junctions you will need to install two noggings or
blocks in the wall running across the end of the adjoining wall. The stud of the adjoining
wall is to then be fixed to these short noggings (see Figure 6.19).

Noggings for walls with ceramic wall tiles
If you are fitting ceramic tiles in the shower recess you will need to fit additional noggings
between the studs in this area. If you fit a nogging every 400 mm up the stud this will
provide a good stable base for the tiles. Once the shower base is fitted a nogging will be
fitted at the shower base approximately 5 mm above the lip of the shower.
It is also advisable to fit noggings to support toilet roll holders, towel rails and any
mirrors or heavy pictures that are to be hung. Record the position of these noggings as
inevitably you will have difficulty remembering where they are. The ideal position for a
