provides additional natural light to
the stairwell. The space between the
door posts between the door head
and the window sill was filled with
tightly packed straw contained by
wire netting. This was then rendered
and blended into the walls at either
side of the door (see Figure 5.4).
Install temporary braces and
spacers to door bucks
When installing door posts and door
bucks it is important to fit braces
and spacers between the posts to
prevent the door posts being bowed
in or twisted out of shape as the
bales are laid. As a general guide, if
the buck is greater than one metre
high it will be necessary to fit the
temporary spacer between the stiles
to prevent the stiles bowing inward
as the bales are laid. If in doubt, fit
additional spacers. There is nothing
more frustrating that having the
wall complete with the first coat of
render on, only to find that the
window will not fit in the buck
because it has been bowed in by over
exuberant bale layers. Rather than to
fix a single brace from one corner to
the other it will be more effective if
one brace is fixed from the top of one
stile to the centre of the other stile.
Then fix a brace from the bottom of
the first stile to the centre of the
second stile so that the braces form a
'V', fixed horizontally to the face of
the door posts or door buck (see
Figure 5.5).
