mean an increase in the distance between the two studs, then an additional vertical timber
should instead be used to create the edge of the door opening, tied back to the nearest stud
with noggins as required to hold it securely in place.
The timbers for door framework are typically doubled up at the sides as well as for the
lintel, since the sides must be solid enough to hold the door frame in place with no move-
ment, even under the force of the door being slammed.
Noggins
Noggins are horizontal timbers connecting and supporting adjacent studs or joists. A nor-
mal timber-frame building has noggins in the walls to provide extra stiffness to the frame,
but in a hempcrete building, the hempcrete provides this function once it has set around
the studs. In a frame for hempcrete, horizontal timbers, including noggins, should be kept
to a minimum, to make placing the hempcrete easier. However, noggins may be required
for several reasons:
to give extra support to reinforced studs that carry extra load in order to prevent them
bending (see photo opposite, top)
where permanent shuttering is used, to provide horizontal fixings for the joins in the
board
between floor or ceiling joists to stiffen that part of the structure.
