Rafters bearing on the wall plate and fixed down from
above with long screws, to avoid fixings coming into con-
tact with the hempcrete.
In the case of a large residential or commercial-scale building in which a steel frame is
used, an entire stainless-steel structural frame would of course be extremely expensive to
fabricate. It is therefore advisable that the steel frame sits independently inside the walls
of the building, with as little steel as possible interacting with the hempcrete. This might
mean, for example, connecting the hempcrete stud frame to the timber rafters of the roof
(as shown in Figure 19). Where it is necessary for the hempcrete to come into contact with
the steel frame, sections of steel should be supplied pre-painted with a protective paint, and
should also be repainted around the screws, bolts and other fixings once these are in place.
