Cast-in-situ hempcrete forms a continuous mass, redu-
cing thermal bridging.
With hempcrete cast as a continuous mass, it is quite straightforward to design out cold
bridging in a hempcrete building, compared with a building whose walls are constructed
from a build-up of different materials. The most challenging area in which to avoid cold
bridges is the insulation of the plinth at the foot of the hempcrete wall.
Airtightness
Airtightness is an important consideration in the construction of buildings to a modern
standard. The increasing emphasis on the conservation of energy has led to a focus on
