Hempcrete or
hemplime is
biocomposite material, a mixture of hemp hurds (
shives) and
lime,
sand, or
pozzolans, which is used as a material for construction and
insulation. It is marketed under names like Hempcrete, Canobiote, Canosmose, Isochanvre and IsoHemp. Hempcrete is easier to work with than traditional lime mixes and acts as an insulator and moisture regulator. It lacks the
brittleness of
concrete and consequently does not need
expansion joints. The result is a lightweight insulating material ideal for most climates as it combines insulation and
thermal mass.
