Hempcrete or hemplime is a biocomposite material, a mixture of hemp hurds (shives) and lime,[1] sand, or pozzolans, which is used as a material for construction and insulation.[2] It is marketed under names like Hempcrete, Canobiote, Canosmose, Isochanvre, and IsoHemp.[3] 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.[3] The result is a lightweight insulating material ideal for most climates as it combines insulation and thermal mass.
