Alex's sister describes hempcrete as a hemp-based building material with a structure she compares to concrete. She favors it for thermal insulation and what she regards as environmental advantages. Hemp is grown as a crop and has uses beyond construction. Jute is a different fibre, and she gives a separate example of using it to cover concrete and keep it warm in cold weather. These are distinct uses of plant materials, with hemp in the building material and jute serving as a protective covering.
