Insulating Traditional Buildings Using Hempcrete

Hempcrete, made by mixing hemp shiv (the woody stem of the industrial hemp plant) together with a binder, was first developed in France as a method of adding thermal performance to medieval timber frame buildings, whilst allowing the historic building fabric to continue working in the way it was intended to.

Our hempcrete journey began in the classroom, where we uncovered the wonders of this material – from insulation to thermal mass and its incredible vapour-permeable qualities.

Our pilot cohort got a chance to experience the two most common ways of installing Hempcrete in traditional buildings: wet-mixed cast on site and pre-cast blocks. In our practical training session we used pre-cast blocks for internal wall insulation (IWI) and wet-mixed cast Hempcrete externally as external wall insulation (EWI).
