This webinar is designed to introduce participants to the materials and techniques required to use hempcrete as a building insulation material. Based on the book, Essential Hempcrete Construction, we will examine the material properties and specifications for hemp and for a variety of binders, and look at sourcing options for these materials. Mix ratios, forming systems and material placement will also be covered, including the use of hempcrete as sub-slab, wall and roof insulation. We’ll also cover the material costs and labour inputs for using hempcrete, as well as the equipment required to mix and place. Finishes for hempcrete walls will also be covered. Finally, the webinar will examine the building science implications of using hempcrete, including thermal performance, moisture performance and air-tightness.
