Builders Are Using Hemp Instead of Concrete & It Could Save The Environment

Anthony from Art du Chanvre has built over 45 houses using hempcrete as a natural and sustainable insulation material…

Awaken

Hempcrete is made with a mix of hemp hurd (fibre), hydraulic lime (binder), and water. Hempcrete is not load-bearing, but it does provide insulation, thermal mass, and it regulates temperature and humidity. The R-value of hempcrete is R-2.1 per inch. Some other advantages of hempcrete is that it resists fire, mould, and vermin, and it eliminates the need for a vapour barrier and drywall (gypsum). Instead, you protect the hempcrete with natural lime plasters on the inside and on the outside of the building. Using hemp is a sustainable building material because it is carbon negative (it stocks more carbon in the fibre of the plant than is used to grow, harvest, and process it).
