Hempcrete is a building material with excellent properties. It's made from lime
and hemp shivs (a waste product from hemp fiber growing); it can be used for
walls, floors, and for roof insulation; it's breathable, absorbing and emitting
moisture to regulate internal humidity and avoid trapped moisture and mould
growth; it provides excellent acoustic and thermal insulation and thermal mass;
it's lightweight and reduces construction costs; and it's environmentally
friendly—it locks up CO2 for the life of the building, and the hemp doesn't
require agrochemicals or insecticides in its cultivation. This book is a
detailed practical manual for professionals and self-builders, detailing how to
source and make hempcrete
