Uses for Hempcrete
Newbuild: Using shuttering, Hempcrete can be cast in situ to create walls of various thicknesses and shapes. Hempcrete is self-supporting, but not a load bearing product so it is usually formed around a softwood timber frame. Hempcrete can be used in the construction of floors and roofs, adding a breathable, insulated layer.
Restoration projects: In old buildings, Hempcrete can be used to replace damaged or missing infill. It can also be used internally to add an insulated but breathable render to stone walls.
