Hemp Lime
Hemp Lime is a non-load-bearing building material composed of hemp shive, lime binder, and water that is non-toxic and devoid of volatile organic compounds (VOCs). A lightweight substance, it weighs approximately one-eighth as much as concrete. It is possible to create walls, floors, and roofs with hemp lime. Hemp lime allows architects and house owners architectural freedom.
Hemp Shives & Lime = Hemp Lime
Areas of application of Hemp Lime
Hemp Shives are ultra-light woody inner core of hemp stalk. They are present in the stem of annual fibrous plant. Hemp shives are especially light and structure-forming. Hemp shives for structural use are not yet a construction material! The building material is created on the construction site.

The base for a comfortable interior environment, walls constructed of hemp-lime fulfill strict requirements for thermal insulation, latent heat protection, openness to diffusion, and moisture management.
A healthy indoor environment is built on the management of ions and moisture.
Due to the high insulation properties, the hemp stone does not require any additional insulation
The Benefits of Home built with Hemp Lime
Hemp lime provides high levels of thermal and acoustic insulation. It also manages internal relative humidity and temperature fluctuations "via hygroscopic material behavior, leading to healthier building environments and delivering effective thermal mass." The building envelope is permeable to vapor, enabling moisture to escape and avoiding the possibility of condensation on inside surfaces.

Carbon from renewable biomass should be stored throughout the lifetime of the construction material. Develop a vapor-permeable building envelope that promotes healthy indoor air quality.
The Relationship Between Hemp Lime and the Environment
C02 is absorbed by hemp lime, which is better than zero carbon.
Hemp lime have a low environmental effect, and its potential for carbon sequestration and storage is a key advantage of the material. The hemp plant takes CO2 from the environment during photosynthesis, turning carbon into biomass and exhaling oxygen. When hemp is utilized in construction, the carbon it contains is sequestered throughout the lifetime of the building. Hence, the use of hemp in building construction might be superior to zero carbon, also known as carbon negative. 1 m3 of Hemp lime can store 108 kg of carbon dioxide.
