Hempcrete is a natural, energy efficient building and insulating product.Carmeuse has developed limes to satisfy the needs of all designers, craftsmen and home-owners for their hemp-building construction. 


Bio-based economies are becoming part of our daily live. The search for a carbon negative footprint building & insulation material is on-going, and hempbuilding is offering a natural sustainable solution for each of us. Hempbuilding is become the reference bio-product used for insulation & healthy inside climate, due to its ability for moisture regulation.


Hemp absorbs carbon dioxide as the plant grows. As a result, the use of hemp and lime when building helps to reduce the carbon footprint of buildings, and can even lead to a negative footprint for the entire construction. Hemp-building results in low-energy houses, because hemp can absorb and hold heat (thermal mass) during sunny periods, when heat is not needed for internal living or work spaces. That heat is released when required, such as during overcast periods or at night, to provide substantial energy and cost savings. Buildings with hemp have high vapor permeability, which facilitates the through-transfer of humidity and thus avoids condensation and trapped moisture within the building. This improves the building's air quality and controls humidity, whilst reducing the risk of the growth of molds and fungi that may affect occupants’ health.
