Hemcrete is tried and tested walling material for carbon negative, highly thermally efficient walls.

Hemcrete has the following advantages over traditional building materials:

• Hemcrete absorbs CO2 in its manufacture and so has a negative embodied CO2. For a typical wall section Hemcrete will have an eCO2 of 130kg CO2/m2 less than traditional brick and block

• Hemcrete is made from renewable UK grown hemp based materials

• Hemcrete is highly insulating resulting in thin walls with a very low U value

• Unlike other insulators Hemcrete also has thermal mass (or thermal inertia) and so houses built of Hemcrete change temperature very slowly reducing heating loads significantly below those lighter weight buildings with the same U value.

• Hemcrete is breathable and vapour permeable and when used with Baumit lime based renders and plasters creates a breathable walling system for healthy living.
