Tradical Hemcrete

Tradical® Hemcrete® is a blend of a lime based binder and the woody core of the hemp plant (shiv) and is growing into an established walling material for highly thermally efficient walls. Tradical® Hemcrete® has the following advantages over traditional building materials: * Absorbs CO2 in its manufacture and so has a negative embodied CO2. For a typical wall section Tradical® Hemcrete® will have an eCO2 of 130kg CO2/m2 less than traditional brick and block. * Is made from UK grown hemp – by being crop based it is a truly renewable material * Is highly insulating resulting in thin walls with a very low U value ideal for meeting the higher levels of the Code for Sustainable Homes and BREEAM. * Unlike other insulators Tradical® Hemcrete® has thermal inertia similar to thermal mass so houses built of Tradical® Hemcrete® change temperature very slowly reducing heating loads below lighter weight buildings with the same U value. * Is vapour permeable and when used with Baumit lime based renders and plasters creates a breathable walling system for healthy living.
