Hemcrete: Carbon negative insulation for timber frame buildings

Hemcrete can be used with any timber, concrete or steel framed building, Hemcrete replaces all insulation within the walls and can even be used as insulation within roofs and floors.

Installing Hemcrete requires the same skills and knowledge that are used for shuttering concrete; coupled with our experience of energy efficient buildings Denstone construction is ideally suited for this specialist work.

Hemcrete® is an established walling material for carbon negative highly thermally efficient walls which 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 ideal for meeting the higher levels of the Code for Sustainable Homes.
• Unlike other insulators Hemcrete® also has thermal inertia similar to thermal mass and so houses built of Hemcrete® change temperature very slowly reducing heating loads significantly below lighter weight buildings with the same U value.
• Hemcrete® is vapour permeable and when used with Baumit lime based renders and plasters creates a breathable walling system for healthy living.
