Insulation made from hemp may be the next big thing for eco-friendly home builders. Researchers at Bath University believe hemp could be used to build environmentally friendly homes of the future. A consortium, led by the BRE Centre for Innovative Construction Materials, which is based at the university, has constructed a small building out of hemp-lime to test its properties as a building material.
Called the 'HemPod', the one-storey building incorporates highly insulating walls made from the chopped woody core, or shiv, of the industrial hemp plant mixed with a lime-based binder.
The hemp shiv traps air in the walls, and the hemp is porous, which provides insulation. The lime-based binder sticks together and protects the hemp and makes the building material fire resistant.
The industrial hemp plant takes in CO2 as it grows, and the lime render also absorbs the gas, giving the building a low-carbon footprint.
The project is sponsored by the Department for Environment, Food and Rural Affairs.
