Hempcrete: 'Better than carbon negative and ultra low fuel bills'

 

At a thickness of 350mm hempcrete achieves an insulation u-value of 0.17 W/m2K and a thermal mass capable of maintaining an internal ambient temperature of 14ºc (56ºf) irrespective of external temperature.

 

Embodying more carbon than it takes to produce, and actively continuing to capture carbon over it's life time as 'it breathes', a hempcrete house is an exceptional ecological and economical building solution, requiring minimal heating, cooling and ventilation whilst achieving ultra low running costs.
