“We shape our buildings; thereafter they shape us…” said Winston Churchill (1874-1965), who died 50 years ago this this week. This oft-quoted comment on architecture resonates today as much it ever did. With the emphasis today on building (and upgrading our existing buildings) to meet standards of energy performance – in both construction and use […]
NATURAL BUILDING LIVE, NEC 9-12 October 2014 Hempcrete, along with other natural building materials, proved a major attraction at the Grand Designs Live Show at the NEC, Birmingham in October 2014. Hemp-LimeConstruct has been involved with the show for the last 4 years, helping to promote hempcrete by demonstrating it, along with other natural building […]
What can I expect from hempcrete in terms of its thermal performance? The thermal properties of hempcrete are extraordinary. It provides insulation because of pockets of air trapped within the material; both in the spaces between particles of hemp shiv, and in microscopic pores in the hemp shiv itself. Compared to synthetic insulation materials, hempcrete […]
Hempcrete is completely natural and free from synthetic, fossil fuel based materials. Because hempcrete is naturally fire-retardant and pest-resistant (nothing eats lime!) there is no need to add chemicals to ensure its performance in these areas (as is usually the case with lightweight synthetic insulation materials). Chemicals added to conventional insulation materials often contain Volatile […]
Hempcrete is carbon negative Hempcrete is a “carbon-negative” or ”better-than-zero-carbon” material; more carbon is taken out of the atmosphere by the growth of the hemp plant than is emitted as a result of its production and application on site. Various estimates for the amount of carbon sequestered have been put forward, and of course this […]
So what exactly can you can use hempcrete for? In new-build, hempcrete is most commonly used to make walls, but can also be used to form floor slabs, ceilings, and roof insulation. Hempcrete walls In contrast to conventional insulation materials (which tend to be installed in a cavity within the wall, or added to wall […]
