UK Hempcrete is a UK construction company specializing in the use of hempcrete, or “hemp-lime”, and other natural building materials. We provide a complete range of services for home owners, builders and architects who want to build with these “deep-green” construction materials.
A relatively new composite material made from wet-mixing hemp shiv with a lime binder, hempcrete provides a natural, vapour-permeable, airtight insulation material which also has thermal mass, giving it a uniquely effective thermal performance. Using hempcrete in your building creates healthy (chemical-free and damp-free) indoor environments. It is a “better-than-zero-carbon material”, locking away more atmospheric carbon for the lifetime of the building than was emitted during its construction.
In new build, hempcrete is usually used to form walls, in combination with a timber structural frame, but it can also be used to create an insulating floor slab or roof insulation, allowing the entire thermal envelope of the building to be formed from hempcrete.
Because it is vapour permeable and has the ability to form itself around any shape before setting and supporting its own weight, hempcrete is the ideal material for upgrading the thermal performance of older traditional or historic buildings. It is particularly suitable for repairing timber frame infill panels, or adding insulation to solid masonry walls, and works in harmony with the original building fabric in traditional buildings to prevent moisture from becoming trapped in the wall.
