These blocks are manufactured by IsoHemp from hemp shiv and natural lime in a factory‑controlled process, forming a 100% natural masonry unit without petrochemical additives. They are designed for new construction, insulation of existing walls, partitioning and retrofits, offering a flexible solution across dwelling types. The inherent hygrothermal properties of the hemp–lime matrix improve durability, reduce maintenance and help regulate indoor humidity and temperature. There are a variety of complimentary render and plaster finishes like clay and lime that support natural breathable systems, contributing to healthier interiors. Available throughout Europe via IsoHemp’s distribution networks. IsoHemp emphasises its blocks as insulating and all natural building materials targeting low‑carbon construction. The main limitation is in public transparency on health-hazard disclosure, sourcing traceability, explicit end-of-life protocols.
