France: Heidelberg Materials has launched a new range of its Socli lime product that contains hemp. The product is available in two binder and two coating formulations that combine natural hydraulic lime and plant fibres. Formulated for hempcrete bio-based concrete applications, on vertical walls or for insulating intermediate floors, its high lime content increases durability, according to the producer.
Heidelberg Materials says that the Socli lime range is especially suited to the restoration of historic buildings, as it guarantees breathable walls and healthy indoor air, and prevents mould, while providing thermal and acoustic insulation. The absence of cement further increases hygrometric regulation and thermal insulation.
