Hempstone
Masonry block made of hemp and lime
Hemp blocks are masonry and insulation in one. You set them in a load-bearing frame, for new builds and renovations.
What suits you?
Offcut take-back & building biology
Hemp shives and natural lime form the building material hempcrete.
Possible without an additional insulation layer, depending on wall thickness and requirements; buffers moisture; site offcuts taken back via RecyHemp.

Processing
Hemp bricks are not only very easy to work with when cutting and milling. The lightweight stones can be easily erected as partition walls, insulating exterior walls, interior insulation and acoustic walls. Hemp-limestone is always installed in a wooden or concrete skeleton. Hemp bricks are light, very good insulating bricks and do not bear loads.
Simply lay the hemp stone with the appropriate thin-bed mortar. To maintain diffusion openness, the base and finishing plaster must be breathable.
Building physics
Isohemp hemp blocks combine thermal insulation, sound protection and moisture buffering. They have fire classification B-s1,d0, insulate with λ = 0.071 W/mK and are vapour-permeable. Depending on wall thickness and requirements, no additional insulation layer is needed.
Production
For the production of hemp limestones, hemp hurds, the woody stalks of the hemp plant, lime and water are mixed and pressed in a cold air process and then dried.
