IsoHemp hempcrete blocks are great for glued, non-load-bearing masonry for building healthy, natural insulation and partition walls. It is very versatile and recommended by professionals for both new builds and renovations, whether its single-family projects, community buildings and commercial buildings.

Energy saving

Hempcrete blocks are the answer to a number of technical challenges

The IsoHemp hempcrete blocks are particularly suitable for residention constructions, for adding a second wall to existing walls on the inside or from the outside, as well as industrial partitioning and for apartments.

  • It allows you to achieve low-energy, very low-energy and passive house standards.
  • They are technically recognised and has all necessary certifications as per the current European regulations

    5 major hempcrete block features for your projects


    Thermal regulation

    Hempcrete blocks naturally regulate the temperature of the building thanks to their excellent ability to diffuse accumulated heat. This insulating blocks with high inertia protects from :

    • cold in winter, keeping the heat inside the house
    • hot in summer, avoiding overheating of the living space.

    As a true thermal buffer, the blocks keep the indoor temperature constant and significantly reduce the impact changes in heat between day and night.

    Humidity regulation

    Thanks to its high permeability to water vapour, the hempcrete blocks act as a water buffer and offer a constant and healthy indoor climate for the occupants. The relative humidity level is thus stabilised (from 50% to 55%). They can be used for :

    • Renovation and insulation of old buildings, old brick or damp walls
    • Interior renovation to insulate walls that wooden floor boards rest on; to prevent any condensation issues in the transition areas between materials to guarantee the excellent conservation of the building
    • Humidity regulation in commercial projects where variations in humidity are critical: archive rooms, museums, sports halls, swimming pools ...

      Acoustic Insulation

      Whether IsoHemp hempcrete blocks are used for interior walls or partitions, external and ambient noise will be significantly reduced. In terms of sound insulation, hempcrete blocks acts as a real sound barrier and can lessen the majority of acoustic waves, thus protecting you from noise pollution.

      Protection and fire resistance 

      IsoHemp hempcrete blocks meet all current standards and provide a simple and effective solution to your construction site, whether for industrial or community buildings (nurseries, schools ...) or residential homes. With an excellent reaction to fire (class A1 for the coated block), it offers up to more than 2h fire resistance depending on the finish and the width of the block used.

      Health and environmental qualities

      The hempcrete block meets the strictest requirements of sustainable development: it is manufactured using a very energy-efficient process, using 100% natural materials (limestone and hemp) that are sourced locally. Building or renovating your home with hempcrete blocks can sustainably save more than 2 tons of CO2. That's one way of improving your carbon footprint 

      These are all the uses for hempcrete blocks

      IsoHemp hempcrete blocks can be used as a second wall, filling masonry or for partitioning. Both in new builds and renovation, it provides solutions for all circumstances :

      Interior insulation New builds Interior masonry Exterior insulation 

      Extensions Floor insulation Flat roof insulation

      Range, finishing options and building with hempcrete blocks

      Range : 8 different types of width and 2 types of technical blocks (cf. fact sheets) 

      Finishing options : For a smooth, white, economical surface ready to be painted chose the natural IsoHemp PCS coating for indoors (+ lien vers Enduits naturels PCS). Limestone and clay plasters are also perfectly suitable. For outside, mineral plaster and all types of cladding can be applied directly to the blocks. Double masonry (with bricks, country stone, etc.) is possible using a mechanical tie.


      IsoHemp hempcrete blocks are laid like in traditional masonry in running joints. They are bonded in 3mm thin joints with IsoHemp adhesive mortar, which is specially adapted for quick installation. Large but light, they allow easy on-site application.
