Hemplime mix

Our different types of hemplime mixtures are specifically produced based on use, guaranteeing an optimal functioning and installation. Thanks to our products, your renovated house will not only be equipped with an efficient insulation, it will also have a humidity regulating, heat buffering and sound insulating layer that will take the comfort of your house to the next level.


A finished insulated wall in one day.

We have already dried the HIAB-mix in advance in order to offer you a ready-to-use wall. This dry insulation material is placed between the wall, floor or ceiling that has to be insulated and the final shuttering. As shuttering, you can use any solid permeable plating, however we recommend Extreem Green plating, which guarantees to be permeable, very strong, ecological and fire-resistant. Besides, you can immediately put the finish of your choice on these panels (painting, wallpapering, plastering,…).

Canadry is used as a non-carrying insulation in walls, floors and ceilings. Canadry is simply attached in the desired thickness, pressed and finished with the permeable plating.

With Canadry you can install the internal insulation yourself in a very simple and fast way and benefit from all the advantages of a house which is insulated with lime-hemp without having to wait for it to dry out. Our Canadry is delivered in big-bags of 1m ³ and in bags of 70l.

    your ready-made hemplime mixture

    We mix the lime, hemp, minerals and water in advance for you to make sure that you can get started immediately with the insulation of your walls. This wet insulation is placed in a temporary shuttering by pressing it slightly and in a equal way. To ensure that the product gets attached tot he wall, we recommend to first treat the wall in question with a lime-water mixture and to use spaced (at regular distance) wall plugs.

    HIABMIX-wall is used as a non-carrying insulation for walls to realize a traditional lime-hemp insulated wall. The HIABMIX is delivered in big-bags of 1m ³ or in bulk. In good conditions, the HIABMIX-WALL can be used within a week.

    A floor without concrete? It’s possible thanks to HIABMIX-floor

    In case you don’t have a concrete slab in your new or to be renovated house yet, our HIABMIX-floor is a genuine, healthy alternative. De HIAB-mix floor is placed on a layer of shells which absorbs the upward humidity. DE HIABMIX-floor can be finished with a lime screed. The installation of an underfloor heating is perfectly possible.

    We mix the lime, hemp, minerals and water in advance for you. De HIABMIX is delivered in big-bags of 1m ³ or in bulk. The specific composition of this mixture guarantees an accelerated hardening of the floor to allow you to continue the works quickly. The HIABMIX-FLOOR can be used within 24 hours


    In the roof, you get the most out of your lime-hemp insulation

    Thanks to the natural heat buffering of lime-hemp, this insulation is the ideal material to install in a flat roof as well as in a sloping roof. In addition to a good insulation in winter,  you will have a cold fresh room in summer. In the case of an existing roof, you have to remove the roofing to be able to pour the HEMPMIX-roof in pre-installed nets or shuttering. In a day or two you will have a fully insulated roof which is prepared for cold winters and hot summers.

    Wij mengen voor u de kalk, hennep, mineralen en het water op voorhand. De HIABMIX wordt geleverd in bigbags van 1m³ of in bulk. De HIABMIX-ROOF kan onder goede omstandigheden gedurende een week verwerkt worden.

    You can also opt for a completely new roof by using our HIAB-roof panels.

    We deliver custom-made, carrying and insulating panels which offer you all the benefits of hemplime and secondly, which can be mounted quickly and easily.

    The Hemp in a Box prefabricated panels are the solution for those who want to build quickly and efficiently with hemplime.

    • The wooden frame, which is made with CNC steering, is the supporting structure and ensures the strength of the walls.
    • The lime-hemp mixture is placed in the wooden frame according to the indicated specifications. This results in a wind-proof, solid insulated wall. If necessary, an additional insulation is placed, as well as wait tubes or finished plating.
    • Thanks to the exceptional characteristics of lime-hemp, the wall is permeable, insulating and humidity regulating.
    • In just a few days, these panels are installed on the site by a specialized installer thereby saving on time and workforce.
    • After installation, you can immediately start with the finishing of the panels .

    How do we work?

    • Based on the architectural and stability plans, our team makes detailed drawings of the entire construction project and we split up the building into panels.
    • These panels are assembled in our workshop and filled with the hemplime insulation.
    • If desired, we include wait tubes and plating for the finishing on the walls.
    • The panels are delivered on the site, where a contractor will build a complete structural work, including the insulation, in just a matter of days.


    For houses, we deliver 30 cm thick standard panels, designed to meet the strictest insulation standards. To reduce the work afterwards to a minimum, we can already pre-install wait tubes and finishing plates. The inside of these panels can be finished with various vapor permeable materials and techniques. Although practically every type of outside facade is possible, we recommend to finish the exterior with a vapor permeable product (brick, plaster, wood).

    HIAB-home V1

    Panels made of lime-hemp and wood wool

    HIAB-home V2

    Panels made of dry lime-hemp


    For the roof we make entire panels so that your roof can be completely realized in 1 day.


    Our way of working for panels for professional applications (storage, education, leisure,..) is similar to the one that we use for HIABHOME panels. The construction and the dimensions of the panels can vary depending on the specific implementation and requirements of the architect. Do not hesitate to contact us to go through the possibilities together.

    EXTREME GREEN plating:

    Finished panels on a higher level

    This plating is the ideal finish for your walls for both inside and outside, and vertically as well as horizontally. The Extremegreen plate, consisting of Magnesium oxide, glass fiber and recycled wood fibers guarantees zero toxic emission and has a low-energy production process (up to 50% less than similar products)

    The Extremegreen plating is a high-quality alternative for plywood, OSB, plaster and cement plates.

    These Magnesium oxide panels have the following advantages:

    1. Fire-resistant: The plates have been tested in the UK and have a certificate for fire resistance of 1 hour.
    2. Water resistant: The Extremely Green plates can be exposed to water for a long time without loss of structural integrity. Nevertheless, we recommend using a finishing layer on the outside.
    3. Anti-fungal
    4. Impact resistant: the panel is extremely solid and can resist a big impact without any damage
    5. High capacity: the material can be mounted directly on the plate (with screws)
    6. No emission of toxic substances (does not contain formaldehyde, fly ash,..)
    7. Pest-resistant
    8. Vapor permeable
    9. Immediate finishing on the plating (painting, plastering,…) which allows to reduce the costs with 50 % compared to other materials.

    The combination of HIAB panels or HIAB Mix with Extremegreen plating makes an optimal combination for a durable insulating wall, which reduces the finishing cost to a minimum without sacrificing quality.

    We deliver these panels in thicknesses of 6,9 or 12mm.

  • Shells

    A layer of shells is, contrary to sand, not capillary. This means that the water is not absorbed, but that a natural barrier is formed between the groundwater and the ground floor, which prevents upward humidity. The top layer of shells is completely dry and the evaporation of groundwater is significantly reduced.

    The combination of shells and the hiabmix-floor mixture is the ideal soil structure for a stable soil layer. Both purify the climate in your home and interact, thereby generating an ideal humidity.

    The installation of shells is fast and easy. We deliver these shells in big bags or in bulk.
