Hemp blocks:
a response to many
technical challenges.
The IsoHemp hemp block is particularly suited to the construction of residential houses, the internal or external lining of existing walls, as well as the industrial and apartment partitioning.
- It makes it possible to achieve low-energy, very low-energy, and passive standards.
- It has a technical approval and benefits from all the necessary certifications according to the current European standards.
5 major assets of the hemp block for your project.
Thermal regulation.
The hemp block naturally regulates the building’s temperature thanks to its excellent capacity to diffuse accumulated heat. This insulating block with high thermal inertia protects:
- against cold in winter by retaining heat longer inside the home
- against heat in summer by preventing the building from overheating.
A true thermal buffer, it maintains a constant indoor temperature and significantly reduces the impact of temperature variations between day and night.
Humidity control.
Thanks to its high permeability to water vapour, the hemp block acts as a moisture buffer and provides a constant, healthy indoor climate for the building’s occupants. The relative humidity is thus stabilised (between 50% and 55%).
Its uses:
- Renovation and insulation of old buildings, old brick or damp walls
- Interior renovation to insulate walls into which wooden floors are embedded, avoiding any condensation problems between material interfaces and ensuring excellent preservation of the existing building
- Humidity regulation in tertiary projects where humidity levels vary significantly: archive rooms, museums, sports halls, swimming pools...
Acoustic insulation.
Whether IsoHemp hemp blocks are used for your walls or interior partitions, outdoor and ambient noises will be significantly reduced. In terms of sound insulation, the hemp block acts like a real sound trap, absorbing the majority of acoustic waves and thus protecting you from noise pollution.
Fire resistance.
The IsoHemp hemp block meets current standards and provides a simple and effective solution for your construction challenges, whether for industrial or collective buildings (nurseries, schools...) or for homes. With excellent fire reaction (class B-s1 d0), it offers more than 2 hours of fire resistance depending on the finish and thickness of the block used.
100% natural solution.
The hemp block meets the strictest sustainability requirements: it is manufactured through a very low-energy process, from 100% natural bio-based materials (lime and hemp) sourced from local supply chains. It has a very positive carbon balance, as a pallet of IsoHemp hemp blocks stores 100 kg of CO₂.
