1. What is the composition of the IsoHemp hemp block?
IsoHemp hemp blocks are made from 80% hemp, 9% aerial lime, and 11% hydraulic lime. This natural mixture guarantees an ecological, high-performance, and environmentally friendly material. In addition to being an excellent thermal insulator, hemp allows for natural regulation of humidity and acoustics in buildings. IsoHemp hemp blocks are composed solely of sustainable materials sourced from local resources, thus ensuring a reduced carbon footprint and a positive environmental impact.
2. Is the IsoHemp hemp block healthy?
Yes, IsoHemp hemp blocks are entirely healthy. They are made from natural materials without toxic substances or chemicals. Whether you are building, renovating, or living in a house constructed with these blocks, you have nothing to worry about regarding your health. IsoHemp hemp blocks are not only ecological but also non-harmful to the occupants' health, contributing to a healthier living environment.
3. What are the available dimensions for IsoHemp hemp blocks?
IsoHemp hemp blocks are available in several thicknesses to adapt to different construction and renovation needs:
- Thicknesses: 7.5 cm, 9 cm, 12 cm, 15 cm, 20 cm, 25 cm, 30 cm, 36 cm.
- Length: 60 cm.
- Height: 30 cm (except for the 36 cm blocks, which are 20 cm high to facilitate handling and installation).
These dimensional variations allow for great flexibility for any type of project, whether it's for insulating exterior walls, interior walls, or even floors.
4. What is the thermal resistance of IsoHemp hemp blocks?
The thermal resistance of IsoHemp hemp blocks is one of their main assets. It varies according to the thickness of the block:
- A 7.5 cm thick block has a thermal resistance of 0.90 m²K/W.
- A 36 cm thick block offers a thermal resistance of 5.37 m²K/W.
These performances guarantee optimal insulation against cold in winter and heat in summer, thus contributing to long-term energy savings. IsoHemp hemp blocks are ideal for constructing low-energy or passive buildings.
5. What is the fire resistance of IsoHemp hemp blocks?
IsoHemp hemp blocks are highly fire-resistant. Depending on the thickness of the block and the applied finish, they offer resistance ranging from 45 minutes to 240 minutes. For example, a 36 cm block with a render on the fire side can resist up to 240 minutes. This fire performance ranks IsoHemp blocks among the safest materials for construction, meeting strict fire safety standards.
6. How are IsoHemp hemp blocks bonded, and what is the adhesive consumption?
IsoHemp hemp blocks are bonded using a natural lime-based adhesive mortar. The bonding is done with thin joints of 3 mm, ensuring quick and solid installation. The adhesive consumption varies depending on the thickness of the block, but generally, 2 bags of adhesive mortar are needed per pallet of blocks. For thicker blocks (30 cm and 36 cm), the consumption can reach 6.8 kg/m².
7. Can IsoHemp hemp blocks be used for new construction?
Yes, IsoHemp hemp blocks are perfectly suited for new constructions. They integrate ideally into load-bearing structures made of wood, metal, or with the Hempro system developed by IsoHemp. Thanks to their insulating properties and implementation flexibility, they allow for the construction of ecological houses while guaranteeing a high level of thermal and acoustic comfort.
8. Are hemp blocks suitable for interior and exterior renovation?
Yes, hemp blocks are perfect for interior and exterior renovation projects.
- Interior: They provide natural insulation while allowing walls to breathe—a crucial advantage for old buildings.
- Exterior: They offer excellent thermal insulation while serving as a support for a variety of finishes (cladding, renders, plasters, bricks, etc.).
They are ideal for renovations aiming to improve the energy efficiency of old buildings.
9. What finishes are possible on IsoHemp hemp blocks?
The possible finishes on IsoHemp hemp blocks are varied and adapt to all types of projects:
- Interior: You can apply a natural plaster, tiling, wooden cladding, or specific lime- or gypsum-based renders.
- Exterior: Options include wooden cladding, bricks, brick slips, mineral renders.
These customizable finishes allow combining aesthetics with technical performance.
10. Are IsoHemp blocks compliant with the RE2020 environmental standards?
Yes, IsoHemp hemp blocks comply with the RE2020 standards in France. Their natural composition and thermal performances make them an ideal choice for constructions aiming to comply with this new regulation, which imposes high standards in terms of energy efficiency and carbon footprint reduction.
11. How many hemp blocks are in an IsoHemp pallet?
The number of hemp blocks per pallet depends on the thickness of the blocks:
- 7.5 cm: 84 blocks.
- 9 cm: 72 blocks.
- 12 cm: 54 blocks.
- 15 cm: 42 blocks.
- 20 cm: 30 blocks.
- 30 cm: 24 blocks.
This flexibility allows adapting the packaging of the blocks according to the nature of the project.
12. What are the advantages of IsoHemp's Hempro system?
The Hempro system is a construction method that uses interlocking hemp blocks to create monolithic walls. It offers numerous advantages:
- High thermal and acoustic insulation.
- Quick implementation thanks to easy assembly.
- Durability and environmental friendliness, with natural and healthy materials.
This system is particularly suited for low-energy, very low-energy, and passive constructions, meeting the requirements of new thermal regulations.
