Why choose the hemp block with the Wood System ?
IsoHemp's Wood System allows you to combine the lightness and flexibility of timber structures with the performance of hemp blocks.
This combination creates a homogeneous, durable, and environmentally friendly insulating envelope.
Whether you opt for post-beam structure, timber frame, or CLT, this solution guarantees optimal thermal and acoustic performance while ensuring a healthy and low-carbon construction.
The advantages of hemp blocks in the Wood System.
- Low-carbon construction: Timber and hemp blocks reduce the carbon footprint of your projects, for sustainable constructions.
- Thermal and acoustic insulation: Hemp guarantees thermal and acoustic comfort all year round, while eliminating summer overheating.
- Dry and breathable solution: Hemp blocks ensure a quick and dry construction, allowing walls to breathe naturally.
- Adaptability and architectural freedom: Compatible with all types of timber structures (post-beam, timber frame, CLT), the system adapts to your bespoke projects.
- Ease of implementation: The ability to groove hemp blocks simplifies the passage of technical ducts.
- Fire resistance: Hemp blocks offer up to 4 hours of fire resistance for a block from 30 cm.
A recognised and certified material.
A material recognised and certified by numerous labels and technical approvals.
The Wood System: an ideal solution for every type of timber construction.
Timber post-beam
The timber post-beam system, combined with IsoHemp hemp blocks, forms a homogeneous monolithic insulating envelope.
This lightweight and durable system simplifies interior and exterior finishes, which can be applied directly onto the hemp blocks.
Specific advantages:
- 100% natural and low-carbon design
- Breathable and homogeneous envelope
- Lightweight construction with good thermal inertia
Timber frame
Timber frame structures doubled with IsoHemp hemp blocks significantly improve thermal and acoustic insulation while preventing summer overheating.
Hemp blocks placed inside or outside also facilitate the passage of technical ducts.
Specific advantages:
- Elimination of summer overheating
- Significant acoustic improvement
- Easier passage of technical ducts
CLT timber
CLT (Cross Laminated Timber) panels allow for rapid construction.
Wrapping these panels with IsoHemp hemp blocks improves acoustics and thermal insulation, while offering great architectural freedom.
Specific advantages:
- Quick and efficient construction
- Enhanced thermal and acoustic insulation
- Architectural freedom for complex projects
The technical performances of the hemp block in the Wood System.
Hemp blocks ensure excellent thermal regulation thanks to their ability to absorb and diffuse heat. This helps maintain a constant indoor temperature, limiting variations due to external conditions.
Key technical data :
-
Lambda value (λ): 0.071 W/mK
-
Thermal resistance (R): up to 5.37 m²K/W for 36 cm blocks.
-
Thermal phase shift: up to 23.6 hours for 36 cm blocks, reducing the impact of temperature variations.
Thanks to their permeability to water vapour, hemp blocks naturally regulate humidity, creating a healthy and consistent indoor environment.
Key technical data :
-
Water vapour resistance factor (μ): 2.8.
-
Equivalent diffusion thickness Sd: up to 1 m for a 36 cm block, promoting wall breathability.
Hemp blocks offer remarkable acoustic insulation, effectively absorbing and attenuating noise, for a quieter indoor environment protected from sound pollution.
Key technical data :
-
Acoustic absorption (α): Coefficient of 0.85 (high sound absorption).
-
Acoustic attenuation (Rw): up to 44 dB for a 36 cm block, significantly reducing external noise.
Hemp blocks are highly fire-resistant, emit no toxic fumes, and offer increased safety in case of fire.
Key technical data :
-
Fire resistance: from 240 minutes for blocks of 30 cm or more to 45 minutes for 7.5 cm blocks.
-
Fire reaction class: B, S1, d0. The hemp block does not emit toxic fumes or flaming droplets.
Hemp blocks are the epitome of a sustainable solution, combining remarkable longevity with a reduced environmental footprint. This bio-based material ensures reliable and environmentally friendly construction.
Key technical data :
-
Bio-based and low-carbon material: Hemp is a renewable resource that helps reduce CO₂ emissions during construction.
-
Exceptional lifespan: Thanks to their robustness, hemp blocks maintain their performance for decades without needing replacement.
