The technical performances of the hemp block in the Metal 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.
