Slab System, your hemp solution for large-scale projects.

Why choose the hemp block with the Poste-Platte System ?

The Poste-Platte system, combined with hemp blocks, offers an optimal solution for large-scale buildings.

Hemp blocks create a homogeneous and high-performance envelope, ensuring exceptional thermal and acoustic insulation.

Suitable for urban renovations, this system allows for the modernization and insulation of existing structures while reducing the overall carbon footprint.

Additionally, it offers great architectural freedom by combining flexibility and performance in complex projects.

The technical performances
of the hemp block in the Poste-Platte 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.
