The Hempro System: a monolithic construction solution.

The Hempro System is composed of three types of hemp blocks, available in thicknesses of 30 or 36 cm, each with a specific role in the construction of your building:

Solid blocks: Ensure the insulating envelope of the building, guaranteeing excellent daily thermal and hygrometric comfort. They are the basis of the construction and offer durable natural insulation.
Perforated blocks: Used as lost formwork for reinforced concrete columns, these blocks accommodate the building's structure while maintaining the continuity of the insulation.
U-blocks: Allow the pouring of concrete beams that will support the floors and roof, ensuring the rigidity and stability of the structure.

For even higher thermal performances, a second layer of masonry in hemp blocks can be added, with thicknesses adjusted according to your specific needs.

A recognised and certified material.

A material recognised and certified by numerous labels and technical approvals.

The technical performances
of the hemp block in the Hempro 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.

The implementation of the Hempro System's hemp blocks.

The Hempro system offers a turnkey solution to simplify the realisation of all types of construction projects: single-family homes, terraced houses, small buildings, and much more.
Adapted to building professionals (contractors, masons, general companies), the system stands out for the lightness and manoeuvrability of the blocks, facilitating on-site installation..
