Advantages

5 great advantages of hempcrete blocks for your project

Hemp blocks maintain a stable indoor temperature and save energy, thanks to their ability to absorb and diffuse heat.

  • Value of λ (lambda): 0.071 W/mK
  • Thermal resistance (R): up to 5.37 m²K/W for a 36 cm block
  • Thermal phase shift: up to 23.6 hours for a 36 cm block  

Due to their vapor permeability, they create a healthy indoor environment with consistent humidity.

  • Vapor resistance factor (μ): 2.8
  •  Equivalent diffusion thickness (Sd): up to 1 m for a 36 cm block

They offer excellent sound insulation, reducing external noise.

  • Sound absorption coefficient (α): 0.85
  • Sound attenuation (Rw): up to 44 dB for a 36 cm block 

They are fire-resistant, without toxic gases, and provide safety in case of fire.

  • Fire resistance: up to 240 minutes for blocks ≥ 30 cm, and at least 45 minutes for 7.5 cm blocks.
  • Reaction to fire class: B-s1, d0  

The blocks use a renewable material (hemp), demonstrating a low carbon footprint and a long lifespan.
