couverture_comblesperdues_c_01_1-2Thermal insulation & acoustic insulation with hemp fibers

Hemp wool® components

85% of hemp fibers
15 % of stable synthetic binder, non-emissive

Density

25 kg/m3 only in rolls 25 or 30 kg/m3 in panels high density of hemp wool® bring a higher thermal phase displacement: The heat takes more time to cross a dense material; in this way, your home stays fresh during the summer.


Use of hemp wool® TECHNILAINE®

  • Roofs
  • Attic
  • walls (partitions)
  • suspended ceilings
  • Internal wall partitions
  • Yurts insulation

Advantages of hemp wool® TECHNILAINE®

  • Acoustic and thermal insulation
  • Moisture management/Breathing wall
  • Resistant to rodents and insects
  • High mechanical strength
  • Great durability
  • Easy implementation
  • Healthy and ecological product

  • Dry thermal conductivity : λ =0.040 W/m.K
  • Wet thermal conductivity : λ =0.048 W/m.K
  • Specific heat in 25kg/m3 : 1370 J.kg.K
  • Thermal phase displacement in 20 cm (25kg/m3) : 4h15min
  • Tensile strength (parallel to the fibre) (NF EN 160812 – CSTB) : can bear twice the product’s weight.
  • Tensile strength (perpendicular to the fibre) (NF EN 1607) : 4171 N/m²
  • Reaction to fire classification : Euroclass F
  • Water absorption (EN 1609) : 3.70 kg/m²
  • Partial Humidification (ACERMI) : No dimensional changes
  • Water vaporresistance (EN 12086) : μ = 1
  • Sound absorption coefficient in 25kg/m3 (EN ISO 354) : αw = 0.65
  • Transmission loss (partition 96/70 with wood R25.060) : Rw = 41 dB
  • Biological resistance (CUAP) : F3 Storage : dry, safety from elements
