Hemp Insulation

Product Description

Thermo-Hemp is a natural insulation material manufactured from hemp by Hock in Bavaria, Germany.
Hemp grows up to a height of nearly 4 metres within a period of 100-120 days. Because the plants shade the soil, no chemical protection or toxic additives are required for hemp cultivation. As well as having low embodied energy during manufacture, hemp is carbon negative as it locks in carbon during its growth.

Hemp is one of the oldest cultivated plants on earth, hemp is not only used as an excellent insulating material but also for clothing, paper, oil, fuel, food and other construction materials.

With a thermal conductivity of 0.039W/(m.k), a density of 38kg/M3 and thicknesses ranging from 40mm to 200mm, Thermo-Hemp is the perfect solution for a wall, floor and roof applications in both and new and old buildings.

  • Healthier for you - made from natural hemp plant fibres grown without any chemicals or toxic additives. Thermo-Hemp is totally safe and easy for you to install.
  • Healthier for your home - its hygroscopic properties hemp regulates humidity offsetting condensation risk. What's more, it’s naturally resistant to mould growth and insect attack and has outstanding fire resistance.
  • Healthier for the environment - as well as having low embodied energy during manufacture, hemp is carbon negative as it locks in carbon during its growth.
  • Some insulations are known to compact over time, this results in a significant loss of performance. The benefit of hemp fibres is that they have a natural resilience that enables them to maintain their structure.
  • Benefits of hemp insulation include; Superb thermal performance, excellent sound insulation, low density & high thermal mass, semi-rigid/flexible, never slumps.
  • 1 hectare of hemp will absorb up to 18tonnes of C02 as it grows
