Healthy, vapour breathable and carbon negative flexible insulation batts created with UK hemp.

  • Made with UK grown industrial hemp.
  • Soft to touch and healthy for installers.
  • Large net negative embodied carbon savings.
  • Exceptional vapour transport – keeps buildings healthy and dry. Ideal for traditional retrofits.
  • Cool in summer, warm in winter. Indoor temperatures and humidity stay comfortably even due to IndiTherm naturally regulating both.
  • Healthy indoor air quality.
  • Durability tested under extreme conditions.
  • Exceptional rigidity resists slumping.

Storage and handling

Keep dry during delivery and storage. Pallets must not be stacked.


Refer to the installation guide for recommendations. Friction fit between structural framing or against masonry. For best cut use ‘wavy’ insulation blades – available as handsaws or powered dual-blade reciprocating saws.

Environmental impacts

IndiTherm has a net storage of carbon. It reduces waste because offcuts can be shredded and made into more of the same product and it can be reused at end of life. IndiNature also makes a biodegradable product called IndiTherm Bio
