HempFlax Panel Insulation

HempFlax Panel Insulation is a natural alternative for synthetic and mineral insulation materials and is suitable for all common building techniques. If you would like to fully exploit the special qualities of this natural product, applying the material in a ‘diffusion-open’ building construction is an interesting alternative.

Diffusion-open building is a much tried and tested building method in Germany, for example. The difference between diffusion-open and diffusion-tight is comparable with wearing an insulating piece of clothing made of a standard plastic foil (vapour tight), or a material that breathes such as Gore-Tex®.

  • HempFlax Panel Insulation is available in a range of thicknesses from 40mm to 180mm

  • Standard panel size of 1200mm x 600mm

  • The heat capacity of hemp fiber guarantees a maximum heat buffering and phase shift

  • The mechanical properties of the fiber guarantee a prolonged efficient lifespan

  • Hemp fiber can absorb 20% of its weight in fluids without losing its insulating capacity

  • Hemp fiber contains no proteins and attracts neither insects nor rodents

  • The production of hemp fiber insulation material requires 10 times less energy than the production of synthetic and mineral alternatives

  • Hemp fiber insulation absorbs CO2 during growth and contributes to a positive CO2 balance

  • HempFlax insulation materials are packed in shrink foil and delivered on pallets

  • The insulation mats must be stored vertically and away from moisture

  • The R value ranges from 1 to 4.5


The term ‘HempFlax-grade fiber’ is used to define the finest possible quality of product. This category covers both finished and semi-finished hemp fiber products, and also technical grade flax fiber.
