CaNaDry is an insulation material consisting of hemp shives, lime and a natural binder. Roofs, floors and walls can be insulated with this 100% natural and fully recyclable material. CO2 is stored both during the growing of hemp and as an application.

After installation, CaNaDry still stores CO2 from the atmosphere through the permanent carbonation.

Made from

  • Chalk
  • Hemp

Production Process

  • Sowing the hemp.
  • After four to five months, the hemp is harvested using a harvester.
  • Debarking the hemp plant, using a debarking machine. This means that the fibers and the hemp are separated.
  • Production of CaNaDry: hemp shives, lime and a natural binder are processed into a mixture using a mixing installation and drying tunnel.
  • Bagging of final product in different sizes.
  • To install:
    • Product is dumped or blown in
    • After decomposition, the product can be 100% recycled and/or used as a soil improver.


CaNaDry is used for insulation of walls, roofs and floors.

Environmental impact

  • The hemp plants purify the soil.
  • They also remove a high level of CO2 from the air. For example, one hectare of hemp can store 22 tons of CO2. Hemp can be harvested twice a year so this doubles again. This gives you 44 tons of CO2 absorption per year per hectare. To give an idea of ​​how much this is now approximately: a car emits about 120 g/km of CO2. This ensures that CO2 is absorbed that is equal to 488,888 kilometers driven. This is about enough CO2 absorption to drive twelve times around the earth from 1 hectare of hemp.
  • This is a 100% natural product and therefore recyclable, reusable and free of harmful substances.

Good to know

  • CaNaDry is moisture regulating.
  • The excellent sound insulation, which contributes to better acoustics.
  • Excellent phase shift > 16 hours.

Growth opportunities

We don’t just cause change, we need the entire chain for that. In addition to producers, it is also important that customers, architects, contractors and the government are convinced of the importance of going back to natural/ecological insulation.
