Building with Hemp - An Incredible Natural Insulation & Sustainable Material

Поделиться

  • Опубликовано: 25 июн 2024
  • Anthony from du Chanvre has built over 45 houses using hempcrete as a natural and sustainable insulation material. Hempcrete is made with a mix of hemp hurd (fibre), hydraulic lime (binder), and water.
    You can follow Anthony's building projects and get in touch with him on Instagram, or on his website here:
    / du.chanvre
    duchanvre.com/
    Hempcrete is not load-bearing, but it does provide insulation, thermal mass, and it regulates temperature and humidity. The R-value of hempcrete is R-2.1 per inch.
    Some other advantages of hempcrete is that it resists fire, mould, and vermin, and it eliminates the need for a vapour barrier and drywall (gypsum). Instead, you protect the hempcrete with natural lime plasters on the inside and on the outside of the building.
    Using hemp is a sustainable building material because it is carbon negative (it stocks more carbon in the fibre of the plant than is used to grow, harvest, and process it).
    We're very excited to learn about new and innovative ways to use natural building materials in conventional construction projects.
    Anthony says the cast-in-place construction method creates the highest quality of hempcrete, but pre-formed, pre-dried hempcrete blocks are more likely to allow hempcrete to go mainstream.
    In case you missed it, Anthony references a Bob Marley song at the end of the interview, comparing the conventional construction industry to the big tree, and the natural building industry to the small ax that will cut it down:

      although i am not quite sure what sort of sarcasm you are intending, i wan't to state this for those who think you mean that since hemp has been around that long that it is then therefore useless because the world is not a different place.

      It doesn't. You must use concrete foundation as usual. But you can plaster any concrete left showing above ground to match. This product may bring back the plasterers trade but it's super labor intensive and still need carpenters to frame inside walls, roof and floor systems. Only the wealthy will be able to afford this type of building.

      In situation of flood the wall will stand. Lime based mortar don't dissolve in water, they are back to stone once set. After the flood, the wall will dry out because it is breathable, only the esthetic will be affected. That said, hempcrete cannot stay wet or it will deteriorate. Might sound crazy but yes, hempcrete resists fire.

    • @NouriaDiallo
      @NouriaDiallo 3 года назад +1

      Well, hemp hurds have special characteristics, such as open porosity and capillary action, that have a lot to do with hempcrete's performance. It allows the migration of vapor, but also phase transitions : when the humidity evaporates in summer, it cools the wall, if vapor condensates in winter, it warms the wall. It has also a low thermal effusivity and feels warm compared to a masonry wall, allowing to lower the temperature of the air with the same level of comfort.
      Now, it doesn't mean hemp hurds are the only vegetal material with these properties, it just happens to have been used and studied since the 80's.
      It was first used to replace the wattle and daub for the restoration of old half timber houses. It was chosen because it was a cheap by-products of hemp fiber production, and more readily available than straw. But there are now experiments being made with Miscanthus (silvergrass), sun flower stems, and lavender stems (a by-products of the production of essential oils).
      Hempcrete, however, benefits from 40 years of hindsight, and has, in France, been tested by the "scientific and technical center of construction" with regulations and trainings for the professionals. So you can get the 10 years warranty from the contactor that conditions subventions for efficiency improvement, for example. It's even recommended by local authorities, especially in old houses restoration.

      The natural hydraulic lime used in hempcrete production is not subjected to nearly as high of a temperature in the kiln as typical concrete mixes. Although there is some co2 produced in that process, once combined with the hemp hurds, hempcrete is truly carbon negative. The lime as it vitrifies over time will actually re-absorb a portion of the carbon driven off in the firing process.

    Less insulation can mean that you need to heat up more, which is in the end is also less sustainable.

    The labor cost is too high, and the R-value at 2.1 per inch is on the low side for an insulation material. Polyurethane Foam (foamed on site) has an R-value of 6.25 per inch. R-values for fiberglass rolled batt insulation are typically between 2.9 and 3.8 per inch. R-value of cork is 3.00 per inch.
    Hempcrete is also a misnomer since it has nothing to do with concrete. It's not made using concrete and isn't near as strong as concrete. Hemplime would be a more honest term. It's not strong enough to build a load-bearing wall from it without additional framing.

      R Value is one point but is not the entire reason for using Hempcrete. Polyurethane is toxic for you to breathe overtime as it off-gases and your breathing toxic and proven cancer causing materials exposing your family to these elements for some is a non starter. Hempcrete breathes regulating humidity more or less depending on the environment. more in AZ less in FL. Hemp is sustainable synthetic building materials are harming the planet and us. Gypsum has to be mined, plastic for vapor barriers are filling our oceans. Hemp Lime walls are not load bearing and not the point. the way to look at it is Hemp Lime is "Hemp Insulation Installation" These walls also filter the air still, not like when the plant was alive but it does still sequester/Trap carbon from the atmosphere making the interior environment in that home compared to next door cleaner and less toxic. People refer to the sense in a Hemp House as Cozy, Cave like, Comfy, Peaceful. Not for everyone, but those other benefits especially environmental add up for certain segments of the population. A field of Hemp grows in 120 days, makes the same amount of pulp 4 acres of trees produce in one single acre. and filters the air while growing..
