Building with Hemp - An Incredible Natural Insulation & Sustainable Material

Рет қаралды 716,641

Күн бұрын

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:

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.

Gene Jordan hemp-crete would be very heavy with thickness needed to have good R value. Maybe they could just use packed hemp without the concrete added, not sure what R value hemp alone would have?

@GeneJordan 5 жыл бұрын

@@longhairmullet You are correct. I had mis-typed that. Packed hemp would work as an insulation. Perhaps Hempcrete would work for the base of the framed out walls between the containers? However, the thermal mass stored in a wall of Hempcrete facing the sun might prove useful in the winter.

@Luckingsworth 3 жыл бұрын

I haven't seen anything here that suggests it cannot be done with other material. Essentially it is just an organic version of concrete madd with fiberglass. The many strands inside do strengthen. The product and possibly insulate. So while hemp could be the best option, it is not unique in this. Fiberglass reinforced concrete is already a thing.

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.

Nice idea, they only don't tell that the insulation ratio is a lot lower than other materials. R2.1 isn't much for that thickness at all. Not to say it's totally bad, but it is something to keep in mind. There are also very good insulation materials made from recycled waste. Less insulation can mean that you need to heat up more, which is in the end is also less sustainable. Ones again, it doesn't mean it's totally useless, but nothing comes for free.

Merlin Gallagher It is R2.1 per inch of thickness and the most common thickness of the hemp layer is 12" so the R value of the hemp wall is R25 as is stated in this video.The best things about hemp are non-toxic to the builders and to the people who live or work in the finished bldg, the material breathes so no problems with humidity, damp, mouldin the finished home; lightweight and easy to work with so non-skilled labour including the eventual owners of the house can be part of the building crew which cuts down on costs and increases sense of ownership and care and understanding of the end product; the beauty of the finished walls and whatever else was mentioned in this video and in many others on using hemp as a building material.

@@shardamatasatyam9148 Thanks for your reply. I am familiar with these materials for many years. Yet I don't always recommend it to people for the reasons I mentioned before. Besides a lot of hemp insulation products also contain "toxic" elements. Also there are a lot of other non-toxic products. In fact most of the products I am familiar with can be used by "non-skilled" workers with no or very little protection.

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..
