Hemp Fiber Insulation For Non-Toxic Walls (Hempcrete, Hemp Shiv Options)

[@danielhanawalt4998]

From what I'm seeing about using hemp foe building products it looks like hemp will become much more widely used and cost will come down. Considering how fast the plant grows it looks like a more sustainable product and eco friendly. I was wondering about the weight and how hempcrete compares to concrete. Also the durability by comparison. Good video.

One big reason for the Hemp-Shiv outer layer is better insulation. So, what's the R value per inch for the two options?

[@cassityart7001]

Would you consider making a natural wall building project using these techniques? 🌞🌱❤️

[@thiscobhouse]

I want to construct a building using one of these hemp materials soon, but in the meantime, have you watched me build the straw-clay house? kzbin.info/www/bejne/qaeZnImVm95lbdU It's a very similar process.

[@skobiekilla]

Can hemp crete be used as a insulation layer in between 2 earth rammed walls to get that R 40.? What r value is the maximum?

[@Majoofi]

Love to see more experiments like this. What about the compressive strength? Does that matter?

[@thiscobhouse]

These would both be used as non load-bearing infill, so I doubt the compressive strength would matter much in this case.

Is the shev flammable? I would think the one that has lime world not be flammable... not sure. Thank you for this video

[@thiscobhouse]

The shiv, much like straw-clay, will be highly flame resistant when covered with the mud slip, and even much more when coated in the lime binder.

[@terrya9683]

@@thiscobhouse thank you.

[@roiad876]

Can you compare hemp vs woodcrete or papercrete? Very interesting information.

[@yitzhach]

What pozzolan would you recommend with the lime when using the shiv?

[@tamaraelliott8612]

I asked on 8/ 26. Also walls will be under a roof,so mostly out of direct sun I enjoy your book!

[@moreliferemz126]

Thanks for the video mate… do you know the mud slip version is good for sound proofing a room?

[@johntherat339]

I did the exact same test (clay as binder + hemp shiv and hemp + lime) and had pretty much the same results. I liked the adobe-crete results better but they will release more water as it takes way longer to dry. Would love to see a video of you plastering these if you are up for it.

[@tamaraelliott8612]

Nameste 🙏 Question...Is it nesssesary to sift my moist clay rich,rock free soil before mixing with other ingredients? This Cobb is for walls in the house. Also how much time between 2' courses to dry before next course. Walls are 18" wide.Also Nepal is 98 present humidity and around 100 degree's! I'll be using forms and your duel wall system with stawclay . Thanks for your info 💙🙏🌍😁

[@tamaraelliott8612]

We will be using tarp mixing method

[@PeterGurba]

this with leafs ,, how they cut crush it?

[@PeterGurba]

grow your own run it in chipper chopper

[@PeterGurba]

any fire bricks

[@Michael-eq8th]

If you were insulating a floor system with joists and plywood tacked under, would you need to bind the hemp at all?

[@thiscobhouse]

No, but I would personally use a hemp batt insulation for a floor insulation. Hempitecture makes these.

[@rhiannonmitchell5862]

Hi I am a student and am really interested in cob and hemp construction. Is there an alternative to a concrete foundation that you recommend? Additionally, being in Arizona, where the climate is very hot, is there a way to insulate cob in the middle of the wall rather than on the exterior? thanks :)

[@thiscobhouse]

You can potentially do a stone foundation instead of concrete. Here's my video on the ways to insulate a cob wall: kzbin.info/www/bejne/foGTaHumpd6gpqc However, cob has high thermal mass and generally does very well by itself in arid climates.

[@elmarama1396]

Would you use any of these two in a modular type house where you have OSB board on the outside and inside, using this in between?

[@thiscobhouse]

Yes, I think either one could possibly work for a modular build.
