From havelock: Havelock Wool comes in at an impressive R Value PER INCH of 3.6 for Batts and 4.3 for Loose Fill. Just for those wondering. That is better than fiberglass.

Wow, simultaneously inventing! I’ve been saving waterproof feed bags and shepherd shed-these dogs drop sooo much winter insulation fluff in late spring. I’m going to stuff and seal the bags, glue magnets on them, and then use them as giant, reusable, insulating roof and siding tiles for my poultry houses.

i’m not vegan, but i don’t know how to feel about these; yall did a great job explaining that it is a question of scalability, and that the US is having less and less sheep… but it would be impossible to isolate every home with wool without some unnecessary exploitation.. if i lived in a place with a lot of herds that i knew were being treated fairly i would be more okay with that than buying shipped wool… to be fair NZ has nice animal rights laws, but if it was local it would be a different story. now to isolate that house it would take a year for a medium size herd to produce that much wool, meaning we would need a medium size herd for each tiny house built each year…

Sheep are good for milk too, so when you add to the meat and wool, they are reallly really valuable to keep. Especially since it's easy to feed them and they also give you free landscaping and fertilizer. You can even hire them out to your neighbors to graze their property (works well with chickens!)!

@Acorn Land Labs Hello guys i love your videos :-) I have a question, i noticed that in USA peeps who insulate the walls and roof but not the floor. Are there any specific reason not to insulate the floors? The cold really can go though the thin wooden layer. I think for the confort would mean a lot to insulate it too.

Do you know where you can buy this insulation in NZ?

What are other options for insulation? I’m trying to use as minimal animal products as possible.

It is flame resistant and self-extinguishing. Havelock does not introduce any synthetic mixes, glues, or bonding agents to the product, but does add a small amount of non-toxic boric acid (less than 1%) to make the wool insect repellent and further reduce flammability

I don't know if your comment is in reference to the wool insulation. However, sheeps wool is naturally flame resistant, it will char but the flames won't spread. And in the event of a house fire, the wool won't release harmful toxins unlike some types of insulation. Plus, growing up on a sheep station in central NSW, we have never seen a sheep catch fire or spontaneously combust, which I find quite reassuring 😉🐑

It would boil down to three factors. A) How long does it take to shear? B) How long to clean the wool manually? C) Are you ok using loose wool to insulate vs the 16" batts we're using? The insulation batts require special machinery to make, this is where Havelock excels. We love the batts since it speeds up the process big time for walls and ceilings. If you are game to shear, clean and use loose wool there's nothing keeping you from using home grown!

Selling wool in Alberta Canada has become not profitable at all. So many sheep ranchers who grow for meat are burying their fleece after they shear because it costs more to pack it etc than it’s worth. WHY are there not more producers of this form of insulation. I can’t stand using raw fleece because of the smell (lanolin makes me aaachk.). This seems like such a missed opportunity. This is what our ‘carbon tax’ in Canada should be paying for, setting up the production of wool insulation to make it affordable.

"Chemophobia" XD You sound like a bot from Dow Chemical.

While I love the exploring alternative options there’s a reason even sheep farmers use artificial insulation…… Gonna need y’all Christopher Columbus’er to calm down maybe y’all kids need to start asking 1 simple question….. If it’s so good why did people stop using it especially the ones that produce the raw ingredient. But let’s start with Moths well Havelock treats with Boric Acid but boric acid breaks down at high temps so no really a good choice to use as insulation especially on a dinky shed. Airborne Borates have a half life of a few days. But marketing sounds good if all you need to hear is “green” I guess. So if Moths don’t eat it when the Boric acid decomposes it gives off water and moisture inside walls is never good. Congrats on the KZread shed that looks good but will strangely be missing from farm by 2025
