Like sunshine, I've come into a huge amount of raw wool, a couple years old, and stinking like a barn. I'm planning to use it to insulate a small (10sm) structure, by packing it tightly in a 4-6" gap between wattle walls, as I weave my way upward. Then I'll thickly cob or lime plaster over the inside and outside of this layered "wall". I'm hoping this will help to add some insulating properties to what would otherwise just be a mass wall, allowing me to trap some significant heat in our cold climate, and reduce the amount I need to burn.
Has anyone used the "stuff" method to insulate with wool? And/or used the wool in its raw state? I would pick out twigs and cut out any exceptionally dirty sections, and I would spray it with a borax & water solution and weave some wormwood in there, as others have suggested. Wondering if its likely that the smell would be detectable trapped in plaster.
Thought I would post first on this very helpful thread, and see if I get any responses, before starting a new thread... Would love to hear updates on the projects that prompted this 6 years ago!
