I have searched through the Forum or documentation already, but could not find anything about Blow in Cellulose Insulation with e.g. Cellulose.
In my case I am at the very beginning of thinking of a Wikihouse project. To ease building the blocks I think of on site blowing in the insulation after building the structure.
There was a question about this in one of the live videos. I can’t recall which one it was though. I think the consensus was it’s not impossible, but there could be issues filling all cavities as the blocks due to the support parts inside the blocks. I’m not sure if the mess/trouble of reaching all cavities would be worth it. You’d probably need to design in access points to your blocks, and consider the implication these would have on airtightness/drafts.
