I worked on a few buildings where they used straw balls lenght wise. They had meter thick walls and it’s very efficient. One of them only had a tiny wood stove
just an air gap is not that good as convection will move the air around decreasing its effectiveness. Most insulation is just a way to try to keep the air in place while the air is doing the actual insulation

When you have a meter… I think anything will work as insulation
I mean at that point a meter of air gap alone would be amazing insulation.

Thats not efficient in terms of space though, you’d lose a lot of floor area that way.
