Choosing Floor Insulation

[hierony]

Hehe. You don't need a chainsaw to cut strawbales. They'll usually have 2, (sometimes 3 but on heavier/bigger bales or for hay) loops of either baling wire or baling twine. If you cut the wire/twine (knife or wire cutters), the bale will decompress and you can grab small or big flakes out of it.

The thickness of plywood depends on how springy you want things and how much you want to spend. A 20 ft/6 meter yurt will require 11.5 sheets (4x8 ft). Yves used 1/2" thick and recommended thicker; if your straw bale platform is tight together and level you might be fine. I used 3/4" OSB and it was alright, but there was a few weird spots in the strawbales.
