i didn’t spend a huge amount of time researching which was the most eco option before i bought it (partly because it is for the yurt – not the official eco-build project), but check this out:
the “greenest of the green” insulation choice. hooray
and it is particularly good at keeping temperatures down in summer and keeps insulating when wet. perfect!
i’m increasingly concerned about the non-breathable fabric i built the yurt from. it gets very wet on the inside, but since the sheep’s wool deals well with moisture i’m going to put it up and see what happens. i mean if it insulates well, then the air next to the yurt canvas should be much cooler than the air inside the yurt, thus solving the problem no?? we’ll see
