Mini splits?

[Corinarose]

I would suggest you check out smilingwoodsyurts.com they have wooden

yurt kits

that are pretty reasonable.
I live in a yurt from a company in NH and live in Vermont.
The first two years I used the "winter package" from the company but

heating

it with wood was a full time job for our cold winters.
I have insulated it (walls and roof)with 6" of roxul and it works wonder now and would consider a mini-split now, however there remains the fact that the outer layers are not breathable and create condensation. I have come up with a solution but ultimately wooden construction with current insulating practices is really the answer for anything intended to be permanent.
