Converting to hard walls.

[Corey]

Hell All,

We live in a 30' yurt year round in northern New England. After 8+ years we are ready for more stable temperatures within our yurt and to be able to travel during the winter. (We currently only heat with a wood stove.)

We are thinking of wrapping the exterior wall of the yurt in plywood and covering with t & g boards. For the inside we would use the 2x4s that support the rafters to frame out a curved wall. The wall would have a vapor barrier and

insulation

. For the ceiling I am thinking of leaving the canvas as-is on the outside and on the inside place

insulation

in between the rafters, place a vapor barrier on top of that and then place t & g boards over that.

It all works out neat and pretty in my head but I am uncertain about some things:
1. In a traditional house you would have soffit to let air circulate between the insulation and the roof to prevent mold/mildew. I don't see how to add soffit here. The few pictures I've seen of insulated yurt roofs do not seem to have any special ventilation. Is this something to consider or is there an approach that would mitigate the risk of mold/mildew?
2. The one video I have seen of converting a yurt to hard walls show the owners pulling down the canvas before putting up plywood. This seems like the right approach but I wonder if the canvas can be left in place. New construction uses housewrap and I wonder if the canvas could be used for the same purpose or just left up underneath the plywood. (I know housewrap is supposed to allow water vapor to pass.)
3. Is there something else to consider? Has anyone else here attempted this?

Thanks.
