Hello there, (great site). I am going to build a cottage 2 hours North of Toronto Ontario. winters are cold and dry, summers are hot and humid. Because the property is water access only, winter usage will be low if any. But in spring/fall when night temps drop maybe to 25 f to 35 F on a cold night we will have the pot bellied stove crankin'. I should mention that the cottage will be built on sono-tubes above grade by 2 to 2 1/2 ft
1) I was thinking of using 6 ml poly with bat insulation for the walls and ceiling, but I have a little concern. When the cottage equailzes after I return to the city on Sunday after the weekend, the interior will be subject to the moisture condensing factor instead of the framing members (that is) if I did not use insulation/vapour barrier at all , or the insulation would be affected if I did not use a vapour barrier.? is this just the lesser of 3 evils, or what??
Oh the floor? I was thinking of stapling paper backed bats to the warm side, on top of the joists before I lay the T & G ply (or aspenite), because trying to lay poly on the floor and then trying to ram plywood together might become frustrating, and this way I will not have to go under with insulation. After I was thinking of stapling chicken wire to underside of the joists to discourage (at least) some of the wildlife
Does this sound like the right way to go about this?
Thanks ahead of time

Heat transported moisture, air transported moisture and Relative Humidity (RH%). All three are temperature influenced. Therefore when the pot belly stove is not in use, condensation is highly unlikely.
So your application is fine.

I'm not sure we are on the same page, the cottage will be using the stove (wood burner) so let's say Nov, chilli Sunday night, outside temp.25 F inside cottage 78F. packen' up goin' home for the week, sometime sunday night the cottage equalizes and moisture condenses inside the cottage damp, moldy
should I crack a window in that situation to allow the heat (moisture) to escape?
Thanks!
