Yeah... Its humid here, but not drastically more than we have dealt with in other regions of Canada... but most of the houses in our area are 100+ years old and many of those aren't upgraded to be nearer to modern standards or have only been upgraded in the last couple of decades... they survived our climate without issue so its really not too bad. If we lived in a huge climate difference like Brazil... I would expect
issues. Its just marginal changes and I was told it would "do well" in this region by the company. I appreciate that ill building gaffs like your neighbors might contribute to mold, but the basic structure is the issue here. Its not a suitable dwelling for our region. Its well vented and just trying to keep warm is the issue... venting it as much as we have makes that difficult. There is going to be an unintended constant moisture reaction happening at the exterior wall area regardless of our dampness just because the constant clashing of freezing outside the walls and on the walls meeting the warmth from the stove. If you look at the walls having condensation issues and in the midst of all the running water and mold is a properly engineered double pane vinyl window I put in after market, that isn't having any issue at all with the condensation in the yurt or in our general region... its pretty obvious that its the yurt and materials failing to deal with the cold properly. Realistically, if the damp and humidity was so bad in our region that it could produce such effects inside our yurt then it should extend to the whole yurt and the vinyl windows . If its a general regional issue, it also doesn't explain why the windier colder side of the yurt is laced with issues but the tree lined side isn't. I do understand dampness and I've seen it in action in homes. I think it can definitely affect a structure, but the issues suggest that's not really what is happening. Its not "that" damp here to be responsible for ice on walls doors and domes and running water on the roof and walls. I don't really want to get into dehumidifiers at their huge cost and the cost of electricity here is so wildly expensive as it is... we really can't afford to run more appliances to deal with issues that shouldn't be an issue. The reality is that its too late for this yurt now. I really can't handle any more cracked, rashed, bleeding skin with the cold and wood stove as it is... removing more moisture will make living here completely crippling. The air in the yurt after the stove is doing its thing is already pretty dry. I can get a hygrometer to prove this point in the winter, but its a dryer inside environment inside than I've ever had to deal with anywhere and its making my skin issues worse.
It is likely the worst of the issues begin at night when the temps drop and the wood stove doesn't have enough regular attention because we're sleeping. I get up twice a night to stock it to keep it warm enough by morning (its a stove with a 12 hour unattended burn and its that cold in here i have to keep stocking it all night). If the temp drops below 70 degrees in here the walls and doors ice up (the thresholds are constantly iced up). Then we have to get things warmed up around 100 degrees and wait for daylight to arrive and help with passive solar energy and things melt and thats where lots of the issues are. Its unhealthy to live in an environment thats constantly 90 + degrees esp in the loft where my kids sleep and I wouldn't be able to sleep more than 2 hours at a time at night to maintain it.
Basically due to the extent of the damage to this structure from the flooring up is beyond reasonable repair. The amount of gutting and replacing and having to repurchase materials from the manufacturer would become very expensive... like, to the tune of a new cement foundation for a new properly insulated home... and putting more money into repairs with the same issues at play would be unwise.
I bought a yurt for a simpler life. There was hope through suggestion, that it would bring down my cost of construction and living so I could give my kids something better. That wasn't the case. I don't think its fair to embark on a product promised to be suitable and now my full time job is repairs, condensation clean up and spending more money and effort on repair maintenance issues that shouldn't even be a consideration in a living space. I'm not spending much time able to focus on life when I'm so busy trying to curb issues that most structures never face and the rest of the time I'm sick and can't breathe from mold while watching my life savings circle the toilet. I followed all the company specs and maintenance, I've followed all current building codes, I do what is reasonably expected of a home owner to maintain their dwelling and my regions dampness may differ slightly... but looking at evidence, isn't really the reason for the issues. My yurt sucks and is mold infested and rotting after only 4 years because its a yurt and a poor design. If i could save another person from going through this and they want to listen to reason... I'd like to. That is originally why I responded to this thread. I've made my peace with my loss.
Thanks for the suggestion of the "working hands" Bob... i actually use a lot of that! I have it on my night stand and in the living room and kitchen lol. It is decent stuff and not too pricy. It never really cures or heals much of it... but it helps alieviate the pain for a while and thats worth SO much.
