Moisture problem

[kevfish1]

Need some help solving a moisture problem in my new wheel house. The paneling gets wet where all of the studs are at. The walls are 2x2 with smooth aluminum on the outside for siding. Spray foam insulation. I took one of the sheets of paneling off and the face of the stud was wet and cold. So what is happening is the 202 is transfering the cold in and then condensing. Would just a vapor barrier solve this??? or maybe sill seal on the face of the 2x2 to add a little r-value?? Please help

I have the same problem. what i have done is cracked the window and turn up the heat. it seemed to help a lot.

I would look at some past posts and maybe try searching. I remember a identical post to this from a few weeks ago

is the heater vented properly? Sounds to me as if you have too much moisture and the water vapor from burning propane could be a major - and dangerous - source.

better check you co levels or we might be out a couple fisherman sounds like a very bad heater problem i would bring a co detector out with you next time mine in my home has a battery backup that would work just fine for the piece of mind

knowing that fishing is not going to kill you

It is a forced air furnace that is vented properly and no CO

When it's this cold you have to ventilate as much as you possibly can. The cold transfers in through the studs and the humidity condenses. The more comfortable you are the more of a problem you're going to have.

Also, put a vapor barrier on the warm side of construction. Did you build this yourself?

There is no need for a vapor barrier. The spray foam IS a vapor barrier. The colder the air, the less moisture it can hold. The less it can hold, the more you will notice condensation. Thermal transfer compounds this in a fishhouse. We always add a small two inch vent hole with a louvered cover inside and out to help get rid of humidity. You will not notice the cold air from the vents and you will have less to worry about with CO.

A 2 X 4 has an R value of something like 1 or 2. The insulation you have is probably a 11 or something like that. The colder 2x4's are going to have condensation form on them until they start to warm up. The super-cold weather last week probably meant that wasn't going to happen. I suppose you could take off the sheathing and put a bit of foam on top of the 2X4's to break the transfer of the cold but that sounds like a lot of work. The vent as noted above is probably a real good way to deal with it.

The wall studs are just 2 x 2. The ceiling is 2 x 4 and does not do it. I am going to take all the paneling off and ad a vapor barrier and put sill seal on all the studs just to add a little r- value. Then put the paneling back up--- hope this fixes the problem
