wall studs moisture.

12 posts in this topic

I have a spray foamed fish house with 2x2 walls, aluminum siding and paneling on the inside. Forced air furnace. My walls are wet where each of the wall studs are at. Why is it doing this??? Never seen this happen before with wood studs. Metal studs yes but not wood. How can i cure this?????

I copied this from a transcript:

Metal substitutes of the wood structure are very often being installed without consideration of the difference in thermal conductivity between wood and metal. Strong thermal bridges caused by highly conductive metal components worsen thermal performance of these walls. In metal stud walls, the reduction of the in-cavity R-value can reach 50%. Because steel has higher thermal conductivity than wood and intense heat transfer occurs through the metal wall components, thermal performances of a metal stud wall are significantly lower than for similar wood stud walls. A reduction of the in-cavity R-value caused by the wood studs is about 10% in wood stud walls. That is why metal stud walls are believed to be considerably less thermally effective than similar made of wood.

The issue is that the paneling is wet where the wood studs are

Sorry, I totally misread. Although in this kind of weather the R value of 2 inch wood vs 2 inch foam would be considerable and (heat) cold transfer would be noticable. the only way around it would be to insulate at the stud points, not practical in many cases.

That is what i was thinking. The stud remains cold and thus when the heat hits it you get condensation? I just did not think a wood stud would do that??

did you vapor barrier the wall? I would have vapor barrier the interior side of the wall. Even if i used spray foam. Then put the paneling on.

Just my two cents.

I have a similar problem. I am building a 6x8 perm and when I turn on the heat I have little moisture spots around every screw head in the walls and ceiling and I did poly the inside. I think its the screw itself drawing in cold air from outside and condensating on the inside. I hope its not enough moisture to damage my interior paneling. But, what do you do?

no vapor barrier

wouldnt matter, the moisture is on the inside of the house anyway, and the cold stud is holding it there on the inside of the shack/paneling (condesation). it is probably getting to your insulation however, but if closed cell it shouldnt matter, either way the paneling may be in tough shape in a couple years. could try venting more?

I am thinking of popping the pannelling off in da spring and putting some 3/8th inch styrafoam behind the panneling. would that take care of it???

Do you have an outside vapor barrier? My house does but no inside one and I will have cold spots sometimes when the weather is really brutal, but as soon as it warms a little I no longer have this problem, but you said every stud shows.

Hmmmm??? What was your exterior again, mine is polebarn siding? I am still thinking interior vapor barrier would do the trick minus a few screws drawing in frost. Good Luck

How serious do you want to get? Poly would be better than 3/8 foam. You could try adding furring horizontally to the studs. Hang poly and attach the panneling to the furring. minneman may have the answer: venting. What type of heater do you use? When propane burns, it releases huge amounts of moisture. It is a major problem with construction in the winter.

    •   My Father-in-law (a master plumber) always used to say you only need to know 3 things to be a plumber:          sh*t doesn't run uphill         payday is on Friday         the boss is an ahole      
    • I've been getting them at Costco,  I've checked slyvee and sams but never see them.  Although one of the butcher's at slyvee says he can get them which might not be a bad idea since you can have some fat cut off before you pay per #. I picked one up a couple of weeks ago and it was about 2.80 a #, which isn't too bad yet considering bacon in the store can run quite a bit more than that.  You making bacon or doing pork belly burnt ends moon lake?
    • Excellent summer fishing.  Charters catching strong numbers.  Jig/minnow or jig/leech and bouncers with spinners with crawlers or minnows still producing walleyes. When the wind is right for pulling spinners, they have been lights out.  Walleyes being caught in varying depths, 7-31' of water.  Some shallow shorelines still producing. Pike mixed in all over the lake.    Walleyes in the Rainy River with a better morning/evening bite.  Trolling cranks or pulling spinners a good idea to cover more water. Smallmouth bass are out and about along shorelines and feeder streams. Sturgeon fishing opens again Saturday, July 1st.     Up at the NW Angle, water temps are in the low to mid 60’s. Wind blown shorelines are giving up walleyes via leeches or crankbaits along the weed line. Crawlers on a  gold and/or orange spinner are producing fish out of the mud between 22 - 26 feet. On the Canadian side, bottom bouncers and spinners have been filling the livewells outside of monument bay between 24-28 feet.  Jigging near Skeet and Kennedy Islands have produced nice sized walleye and numerous perch. Great smallmouth action in Tranquil channel and the mouth of Johnston passage. Muskie fishing picking up with high 40” class fish being caught with a few 50's from shallow bottom bays or adjacent to them.
    • Busy time of year out there so if u get canceled it is hard to rebook especially with the smaller operations. Bummer though as it can be a lot of fun if they are biting. 
    • I understand that you never really know when the Warriors are going to fall off or if they even will.  Hopefully the Wolves can make the playoffs and gain some experience, maybe teach the rest of the team how to play defense, so that in a few years we are knocking on the door and can lure in a top free agent to put us over the edge.  Its just an awful tough time to be a good team right now with the Warriors so clearly heads and shoulders above everyone else.
    • I couldn't have said it better myself pikestabber!  We have to go out there and do what we can now and not try to set up for "when the warriors are old" cuz the way the NBA is going who knows what players may join forces to set up the next "Warriors" squad.  Heck maybe the Wolves will be that next team !!  I just really love the addition of Butler and from the sounds of it we are not done yet and I am excited to see what will happen in free agency and if we could really land the likes of Kyle Lowry one of the other PG's that are hitting the FA market.  Nice to see the Wolves making moves!!
    • I would ask Getanet where to get some good ones!   Pork Belly Stinks Started by Getanet, May 1
    • So that means you ALMOST caught a fish!!   Real bummer!
