The Truth: Metal Buildings And Moisture - Part 1

Metal buildings sweating, condensation and moisture problems.

[@Jonh707]

“Flash spray” a 1/2inch to 1/4inch with “Closed cell” spray foam insulation, then re-install your bat insulation. A flash spray is a way cheaper option and Will completely stop the metal from sweating and will give your entire building an airtight seal. I’ve sprayed thousands of metal buildings and this is definitely the cheapest and best option !

I built my bardo last year and have ZERO water. We put the insulation barrier between the sheet metal and metal beams. In other words my sheet metal is screwed through rolls of insulation that has plastic on each side of the insulation; then screw to the steel beams. I have no sheet metal touching the framing, so no sweat transfer. Then, the living area is framed about 4” away from the siding because of the steel beams. This allowed us to have a natural air gap. We installed regular insulation between the 2x4 framing, so we have double insulation. One on the outside of the building and one on the inside. I wish I could attach a picture. It’s brilliant the way the contractor buttoned up my bardo.

[@sherrie9241]

omg, I never even thought of that....but yes, the water from the cement would have to go someplace..

[@Lotusutra1]

Cement also acks like a sponge. It soaks up water and then releases it into the air. Water pressure in concrete is called hydrostatic pressure. They have little instruments that can measure the amount of water in the concrete to see the amount of moisture saturation. Moisture can pop coatings off the floor. I glued plastic wrap (so there's no holes) on a cement basement.

[@impalaon22inchrome]

I just found your channel and love how real yall are. As a carpenter and owner of a small constructions company, also a building science nerd 🤓,an air gap is the absolute fool proof way to allow the building to dry out. Another suggestion would be to get more insulation on the exterior walls between living area and the siding(i.e., add additional strips to your studs,for thicker insulation, to slow the air changes even more. Look into rockwool insulation. Unlike fiberglass,which will absorb water and lose its "r" value, rockwool repels water and has more "r" value per inch. Depending on your climate, more insulation may be necessary than here in sunny fl. to stop condensation. If yall have any more questions or concerns, I'd be happy to help you all I can. A mentor/building scientist joseph lstiburek has a ton of information on this subject. Good luck, love the channel...ALSO, if the slab doesnt have a moisture barrier under it, you will want to apply a liquid barrier before you install flooring.

[@LaidBackLiving]

Sounds good we really appreciate the input. Thanks for watching.

[@demammoet]

@@LaidBackLiving there's some debate about rockwool vs air quality, you may want to look at wool insulation. Premium price, but you can mix and match some insulation materials. The paper based insulation is s also great (cellulose) but you need to familiarize with each insulation type. Wool is extremely specifically well adapted to the condensation issue. Rockwool comes in second but I would consider it more for vented attics and garages. That said, fiberglass insulation is bottom tier insulation and with a very low real scenario insulation value. Wool cellulose and mineral wool score highest, wool requires more support when applied as it slumps. Cellulose can slump and mash together under damp pressure but also seals a little under the right conditions, which can be a positive or negative depending on where it's at. There's the super expensive denim insulation, but it's packed tight, loses it's fluff, very moisture sensitive, so still excellent for interior privacy walls if you're framing in posts and drywall partitions. All together, my favorites are wool denim and cellulose, wool and cellulose are good for exterior walls, denim isn't, rockwool has some nasty stuff in it, and never forget. All tech is graveyard tech.

[@NotOnYourLife]

You have no air gap between the metal siding and the heated building. You will be fighting moisture issues forever. The metal will condensate and with no airflow it will not dry properly. To prevent this, install 1x4's on the framed walls and then install the siding onto the 1x4's. the way you have it, the metal is directly on the Tyvek, no air gap between them with no place for moisture to go.

[@billedgecombe9040]

Jack is correct . not trying to cause any grief but (I am 40 years commercial construction as carpenter)in this video it looks like the walls are furred out with 2x4 on studs then tyvec ,then metal , as you say if tyvec had been installed on framing ,not on 2x4 furring, you would have your air space and a channel for moisture to travel, i think the proper way now to eliminate the problem will be to take out the insulation ,remove tyvec and reinstall with tyvec on interior side of 2x4 furring ,taping all seams and acoustic sealant to floor .Moisture is your enemy ,mold will make you very ill and destroy your home ,like i say just trying to help not crapping on anyone's parade , i love your channel and we all have lots to learn forever. not a massive job if you do it in smaller sections. this is just my opinion .

[@JS-xs5hq]

Brother, think about installing a heat shield between the woodstove and the wall behind it. Exposing the stud work to direct even just low heat temperatures will eventually lower the kindling temperature of the wood. It helps reduce the risk of structural fire down the road. Thanks for the advice about trapped moisture in steel buildings.

[@FrugalBuilding]

Another way for moisture to get into the walls and condense is through any electrical outlets or light switch boxes. If you have any installed on the outside walls you can use Great Stuff foam around and behind the boxes to seal and prevent moisture from forming inside the walls..

[@danchesney631]

The vapour barrier must always go on the inside warm side. This is true for wooden buildings as well. Poly plastic is a vapour barrier, it goes on the inside, & must be sealed with tape or acoustic sealant, to prevent moist air from penetrating the wall & reaching cold exterior. Tyvek is not a vapour barrier, it goes on the exterior cold side, where it can release any moisture that forms on the cold side of a wall. The problem with steel skinned buildings is that the steel skin acts like a vapour barrier, and so, the installation and sealing of a poly vapour barrier on the inside is critical. The ideal time to insulate and vapour barrier a steel building is in cool/cold weather, before the interior is heated. If you heat the building in cold weather, before you insulate & poly vapour barrier, you’ll be in the cycle you described.

My pole barn had the same problem with condensation and it raining inside. My entire pole barn is wrapped with a house wrap so I didn't understand where the moisture was coming from. I asked a contractor friend about it, he told me that I wrapped the building when the gravel floor was wet and the moisture was coming out of the ground. After the ground dries out the rain inside the shop should stop. Sure enough the moisture and rain inside my pole barn on the warmer days has stopped. I don't remember when you poured the concrete foundation but concrete has a lot of water in it that has to evaporate out so you might have been getting the last little bit of moisture out of your concrete floor. :)

[@davidarnold344]

Adding an active radon fan to your slab will also save your life but help dry your slap and keep ground moisture from getting in

[@1806StoneHouse]

Good discussion. It’s good to understand the building science and there are many ways to “fix” any issue. I would have probably used spray foam ( closed cell ) and that would have worked good. But, it’s also the most expensive option. When I foamed The stone house, I instantly saw a HUGE savings in heating costs.. and my 8k in spray foam is probably going to pay for itself after 5 years.

[@Fbarts]

We built a 60' x 60' metal building, half is living quarters and half is garage and shop. We decided to put the spray foam in and delay some other aspects of the building until later due to money concerns. No doubt the ONLY way to go.

[@futureadventure7299]

Running dehumidifiers for 2 years is the best thing in a new house. Fabulous presentation for the practical approach. I have seen sweating and moisture problems even when spray foam was applied. You did better than professional builders

[@PootsPastures]

It's interesting the "Marshal Remodel" just posted a video with a huge moisture issue in their walls. Same type of metal building, I figured it was an issue with the metal siding and tyvek issue as well as what seams to be issues with their spray foam insulation. Glad you got it all figured out!

[@AugustusLarch]

I am on a crew at times that builds Metallic brand commercial buildings. There is no vapor barrier on the outside. Not on the roof or sidewalls. But vapor barrier the inside. Not a membrane but a barrier. 10 mil poly perforated with liner panel screws with no rubber washers. This way any vapor escapes from hot to cold though the interion screws through an R-48 equivalent fiberglass metal cavity insulation to the outside. During building I have witnessed pooled rain, snowpack and ice develop on the floor. After enclosure and heating, I have seen all of that dry out and escape overnight. It really works well. All that vapor escaped though small, hidden closure gaps and j trim gaps on the roof and walls. All specifically engineered to allow rapid evacuation of moisture. I would build anything like this now unless it has cornice and ridge roof venting. It is a good lesson in vapor control. Very economical without resorting to the expense and problems of spray foam. Never try too hard. Just understand the mechanics of vapor control and apply it to construction details. Always provide a plan for airflow to the outside. To make a structure vapor-tight but not airtight. Because airtight structures will rot and rust everything vulnerable on the inside unless active measures are emplaced. Why deal with that expense. When passive control is possible.

[@lovethatbluegrassmusic9899]

For years I have heard storys about the moisture issues related to quonset huts. My friend owns an old fashioned one that he uses as an out-building. He complains about the thing being oppressively hot in the summertime (in Michigan) and also he complains about his tools rusting inside it. Lets go a step further and incorporate the idea of living in a quonset hut. In a way you would be living in a metal tank. It is sealed up. Moisture is generated from many sources. It is expelled from you and your family and pets breathing and perspiring. There is showering moisture is in the air. There is moisture is generated from drying dishes in the dish rack. One byproduct of a flame is water so when you use your gas cooktop or oven, moisture is generated. Plus the moisture from boiling water is generated, or other cooking such as a casserole or beef roast cooking. you come in from the rain or snow your clothes need to dry. So that adds to the moisture in the inside air. And to top it off there is the condensation issue related to the metal. If the weather outside the metal goes below the dew point, water condenses on both the inside and outside surfaces of the metal. Concrete can sweat moisture too because its porous. So living in one would be a tough nut to crack. I saw many quonset huts in Iraq but they had air conditioners pulling moisture out of them as the hot air was cooled. But they never shut off. Those ones had blown insulation on the inside surfaces of the metal. The foam needs to be a specific type to meet code requirements in the USA. And it should be intumescent too. Plug this into google earth to view a semi quonset hut style roof where no people live: 43°42'16.98"N, 85°28'21.43"W If the wall shown were modified with a side wall made of wood and wrapped with Tyvek, I think the moisture would have a possibility of leaving the building. But there needs to be adequate square footage of flat surface to keep up with what your household generates. Think about this: On a rainy or humid day the inside of our stick-built house feels humid.

[@MitzvosGolem1]

it is a common issue on warehouses we build. Putting plastic under concrete slab helps stop wicking from wet soil into building also

[@footplate0]

So a cheep to use but don't know the cost to install is a heat recovery system. It draws fresh air which then passes through a heat exchanger and is exhausted into the house. The house air is drawn into the other side of the heat exchanger, gives up its heat to the incoming air and is then exhausted to the outside. I do know that this costs peanuts to run as it is basically just a fan that runs. No fancy electrics or other devices needed, just a simple fan. Because the house air is constantly being exhausted you don't get any build up of moisture. Its been proven over here in the European cold damp air. Have a search online and you will find many examples of this system. Just a thought

[@johnobrien403]

That's the way to go, suck out the moisture you are making

[@stefanw5894]

You mention the cost of the spray foam as being too expensive, but what have you spent on batting, tyvek, plastic, dehumidifying, wood stove, aggravation, time, and the possibility that still exists for mold growth?

I was taught you don't want two vapor barriers which will trap moisture. Its either on the outside or inside.

[@stevevice9863]

You will continue to encounter condensation in these types of buildings if they are not flash insulated with CLOSED CELL SPRAY FOAM on every piece of exposed metal in the wall system. Vapor barriers are not completly impervious because of all the holes you have to put in them to attach them to the structure.

[@renewableenergy-ceramiccoa7464]

I watched your blog here and I deal with this issue of condensation a lot. The coating I apply is a “thermal break” when you apply this on steel it does not allow cold/warm to meet therefore it’s cannot form moisture which therefore cannot corrode. In colder climates it also will prevent ice damns because snow won’t stick to the outer roof..no energy getting through for it to melt. I have applied to many different metal buildings over the last 20 years with zero failure. We are not an insulation like polyurethane-we are just a “thermal break” we are currently testing with an Engineering firm to show how effective we are in many applications…this been one of them, although we already know how it works-industries want data…Hope everything you have done has worked.

[@jamesdiyhomestead8263]

You only need one inch of spray foam insulation to stop the condensation. You can use the fiberglass for the rest of the wall cavity.

[@thomashocker2792]

Exactly, that's what I did, no problems.

[@jamieklok3902]

You still need a air space the condensation still happens and it’s worse trapped in the foam .

[@jamesdiyhomestead8263]

@@jamieklok3902 That is only true if you have a way for the air to escape to the outside. ie, vented airway. Moisture can not get trapped in closed cell foam. You do NOT want an air space that is not vented. That is why they put the insulation directly on the walls. If the roof isn't vented then you still put the insulation directly on the metal and use either an hvac system or dehumidifier to control the moisture.

We finished off a small metal shed, however the wood lumber used in building the shed was pressure treated. We insulated like you did and put up a thin paneling, but there was an odor we couldn't get rid of. After about 9 months we ended up tearing down the paneling and realized the odor was from the treated lumber (this was a pre-built shed). We noticed there was growth of either mold or mildew starting on the paneling. Just an FYI for anyone out there who may want to do what we wanted to do with the shed. I agree the spray foam insulation is the best alternative if you can afford it.

[@davidz1681]

I wouldn't use spray foam, I'd use fiberglass just like he did. It would be wise to put a small and I mean small airgap between the metal and moisture barrier. Something like a shim size.

Yeah I'm glad I watched this I need a metal building for my car collection. I'm in Alabama and the moisture is destroying all my cars everything I repair is related to moisture damage and I'm fed up I'm thinking of moving to Arizona but it's not a really good place to live and it cost too much. Also the next place I'm planned to live is going to be on a mountain side somewhere where that evening do that settles and it makes the hood of your car wet at 4:30 in the afternoon that seems to be not as prevalent at a slightly higher elevation. I call the place I live right now moisture pit every afternoon at 4:30 the hoods of the cars are wet. Other places in the same area as long as you go up a hill side it's dry. So I think location has a lot to do with it. There's a reason some pieces of land are cheap and I think that's one of them. It might be fine for growing plants and stuff and if you have any kind of Machinery the moisture is going to attack and destroy. I think even electric vehicles enough moisture gets on that electric motor and then it seizes up and the thing will have plenty of voltage and refuse to go cuz the motor will be locked up from moisture it just hadn't started to happen yet but it's going to and somebody's going to have a burning EV because the electric motor got exposed to heavy moisture.

In the south, with the heat and humidity, you wrap the outside of the house and never put any house wrap or plastic on the inside. I live in Dothan and just built a house. I have a couple metal barns and garage/shop. And have had hardly any problems with condensation. First make sure your building is ventilated properly, especially the roof. If you're insulating the shop and drywalling it, working from outside to inside you should have your siding, then 1x4 furring, then Wrap, then your insulation, then drywall. If you put plastic or wrap inside like this video you're gonna have failures in the south. Check with a local contractor to be certain about your area. Good Luck

First of all, building science is building science Instead of an air barrier you should have used an air vapour barrier like 3m 3015 .. this would allow the travelling of air to exhaust out and vapour and moisture to be blocked from coming in Next is continuous insulation on the outside of your framing in the form of a rigid insulation or a Rockwool.. then you should have had a drainage plane with air space the same way you do with brick on a wall .. 3/4” Furred out wall would have solved all your issues as well. The exterior finish is not to blame for your problem execution of the proper building science on the given application is.

[@markielinhart]

This is nonsense! I have lived in, indeed I am living in a metal clad building. As a now retired builder I have been involved in the construction of many more. I live in a state (Victoria, Australia) that has weather and temperature extremes - from zero to 40*c plus and on some days high humidity. It’s so simple: from outside to in, metal cladding, a moisture barrier wrap, insulated in the wall frame, drywall or ply lining. That’s it. It’s extremely important that the building is AIR TIGHT. Double glazing and cross ventilation as well. Also, insulate the roof and underfloor. I have a split system for cooling and heating plus I run a wood stove on chilly evenings. Never any moisture on inside glass ever or anywhere else either. My advice: start again… ✌️🇦🇺

[@zarazalazar]

Be leary of this advice and heed the video. As an architect we know modern buildings breathe--they don't block moisture instead tyvek/moisture barriers break down water into their smallest constituents so that moisture DOES actually enter your wall assembly but DOES NOT form into dew drops but simply passes through; because water will destroy even metal over time. But, more important!, if your body sweat and everyday moisture can't escape--you can make a perfect breeding ground for mold, spores, and bacteria--which will become airborne. Don't take my word for it, lookup the sad history of Legionnaires Disease and Pontiac Fever Pneumonia from poor building ventilation. I recommend roof ridge vents, dehumidifiers, and always having a quality air monitor on at all times if you're going to build and live in metal buildings or barndominiums. You'll need an extra smart-home (monitors, data producing technology) to stay on top of your health. Good luck everyone.

[@markielinhart]

@@zarazalazar not entirely correct. I don’t where in the world you practice as an architect. What I described was normal building practice in temperate areas of Australia with variations due to climate extremes in the hotter parts of the continent. Any self respecting architect will tell you that an efficient building in cooler climates is an airtight building properly ventilated and to eliminate condensation. Sealing the interior of a building with polythene as shown in the video is guaranteed to introduce buckets of moisture. As I said before my comments regarding metal cladding were based on actualities not theory…

[@johnevans6053]

The entire problem is that there is a temperature difference on the two sides of the metal. The warm side of the metal will always sweat. Like a glass of ice water on a hot day. Spray foam insulation on the inside is your best option. Bat insulation with a vapor barrier will not work.

The moment you try to stop a building breathing using an impermeable membrane you will always have problems no matter what you do. The only place you can get away with metal is on the roof as long as the Ridge cap allows at least some air to escape and take the moisture with it. Acrylic paint is a moisture barrier most people don't think about. Major cause of mildew, damp rot. Never use a plastic vapour barrier anywhere no matter what the building codes tell you. They are the kiss of death to any timber framing, even if you use weather board. Glass fibre causes condensation ! It's glass, just like that window glass you get condensation on. When it gets cold it sweats. when it gets wet, no insulation value anymore. Glass insulation is only going to work in ceiling cavities where the heat in the roof keeps it dry. Trap it in a wall and it fails.

[@jimihendrix8535]

There are millions of houses with fiberglass insulation in the walls. In fact, most houses have it. The way to properly insulate a wall is to stop the heated and cooled air from inside the house from entering into the cavity of the walls (and the best method is sheet rock and paint) and then allow the wall to breath to the outside by not putting any kind of barrier on the outside of the wall (a breathable vapor barrier is ok). It may also be a good idea to put vertical firring strips between the sheathing of the outside wall and any siding to allow an air gap to help the wall dry out if any moisture occurs on the outside of the wall under the siding.

Everything will be wood except for the trusses. I will probably make them out of metal because I want a vaulted ceiling. The wood floor inside the home will be just above grade but will have a 4' crawl space underneath the floor trusses.

[@davidarnold344]

The only solution to future condensation is exterior insulation Outward of your metal exterior.... or an air gap (called a rainsceen ) between your metal and your wrap and insulation. I also recommend you get an ERV . Drafting appliances and hood vents and fans SUCK on a house, moisture will be in the outside air that is replacing the exhausted air, this will come in through gaps and cracks... air infiltration is the other way moisture gets in the walls when it's not moisture drive from humid air going to the drying surface(cold metal , below the dew point temperature) A whole house dehumidifier that is plumbed to a drain and constant air movement will always help. The warmer your inside air is the more moisture it can hold (saturation) letting the inside cool down forces the moisture to drop out of the air. It's dropping out of the air when it his the cold metal. Spray foam will fix this.. If done right. Careful with the spray foam if the chemistry is off the VOCs will be so bad your home will be unliviable, wich the HRV/ERV can help mitigate.

[@mt9372]

I really want to use closed cell foam for my future shop, but I've read comments where people say that when (not if) you get a leak in your metal building, you'll never find the leak, because the foam is obscuring it. I suppose as long as you keep up with the maintenance of your roof in particular (checking for missing/broken screws and rubber gaskets) that it should be a non-issue.

[@DaylnD]

Closed cell foam is a form of a water barrier so you don’t need to wrap if you are using the closed cell and vice versa. One has to be applied to block water from entering, the only problems you may have with closed cell is if you cut sheets of styrofoam and then try to use the closed cell in the cracks, that is looking for trouble. If you use closed cell foam, don’t mix it with another method. It’s very expensive but worth it and has great R- Value

[@JoseFlores-mw7it]

Stucco or pus cement on it with a roller used for painting But fris put the black plastic On one side it has glue and on the other side it has black plastic, then you put the stucco or cement on the outside.

[@akyhne]

Maybe you should have chosen Rockwool instead. Glasswool loves water and is hard to dry. I wouldn't want foam insulation in my house. It's very toxic in a fire, and you can forget all about making it out of the building, before you pass out from the fumes. Luckily it's not legal to use in my country.

[@Franklin-pc3xd]

Mistake #1 - going cheapskate on the insulation - you should have just gone with the blow-on. More expensive but moisture free.

[@LivingTheDreamHomestead.]

Oh man that sucks. Hopefully all that work will pay off and it stays dry. I love that wood stove! That’s a beast!!!❤️ We’re going through draft issues. Gotta love winter time and finding out what worked and what needs work ;) Love your progress guys, keep it up!

Thanks man! And thank you for watching.

[@marymiller9870]

My building was first insulated with sheet type insulation, low value, then inside about 1 ft in where the runs and poles were I had highest r value installed. Then framework was inside runs and sheetrock attached to that. So of course there was an air pocket in between. No moisture since 2013. Thankful for warm/cool home with high end upgrades for about $50K. 22x33. Still thankful✌❤

[@douglassmith2055]

Seems like moisture barrier goes on living space side only, let metal and walls breathe, cold air only condenses at dew point

[@palipali4264]

Metal does not breathe.

[@thouartit]

In a quonset hut or a dome (like I lived in for 8 years), there must be allowance in one or more high spots, to vent the inside air/moisture - out. Ideally one would have a fan vent set up, with a switch down below. The vented air, will drive out moist air really well, especially if you have a wood stove. Using a propane stove in such a space is assee-versee. Now if you live in a giant space, (I lived in 17 foot dome) one must think about insulation and or vapor barrier. I know nothing about this. The dome had a simple velcro patch at the peak. When it got moist inside, I raised the corners, and with the wood stove going, moisture remained perfect. All yurts have the center ring, that contains a small windows that you can open- for example after one showers or cooks.

Did you insulate your slab? Also, does it have a sheet of poly in it? If not, keep that dehumidifier running forever, and also keep a very close eye on the base plates of your 1F walls. :-)

Your having an epiphany. After you see hind sight and 20/18 is perfect 👍 the problems are solved. I worked in a 75 year old steel/iron mill and our equipment was built 30 years before we started running production quotes for the hour. Our company slapped new computer controls on all of the huge boilers without replacing the 48” blast gas valves. This caused our delays and loss of profits on the spot steel markets. We had to learn how to trick the software into letting the huge burners to run pilots to fire these giant monsters up online making 500k pounds of super heated steam per hour and it took forever to warm up them big boilers but once on line our problems began keeping up production and the lives of our Union brothers were dependent on our ability to run 500k pounds of steam per hour 24/7 each and every second of the day all boiler except for (2) of them were on computer controls that never worked properly after first installed by the engineers and they fired them all.

I was glued to moms knee and she had to grab me and run to drag my brother into the house. I just close my eyes and remember it all like it just happened lol 😂

Good info to know. Just living creates a lot of moisture. Looks good for wall finish, now. The tighter the building, the more critical a ventilation system. butyI calking would go along way to sealing the vapour barrier. was thinking horizontal steel, on wood studs, with foam standoff. Closed cell foam spray the existing foam standoff strip top to bottom. Fiberglass pink to follow. I wonder if the expanding foam would bow the steel? Glue the building together with the stuff. Nice vid, very close to what I have in mind.🇨🇦

Spray foma insulation is expensive but in the long run you end up expending more time and money with the other alternatives

[@jeffproulx3388]

If you have 1 pin hole and a mean 1 pin hole anywhere in that plastic water will be in your walls. Cut and see. I promise you will have some in the years to come. You should not have put plastic for sure. Also get rid of that cheap pink stuff. Not trying to piss you off. Just trying to help. i was there and did the same and payed the price. I got rid of the plastic and put super good insulation and now have no problems 5 years later. No plastic lets it dry from the inside and good insulation stops the sweating. That pink stuff is made out of glass and you know what happens when you take a glass of water out side. The glass sweats. Try the same thing with a foam cup. No sweating.

[@ducati748sification]

I just constructed a 40x64 shop. Stick built with metal siding both inside and out. So the layers starting from the outside are: Metal, Tyvek, 2 inch spray foam, batting, Poly, metal. I just pulled a piece to do some plumbing and the spray foam is dripping like a river behind it . Not sure why but hopefully it doesn’t cause mold onto the batting over time

[@thomashocker2792]

Ouch, building needs ventilation. If it molds, that can be treated.

[@wisesaint2]

One inch of spray foam is the only way with fiberglass over that works fine.

[@odin8214]

Some bakeries prefer using propan due to the moisture it contain.

[@court2379]

Burning most fuel produces water, carbon/hydrogen chains -> H20 and CO2. Some CO if it doesn't completely burn. So oil, propane, NG, gasoline, kerosene, etc will all dump huge amounts of water into the space if not vented. I recently added a heater to my shed and it looked like the easiest method would be to use those ventless propane heaters, but after I realized how much water they add, I got a diesel heater that is vented. They only place those ventless are appropriate is with another heater that is vented to make up for the moisture it pulls from the space.

[@caryevans8598]

The insulation needs to vent to remove moisture. I went through this moisture in a few months it will dry out

Double bubble insolation

[@richardheaton3160]

Siding up the wrong way, No poly under the slab, Improper vapor barrier..... omg some people shouldn't build houses. Maybe a tin shed shouldn't be a house, and..... this is why building codes are a great idea. It's just physics.

[@terrylutke]

I wouldn't sheet the interior walls until your moisture/vapor 'fix' is a 100% certain. I have doubts that the interior visqueen sheet will do the job entirely. Also during the cooling season moisture drive works in reverse of the heating season. In that scenario moisture could condensate on the insulation side of the visqueen. There are a couple sure cures, but nothing you'll like hearing at this point.

[@johnnyboy1543]

What in your opinion is a sure cure?

[@terrylutke]

@@johnnyboy1543 Closed cell PU applied directly to the the interior surface of the metal skin, with no gaps. PU thickness application needs to have enough 'R' value to push the dew point away from the interior metal surfaces. Interior wall/clg finishes need to be permeable enough to prevent trapped moisture vapor.

Spray foam would have solved your problem I’ve been doing metal siding / roofs on commercial and residential properties for 5 years we use densglass then Tyvek on the outside and spray foam on the inside

In order for that wood stove to work, it has to draw outside air into the house. Otherwise you'd have a vacuum inside and the smoke would not exhaust--no draft. Same with bathroom fans. Every square foot of air vented to outside will be replaced with outside air coming back in somewhere.
