- It's about time to talk about the nightmare of small living spaces like a shipping container house, the water CONDENSATION.
Well, we know you were expecting to watch us installing our ceiling panels today as promised last week, but unfortunately, or fortunately, sometimes we've got to take a step backward in order of taking 5 steps forward in the near future.
So this week we took the time to sit down and do our best to clarify the well-known problem called water condensation.

Come on Monday!!!! I can't wait for the next episode!!!!!
Tomorrow!! But don’t be disappointed that we didn’t finished the insulation yet. We do have a good excuse that we explain on tomorrow’s episode. But We think tomorrow will also be a fun episode!! Hope you like it!!😊😊👌🏼👌🏼
I think you have a bit of a cult following, and don't realize it. Your content is real and very informative. I re-watch episodes and every time I do, I notice something I didn't see when I watched the episode previously.
On Friday evening I watched the Q&A episodes, and I now have a good idea as to the your background and the purpose of what you are doing.
Massive respect.
As a documentary film production team, you are doing well. I hope a television company picks up this series and it gets broadcast around the world.
I have learned so much, and been inspired to build my own tiny home.
Thank you for all you do!
Thanks so much for the support!! Comments like yours is for sure a huge source of inspiration and motivation. 😍😍 For sure getting to know and to interact with people all around the world show us that was a good decision to create the channel instead of just building the house and not sharing with anyone else. 😍😍😍
This is no laughing matter!!!
Closed Cell Spray Foam Insulation will fix the problem.
I don’t think I could ever appreciate enough how the two of you talk on these topics using English as a second language.
Thanks so much for your kind words!! It means a lot to us. 😊😊
@@OddLifeCrafting Seu inglês é melhor que o da maioria dos comentários!
I was going to compliment them on their ability to clearly communicate In English too!
Evans video on the channel Living Big in a Tiny House: th-cam.com/video/sPgjndFqqwY/w-d-xo.html
Your explaining it just fine.. I for one am glad you are talking through your process on camera as apposed to just saying 'here is what we did, it's the best way'
We are really glad you enjoyed Bill. 😊👌🏼
You're (you are) explaining it just fine.
😊😊
Until you find spray foam you may want to consider 2 vents in the lower/ bottom of walls with a cheap humidifier to circulate the air from building up moisture. A steady flow of air will not accumulate moisture. I used the vents from a dryer outlet from your home. This is the best and cheapest way for your problem. I have never had any worries. I have very cold winters and very humid summers.
The two of you are a joy to listen to and I really like how you really addressed potential problems by networking with others to design a unique solution. Bravo! Look forward to seeing progress on your home.
😊😊 thanks so much!!
But they still don't know what they are doing.
Anyway, I have left a comment to share how I am dealing with the mold concerns. IQ 190++ does have some advantage... ... Hehehehehehe~
Your lady is good at explaining in a simple way. Smart + skilled +pretty = keeper.
Hehehehe 😍😍
We just saw this video and we're considering a shipping container house build, so we're very interested in what you did and how it has performed over the last few years.
Rob C at The Off Grid Tiny House had a very small condensation issue in his trailer tiny house, where moisture condensed on the ceiling near one end of the trailer, far away from the wood stove, and followed the contour of the closed cell foam to the lowest hanging point where it dripped to the floor. (Quality closed cell foam is said to be impermeable to moisture, so by sticking to the metal container walls it effectively keeps any moisture from ever reaching the cold metal - which is ideal. However, in very cold climates, the most interior surface of the foam, facing the occupants, can get just cold enough to act as a moisture condensing surface for the high interior humidity that is typical in a lived in space. Interior ceiling fans can act to evaporate that surface condensation and proper ventilation can remove it from the dwelling.)
I visited an earth bermed house that had a condensation problem on the bermed north wall side, where the ground temperature made the wall just cool enough to condense indoor moisture all the time. Since it was a super airtight build, special measures were needed to solve the problem.
Solving a potential condensation issue before you proceed with a build is really your only chance to get it right. If you fail, then you're looking at a possible complete interior teardown to get at a massive mold issue sometime in the near future. Ouch!
Thanks for the video, I think the condensation problem is something a lot of people forget about till its too late. A very good issue I think a lot of people will appreciate that you brought it up. keep it up enjoy your work.
Hopefully we can help somehow others and hopefully we don’t end up with condensation problems 😊
For Bugs issues through the vents of the Shipping container, Purchase bugs screen mesh, Cut to required size and apply it over vent . Use Silicone caulk to hold it in place. multiple layer of mesh is prefered.
👌🏼👌🏼
HI, good episode, been dealing with conventional ventilation problems myself with building our summer shack in the woods. Gluing some net over the ventilation holes is perfect. You might add some small holes at the bottom of the container walls. When the container heats up in the warmer weather it will allow the heat to draw in fresh air from the bottom and move the stale air behind the insulation up and force the air out of the walls at the top. Heat always wants to rise, on warm days the metal can get hot, having a few small holes will offer a passive way of ventilating the space between the insulation and the metal wall. On cold days it won't make a great deal of difference. Mold loves moist hot days.
The reason I suggest this is that on a conventional house you would have airs channels in the roof so that mold doesn't grow, so its the same principle
Personally, I would forget the rubber lining the metal, it's nonporous so coating it with something seems like overkill. If it's well ventilated you won't need to worry about rust.
Thanks a lot for the advices!! We are thinking about the bottom holes it might me a good think. We are only afraid with bigs. We are still worried about nests inside the wall. 😨
Hi guys, the problem with the condensation is that the metal is a temperature amplifier, so I think you should try to apply insulation to the outside of the shipping container.
For sure it’s a solution. 👌🏼
This is something I never would've thought of. Seems important too
👌🏼😊
Thank you for this episode. I watched the boat guy and didn't by understand why he built the box inside his shipping container but now I get it. You just "condensed" weeks of research for me into a short video. Please keep posting
Evrything you said makes perfect sense. I will track down the next episode of course and see how this progressed.
We actually found a material that acts in a different way, so we didn’t need to ventilate the walls 😉
Love your video. I am just starting this journey with a shipping container home in South east Queensland Australia. At a guess we may have similar weather to where you are. I have been thinking about having the back and roof cut into a soil bank to use soil as an insulation. I am learning and education myself on what is possible on a low budget. I love your honest, authentic, no frills approach. I will be watching with interest. Cheers. John.
I live in West Virginia, built a home starting with two sea containers, which is a nightmare. One is aluminum, the other steel. They are spaced 15 feet apart, with a wood structure between and a wood structure on top, as a second level. I covered the aluminum side with fiber barn panel, on the outside, hoping condensation isn’t trapped between. The steel one on the other side is exposed, where I have my kitchen and a wood burning stove. I had a wood cabinet sink, which I replaced with a stainless steel commercial sink and counter. As I pulled the wood sink, it was covered with mold. Now it’s breathing better and not trapped, but the outside of the container is still exposed. I guess I will cover the outside, or build out, with a wood addition, to make my container an inside wall instead of exterior wall. Although, it’s stressful and a lesson learned. The other mistake, I set them down on stone, crush and run, which a groundhog has borrowed under. Now, I have to cut all my floors out and pour concrete. I’m now working backwards. After doing the math, wood building structure is cheaper and better. I advise anyone, don’t do it.
Going through this right now,,so I come up with this idea,
treating the steel as say siding,then use building paper,2x4 with insulation, then vapor barrier,,,then interior sheathing. Of course we will loose a bit more interior room,but it beats having mold in time.the air gap makes sense for sure,
I could not find anything on this topic,,or other vids I did find,left me scratching my head,,,
It's good u guys thought this through,and asked the right people...
Greetings from Canada 👍
Has anyone suggested adding vents to the bottom of the wall to aid in moving the air? Thermal movement of the air will be hampered (IMHO) if you rely on only the upper vents. We do that with our attics with ventilation at the eave and then at the peak or ridge. If you have venting at the bottom as well as the top you will create laminar air flow in the air cavity. Also, sub'd! I l have enjoyed your videos thus far (just found your channel). Cheers from another Canadian.
Thanks a lot for the tip. Right now we decided to go with a different solution as out weather in Brazil is really mild, you will see on the next episode. 😊👌🏼
Great video glad to see one our Canadians were able to help you!
😊Thanks, Ronald.
Hola chicos. La solución a la que habéis llegado me parece genial. Entiendo que lo que os propuso vuestro amigo de Canadá era lo que en España llamamos Espuma Proyectada. Al ver este episodio (de hace más de 2 años) recordé cuando soldasteis unas pretinas al contenedor para dar más firmeza a la estructura metálica que soportaría el aislamiento. En ese momento pensé, muy buena idea pero también recordé el comentario que leí en otro canal sobre que era mejor dejar la estructura interior libre, ya que el contenedor, al ser metálico sufre muchos momentos de dilataciones y contracciones debido al cambio de temperatura y que incluso se pueden oír esos crujidos. Eso quiere decir que si el interior no está suelto, se puede agrietar, sobre todo si se utilizan placas de yeso “peladura”.
Resumiendo, si el aislamiento se coloca por el exterior del contenedor se evitarían tanto las dilataciones y contracciones como las condensaciones.
Perdonad por enrollarme tanto. Un saludo
Sí. Es una buena opción. Pero queríamos que el contenedor pareciera un contenedor por fuera. La idea es protegerlo del exterior con sombras para que no se caliente y se extienda tanto.
Hi Guy's: An addition you might consider is whisper fans in an external metal elbow duct. One fan blowing in mounted on the air vent; a second one blowing out on a opposite corner . Even though they are less than 100 Cu. ft. per minute; this might remove any moist air. And can be added later if needed. And I would run the idea past your current advisor first. the old guy Bert
Thanks a lot for the suggestion Bert!!
Yes, I also have this. a 12volt DC computer fan on each vent, one pointed inwards and the other pointed outwards, would do the job nicely, and they would run off a solar panel about the size of a cigarette packet.
👌🏼👌🏼
Could you provide links, this could help many people! Thanks for the ideas.

We are also trying to think of solutions for this issue at the moment too. It is a tricky situation. We do have the option of spray foam, but would prefer to use a less toxic material.
It’s a tricky meter. Hehehe not considering the toxic material in our opinion close cell spray foam is the best. But isn’t mold also toxic? Hehehe in Brazil we have a saying for when we have no option that says something like “if you run the animal will get you but if you stay the animal will bite you” 😂😂 if you find any other good solution please let us know, as we only did for now half of the house 😊.
Your concern is well justified. The industry claims the final product off gases after initial application and becomes inert. I would tend to believe that in my own experience I've build with foam and currently foamed my crawlspace and soon my front entrance add on ceiling.
The problem occurs when the installer fails to mix side A and side B that leaves residual unprocessed chemicals behind...very problematic.
There is lots of TH-cam vids on foam nightmares.
A major concern not only with spray but all plastic foams is the emittance of toxic fumes on burning.
For that reason, ALL plastic insulation MUST be covered with a non flammable material.
Again, as with all container houses, you must realise the size of your living space is compact and any small infraction in design greatly amplifies the result of bad design.
Today's homes are constructed with composites such as TJI joists, glued beams, MDF, particle board etc. all emitting various chemicals that has the potential of affecting air quality and health.
Personally, I would choose foam, research the applicators' work history and understand the function of VENTILATION.
There are numerous building materials we take for granted that off gas when new, plastic insulation is only one of them.
Again understand the concept of air changes in the living space using ventilation either passive or active.
Good luck with your project.
Cheers,
N
THAT´S an very important point, too. Spray foam is nice and tidy but did anyone speak about that is still produces gas .... in an container house case - INSIDE your home!!!!
This is why I prefer the insulation outside. More space and less problem inside. And if it gets fire, the steel container wall will be a guarding shell.
We also like the out side insulation. For summer our outside insulation (wood) for sure will help a lot. But we are worried about winter 😨
Elastometric paint. Container home savior. AKA metal roofing paint. It will also take a tint and allow you to paint the exterior as well.
👌🏼
Hi guys. Just new to the whole small house idea and I am just learning about options. Containers seem like a good choice but I have a few questions. I think the cold weather and the condensation problem is fixed properly with expandable foam but what about hot weather? I would think you have humid and hot summers in Florianopolis. Will or does the container "heat up" during hot weather and what is your solution for that?
Obrigado e parabens pelo canal. Muito bom.
Insulating it properly and have the windows in the right places for cross ventilation helps a lot. For us solved the problem!! 👌🏼😊 if the weather is toooo hot I would somehow insulate the outside also. We will do that using wood strips. 👌🏼
Okay, in general their are two proven methods of preventing in-wall condensation in any structure.
Method #1 = Setup a breathable channel to allow air flow usually between the exterior siding and the insulation. The effectiveness of this method is variable depending on how well it is executed, you need to have enough air flow without having so much air flow that it starts to defeat the insulation. And of course their is always the issue with various critters, insects and otherwise (birds, rodents, etc . . .) setting up house in the air channel.
Method #2 = Seal everything up tight, tight, tight so that damp air can't get in and cause condensation. The most effective way of doing this is sprayed in closed cell foam done in an on-site application. The second most effective way of doing this is is to use closed cell foam panels and glue, calk, tape, etc . . . them in place to create an air tight seal. The effectiveness of this is dependent upon how good of a job one does in cutting the foam to exactly fit the application space and gluing it in place without creating any gaps.
For those considering this method with a container who are in North America there is actually a company that makes foam inserts that are formed to exactly fit the standardized container metal corrugations which you glue in place and then finish with standard flat panel foam board = www.insofast.com/products/shipping-container-insulation-panels.html I personally have no affiliation with this company other then having seen their product being used in a acquaintance's container house build that I was involved with and from what I have seen they work quite well.
Be aware though that not all glues and calks are "foam safe" so you do need to read the labels and get adhesives that are "foam safe" to bond the foam to the inside of the containers metal and then "foam safe" calking to calk any gaps in the seams. The spray foam is the best option but where it isn't available you can use the inserts and flat foam board panels with the correct adhesives to do nearly as good of a job for those choosing to go with the method #2.
We 100% agree with you!!
Sorry guys to say that, the insulation inside is the main mistake in my opinion.
Less room, more trouble. :(
The container basically is sealed, and air tight. Why don't you use this property?
If you put the insulation outside and make it air tight, as turbo 1889 mentioned in method #2, than it can not cause thermal bridge, so the wall inside of your container will be consistent temperatured with no condensation points and junctions.
This is the key: no thermal bridge = no condensation points where the moisture can precipitate.
Sorry for my English. I think you will understand what I mean.
I love your project.
Keep going Guys! :)
The problem is how to guarantee the internal part of the walls are air tide. Not in between that and the out side. I mean air tide in between the internal prt of the walls and the internal part of the house. As there is always humility on the inside the house.
Your are right! There is always humidity inside.
BUT! If your walls have no condensation points (those are usually colder than any other parts of the walls/building), the moisture can not precipitate.
(The ventillation gap between the wall and insulation just works against efficiency of the insulation. :( )
The meaning of "airtight" is very important -->not allowing air to escape or pass through.
It is not equal to there is no air inside the insulation!
(eg. EPS is a foam with lost of air inside ;) )
If the wind can not go through your insulation that is enough, it's okay.
The insulation can surround/contain any sealed air, but won't let the wind pass through.
I agree but disagree. Hehehe it’s a tough matter, and at one point we needed to make a decision and try it out. At least on this first part of the house we will give a try with ventilation. And let’s hope for the best!! 🤞🏼🤞🏼
I can't tell which of these two lovely people has the most beautiful hair.
😊😊not me for sure (Duca) 😂😂
Hello there, I just started to watch the container videos; de repente veo que los videos del bote ya estan disponibles.
Is great to see your dream come thru. Best of wishes, from Puerto Rico. Duca and Roberta thanks for inspire me.👍
Aha....now I get the spray paint before you installed the light gauge steel frame. Well done guys.
👌🏼😊😊
I enjoyed this video just as much. Keep up the great work. I am sure you will reach a viable solution.
Thanks a lot for the weekly support Travis!! It means a lot!!😊😊
Odd Life Crafting it is well deserved. Kudos to you both.
😍
A very smart couple unlike thousands of others
The only way to stop this is to insulate the OUTSIDE of the container. Closed cell spray foam is ideal. But you could cover the outside with aerated concrete, then paint it.
I was gonna recommend the same thing - insulate the outside. You can use thicker, less expensive insulation panels on the outside - I think there are even some that come with metal or wood or vinyl siding attached, so once installed they’re already weatherproof.
This will also save interior space, since you just need to finish the walls - you won’t need to insulate the interior walls since they’ll always be the same temperature as the exterior. You’d just need to use an exterior scheme that allows any moisture to dry to the outside.
Using vehicle under seal is a brilliant idea!
Just discovered your channel. Love your content and your honest and modest approach to tackling the problems that come up. BTW, I’ve been to your beautiful city of Florianapolis. My sister-in-law lives there. I really enjoyed my visit to Brazil.
Hi guys, always great to see your videos!
I'm thinking on insulate my container with spray foam but in the OUTSIDE of the container. After that, im going to cover the foam with wood (using a similar method that the one you are going to use... soldering the little pieces in the outside of the container to screw the wood).
The climate here is similar to yours, a little bit colder... im in Uruguay, in the border with Brasil.
What do you think? Foaming on the outside its a bad idea? :S
Regards!
Not a bad idea at all. We love the idea. Just be careful with water on the foam!!👌🏼😊
That is the point! :)
Never mind! The EPS and XPS are both closed cells, so the water can't go into them. ;)
👌🏼👌🏼
Thank you. You answered the questions that the pros would not.
Glad that somehow it was helpful
Very nice vlog, we in UAE suffering from high humidity and high temperatures it reach 48c.
I would suggest that you look for dehumidifier options some now are used on bathrooms and some are used on roofs ceiling.
Now as you are working ⚒ in new ideas then using dehumidifier in such case need some skills like ducting the roof.
Hi guys, I'm also using shipping containers for my house, but different design. I'll have 2x20ft and space between them 8meters and roof over it. This way I created a breaze way, so there always be a flow of air. That is the best way to deal with the condensation.
In your case as the containers are joined, you could use active ventilation on the ceiling, a simple 12 V exhaust fan would do the job, just use a solar panel to power it and have it on all the time. As the humid air rises, it'll get sucked out, even on a slowest setting, just to get it moving.
One the actual walls, you can use a small computer fans, just to create enough airflow, rather than relaying on passive container vents.
This way you'll have the air always moving behind the walls and limiting the chance of condensation.
Airflow is the word here :)
In regards to your wall clading-plywood unless heavily treated by chemicals, absorbs water and creates a mould problems.
And if you are worried about mould related illness, there is also a problem of off-gassing from glues, paints, etc... So again, not to have the ill air sitting around, active ventilation is way to go.
Hope that helps a bit.
Hi Michal. Thanks for the tip. We will think about it. 👌🏼
Hey guys! I live in Montreal-Canada, so I have access to spray foam insulation. Do you think is better if I go with that option??? And in that case, should I use steel framing or wood framing?? Thanks...
In our opinion definitely go with spray foam. About metal or wood I’m not sure. 😊
@@OddLifeCrafting Thanks a lot guys! You are by far the best channel and you are a beautiful couple too LOL ;)
Thanks so much for the support my friend!! 😊😊
Muito bom seu video explicativo sobre essa questão da condensação! Eu estou estudando as casas containers para ver se vale a pena, e todos esses detalhes sao de grande importancia!! parabens pelo projeto! Sou do Sul do BR tambem, no estado do Paraná e gostaria de saber onde voces estao em Floripa? eu sempre viajo de moto, assim que desse certo eu passaria dar uma olhada no projeto e voces! obrigado pelas dicas !
Valeu!! Que bom que foi útil o vídeo ficamos felizes em saber!! Sim a gente está em Floripa sim quando quiser passar pra uma visita é só avisar!! Valeu!!
Foi bem explicado
Uma verdadeira aula hehehe
Um ponto importante a ser estudado em qualquer obra em container
Pensarei MUITO bem nisso quando estiver contruindo a minha hehehe
Grato casal mais lindo do YT!!
😊😊valeu!! Que bom que gostasse!!
Nice videos guys! We are Brazilian s in Portugal rebuilding a ruin
You can buy some small plastic rings -about 3 or 4 cm across, which I did. Then I epoxied some plastic mosquito net across one side of them. Trimmed off the extra and filled the holes I drilled with the rings. No bugs and 5 years later they are still in place keeping out the bugs.
That's really good to know!!
Thanks very much for the info! I'm in a sub-tropical humid climate with lows around 40 Fahrenheit and highs around 95 Fahrenheit. A quick online search has recommended for my area to have walls minimum R2 and celling minimum R4.
If I can customize the height of my prefabricated container frame, what would be a good height to allow for the floor and celling insulations and still have a spacious feeling?
Very interesting research and conclusion to beat condensation 👍🏽
☺️
You two are so cute! I just found your channel thanks to Instagram. My name is Tibor, I am from Serbia but right now I live in Ireland and I am hoping to start building my shipping container house next year. Meanwhile I am happy to watch progress you make on yours. Chears
Thanks a lot!! We are really glad you are enjoying the videos!! Hope your future project goes well!!😊😊👌🏼💪🏼

Thank you so much for this 👍 SUBBED!
Welcome to our channel!
Hi, love the way you guys interact with each other.
I, too, am interested in building a shipping container home. Condensation is, I think, my biggest concern. I was thinking about using a sandwich panel which has good thermal properties
You should do what is the best to insulate your home and prevent condensation. Also you can go with slaked lime. I have them in my apartment in each room and hallway. You can hear them cracking and popping when there is moisture in the air. Make sure you have good ventilation of your home.
Anyway i hope i gave you guys great idea how to prevent moisture.
Hei guys, nice episode, good subject to talk about. I think the solution you came through is quite good but i would considered to use a Damp-proof membrane between the insulation and the wall boards (not sure if you will use plywood or plaster boards), if you cant find specific damp-proof membrane you can use normal plastic. This is really important to prevent the condensation to pass (While dosent dries with the ventilation) from the air gap you created to the plywood / plasterboards. if you need i can send you some pictures to show how to apply this membrane (is quite cheap and easy to place). Also make sure you have a good airflow on the gap, you need openings on top and on the bottom on the container)
👌🏼👌🏼 Thanks a lot for the tips!!
love their vibe

Hi Guys, great video on a topic that has plagued me for years in trying to find the "right" solution to the condensation issue. Our climate in south Florida is quite similar to your climate in southern Brazil. Please take some time to calculate the square foot area of ventilation. I am concerned that you may need to either add more vents (or install a powered exhaust fan).
Our Florida building code (has had this rule of thumb for years) for static ventilation for attics (i.e. soffit vents only - no ridge vents), found in section 1203.2 Attic Spaces: An airspace of not less than 1 inch (25 mm) shall be provided between the insulation and the roof sheathing. The net free ventilating area shall not be less than 1/150th of the area of the space ventilated.
So for a 40' container which has approximately 320 sq ft of ceiling (attic is the air gap between container and insulation), need 2.13 sq ft of free ventilation. But adding screen to the vents that is necessary to keep out those pesky bugs but also reduces the area of free ventilation of these vents.
Looking forward to next weeks video! Michael and Susy Kay
Thanks a lot for the support Susy!!😍😊
I don't know if it is adequate for your project, but maybe you could have insulation in the external faces of the container too, protecting the steel. The negative side is that you would lose the container aesthetic look probably ):
We will have some wooden shades on the outside as well 👌🏼👌🏼😊
Hey guys! So in the case that I decide to use spray foam insulation, I guess that I have to use a wood framing or I can still use steel framing?? Thanks, I really love this channel, is amazing how much info I am getting for you, thanks a lot!
I guess wouldn’t make a difference. But maybe would be good to talk to the company that will spray your house just to make sure. 😊👌🏼 oh and glad you are enjoying the videos!! 😁😁
Use wood. Doesn't conduct temp. Use metal only if the temp around it is the same temp.
Excellent explanation!
😊👌🏼
i know this video was a long time ago, but i'm wondering if y'all thought about insulating from the outside, and leaving the interior walls metal with your rubberized undercoating...... i know this adds an external finish layer that would be more expensive than the interior finish layer would be, but it avoids the condensation trap
Yep we thought about and we are actually good to have in three of the sides of the house
Two with wood and one with a vertical green wall (climbing threes). 😊👌🏼
Parabéns pelo projeto, estou acompanhando fielmente.
Valeu Gustavo!!
If it was me I would do 2x4 walls and ceiling with rockwool insulation then line the inside with vapor barrier (thick clear plastic) with all joints taped and for the floor rigid styrofoam covered with plywood. That way moist vapor doesn't reach a cold surface. A bathroom vent controlled by humidity would also be a good idea. Rockwool insulation isn't necessary but I like it because its easier to work with, you get a better R value for the thickness, drains water if it gets wet and it's not itchy.
😊😊
this will help me in the near future with my project,i learn new things from this chanel and from your awesome comment section, i search for a piece of land now and i want to build a house from two shipping containers and make one floor shipping home.If you have any advice to get my gf into this feel free to give me some ideas because she told me that she is not a sardine to stay in a metal box
Hahahahahq “she is not a sardine” that was a good one!!😂😂
Check out the "container of hope" project also and use heavy insulation (depends on min. max. temp. of your area) and controlled temperature exchanger ventilation. ;)
👌🏼👌🏼
Duca, you might be able to cut some foam strips the shape of the corrugations to flatten out the walls then apply your foam board over a level surface with no spaces behind I filled them with spray foam just a thought
Uhhh it seems easy to cut foam but it was actually harder than we thought. 😨
What do guys did to insulate the flor on your shipping container home??????
We didn’t. Hehe. We didn’t finish the floor yet
Great Epzode!
Thanks a lot!!😊
think I am going to use polystyrene backed giprock when I do my container. have you heard of that?
No. Never heard of.
Paint the roof white & be in the shade. Cooler. Tough problem.
👌🏼😊
Hi Duca and Roberta ,been waiting to see how you guys addressed the condensation problem it is a problem that doesn't seam to have a perfect solution an area of air movement between inner lining and steal sides of the container in mild climates should work and reducing humidity internally, keeping warm air away from cold steel keeps you thinking, in my case I decided to use a combination of foam panels and closed cell spray foam , when I bought one of my containers it had kitty litter in buckets inside,to absorb moisture I assume
Yep it’s actually a tricky matter. 😏
Let’s hope for the best!!🤞🏼🤞🏼
Question:. Why not insulate the outside of the container. That way the metal walls will not get cold and cause the walls to condensate the humidity in the air inside the container. To remove the excess humidity inside in warm weather use air flow through the house...in cold weather use a dehumidifier. If you insulated the outside with spray foam it would not off-gas to the inside of the container and you would not have to worry about toxic chemicals. You would also have better utilization of the inside space.
I have been considering to build my own container home using a lava rock and foamed concrete panels 1 foot thick on the walls and a 2 foot thick panels on the roof. This may seem like overkill . But I have a fairly inexpensive sourse of lava rock gravel (which is very light and porous). Combined with the foamed concrete which is areated by the foam is a good insulation. This is not structural concrete. Rather it is insulation and would have to be coated with stucco or at least sealed with a paint on concrete sealer. Instead of making the panels with this material, forms could be built around the container and and the forms filled with lava rock gravel and foamed concrete in layers....like making a casserole... .shovel in about 4 inches of the lava rock gravel at a time and pour in enough foamed concrete slurry to permeate the lava rock gravel and just cover the gravel....then add another layer of gravel to the casserole. The foamed concrete is acting as the bonding agent for the lava rock. All this can be done with hand tools and a cement mixer and a foam generator which you can build yourself from readily available plumbing parts very inexpensively. You would need an air compressor to create the foam in the foam generator. This is my idea for covering and insulating my container home, anyway....if any of this interest you could check into the advantages of insulating the outside of your container.
For sure it’s a solution but in our casa we built a deck on the roof already so it becomes impossible. 😏
There is a company called INSOFAST that makes Styrofoam insulated boards, that fit into the corrugation of the shipping containers.
Unfortunately they don’t sell in or to Brazil 😥
Fiber glass with aluminium foil is like a vapor barrier
Somewhere you said that your big problem was condensation.
Now if I understood correctly the humidity in the air where you live is around 80%.
In addition, you have a problem of condensation due to the temperature difference between the roof and walls of your container and the air outside.
If you open the windows, the humidity travels from the outside to the inside. So you basically have to remove this humidity from the interior of the container. In order to do this you have to condition the internal atmosphere of your container.
To do this you can turn on a dehumidifier; however, you have to close the windows or you will be dehumidifying the outside air as well.
After a while of running your dehumidifier your air will become stale with the windows closed, so you need to bring in fresh air.
If you open the windows, then again you have to recondition the outside air, and this is rather inefficient since you will have to run the dehumidifier again.
A better solution is to run an efficient ERV. It will help in bringing fresh air, but it will, also, help with humidity. An HRV will not do this!
Now, your ERV will run while your dehumidifier is off. It will bring in fresh air. It will take out stale air, and it will help in maintaining a lower level of humidity.
This will help with the condensation problem you alluded on your videos, and it will help with mold. By reducing air moisture, you reduce the chance of getting mold spore growth in the inside. If you put a simple vent, this will not work since it is not conditioning the air in the inside. It is only moving inside air to the outside, and when it stops running, the place where you installed it will suck in all of the outside air with all the humidity.
You cannot have it both ways. You either open your windows, and live with the moisture in the air, or you condition your inside air to avoid condensation.
If this was a house made with a breathing material, for example, red bricks, then other solutions might be possible, but your walls are made of iron, and there is no breathing going on besides the oxidation of the same. So, you have to think of alternate solutions and adapt.
We don’t have condensation problems we want to avoid having. And that only happens a couple days a year. And we don’t have 80% of humidity everyday. Other than that even do we have humid air. I prefer open windows and fresh air moving in and out.
Odd Life Crafting it sounds like you have determined your priorities. Best of luck
Sorry if I sounded rude. English is not my first language and sometimes it’s tough to understand explain my thoughts. To build the house without experience sometimes is tough then it seams. And even more when building something different to what it’s usually build where you live. In Brazil we don’t build framed house. It’s all masonry so we don’t even sell insulation. That means many of the solutions everyone is used to in different countries they are usually not available here. Bu as I always say sometimes you’ve got to do what you’ve got to do. And find a solution with what you have available. We might have expressed ourselves bad as we don’t really have condensation problems we are afraid it might happen. But until now we didn’t have any issues and this winter for our standards was pretty cold. The other thing is that in one point we need to make a decision so we can move on. So far we are happy with it. Thanks so much for trying to help. We really appreciate that, many of the solutions we are using on the house came from helpful people like you. Thanks a lot.
Odd Life Crafting no worries my friend.
I saw the hard time you guys were having, and I tried to provide an idea to help.
The manufacturer of the ERV is based in the USA, and it would not surprise me if they have a local distributor. So, send them an email, tell them about your situation, and maybe they can suggest something.

If you decide you don’t want it, that is ok too.
👌🏼 thanks a lot!!
I found a product/company called insofast that offers isolation panels that are made to perfectly match the container corregation
Thank you for this episode. Some very useful information to consider.
I know nothing, just asking😂 ok here goes......could a clay seal of some kind on the outside of the container, with regular insulation on the inside , and proper ventilation be the solution?
I guess it could but than we don’t see the point of having a shipping container. Just our opinion of course. 👌🏼😊
Aqui em Pelotas existe um dito popular que somos a segunda cidade mais úmida do mundo, perdendo somente para Londres 😒😒 preciso pensar nisso! Sigo acompanhando!
😨😨😨
I was confused the whole video because in the U.S. June is the end of Spring and the beginning of Summer.
Then I remembered you are in the southern hemisphere. I always think North America and South America is the same until I remember.
Hehehe no we are opposite 😊
Can you get the spray foam for your container home from neighboring stores??
Spraying roof waterproofing rubber paint (the one used to waterproof roofs of houses)is an excellent solution. Very long lasting,it is able to cover every nook and corner.Even small joints and minor cracks can be covered completely.
😉
Could you use pickup bed liner spray instead of closed cell foam?
Never heard of pickup bed liner. I don’t think we have in Brazil or maybe I don’t recognize the english name. Hehehe
One name is rhino liner. It's a liquid rubber paint that you apply to the bed of trucks that hardens. Protecting the bed from moisture and scratches.
Cool. Nice to know!!
Bedliner will offgas for a long time.
Im in the same position its hard to know which idea to go with i live in sunny Queensland Australia and humidity is very high here maybe we all should get together and get a metal box sand each try one of these ideas and seal it and monitor it like a worldwide experiments and post our videos and results
That would be great ☺️ as the weather varies a lot from one are to the other I think we should use different alternatives 😉
I am looking at doing it in North Queensland and the whole insulation issue can be very confusing with conflicting opinions.
Hello
You might want to look at automotive audio insulation. It is a peel and glue closed cell membrane 6mm thick.
👌🏼
do you mosquito net over your windows to keep out the bugs ?
Yep!! Mostly mosquitoes!😬😬
It seems to me that this resolution could do. But as bert skeleton says - you can consider whisper fans in addition. You will still have some condensation - at least in the morning on the windows, because the moisture will still be in the shipping container. The difference between inside and outside temperature is most significant just before dawn, and you can expect some on the only vulnerable place - the window glasses. So I would also recommend some ventilation.
For sure we will have on the windows. We believe it’s really hard no to have on such a small space with people inside. But lucky here is not that cold, even on the winter we can still open the windows to ventilate when it’s too humid inside. Or when we cook inside or take shower. In this way even if condensation happens on the window we can dry it out. 👌🏼👌🏼👌🏼 that’s our hope. Hehehehe
Since it's not that cold it will work - here in my place it is sometimes -20 (C) outside during the winter. But! Consider at least one in the bathroom :)))
Uhh that’s tough. On the bathroom we will have two windows one on each side and they are basically going to be opened 24h a day so we don’t think will be necessary. Even when is cold we close the bathroom door and open the windows. 👌🏼😊
;)))
from my understanding rock wool cant hold moisture and mold wont grow on it dont know if that helps
We are actually use PET wool for the walls. It’s cheaper and I think easier to work with. And also recycled material. 👌🏼
Another benefit you may want to consider is that rock wool is not combustible, whereas I believe PET wool may give off toxic fumes when exposed to flames.
I will check it out about how PET reacts to fire. 👌🏼
Really nice explanation 👌
Thanks for the feedback
i have been thinking of this as well. what about framing the inside with 2"x2" wood, and then hempcrete the walls, and then a lime plaster to finish. the walls will breathe and not sit on the inside steel....i think. i am questioning off gasing of using that rubberized undercoat...i have thought of that and also maybe polywall barrier, but still think of off gasing. ...anybody have input about the hempcrete idea?
Great video! Hog On
👌🏼💪🏼thanks a lot!!
Did you guys google vapor barrier foil?
And there is a company in Australia who make container homes. Maybe ask them, and if you want something like this spray insulation. How much does it cost to ship it to you from abroad?
We actually found this week a company in Brazil the makes this aluminum/eps insulation product. It seems really good so we ordered. 👌🏼😊
Deixa eu ver se entendi,,"meu ingles é basicão de mais".
Moro na Alemanha e aqui tenho coisas pro clima gelado, aqui eles cuidam muito da humidade,é como se fosse gas veneno e é muito grave mesmo !
Se eu colocar espuma expansiva e não deixar vão ente o conteiner e a espuma,não terei problemas ? O negócio então é não deixar espaços de ar ? E fora,o que devo fazer fora? Ou posdo deixar só com a pintura mesmo, eu não queria desfaçar o conteiner mas se eu tiver que fazer isso farei,só queria ter uma casa sem problemas de humidade. Obrigada meninos ,estou há meses tentando solucionar esse problema pra então decidir se faço ou não uma casa conteiner. 😘😘.
Isso mesmo. Se fizer uma camada grossa de espuma expansiva de celula fechada acho que não terás problema. Mas claro que o ideal é falar com alguém que já fez ai no clima dai. Essa é a opinião teoria de quem nunca construiu uma casa em um lugar tão frio. Espero ter ajudado. 😊👌🏼
What about using Aircrete? I'm thinking about building a workspace on my property using shipping container and i'm thinking of using Aircrete as an insulator on the outside of the container
We actually never heard of it. Will search about. We ar curious now!! Hehehe
Aircrete is an expanded concrete mix using foam as the expander. Its also called Foamcrete. I did some research and have come to the conclusion that it would not be suitable since it requires forms. Which in my opinion will increase cost
😏😏
Exaustor será que serveria para tira o ar quente para fora do contêiner?
Talvez sim. Dependendo de como fizer acredito. 👌🏼
Talvez sim. Dependendo de como fizer acredito. 👌🏼
Vocês chegaram a pensar no bidim? Não daria certo usar o bidim encostado na chapa e o isolamento com lã de vidro em seguida?
Pensamos em usar membrana hidrofuga. Mas por enquanto vamos fechar só o forro e resolvemos não usar. Mas impermeabilizamos o compensado pra garantir não ter problema e vamos usar isopor no forro. 👌🏼
i think I am going to use polystyrene sheets jointed with vapor barrier tape. its just a matter of keeping the moist air away from the metal.
👍🏻👍🏻 I think it’s a good idea
@@OddLifeCrafting the aluminium covered stuff you used looked great but I need to use something thicker. love your videos.
Maybe what you could do is get another solar panel and power a few of these small cheap thermoelectric dehumidifiers. They use like 22 watt. Drill some holes for pipes (from below) to the space between container roof and interior roof and have a little bit of air flow through it coming out of one of these dehumidfiers. It would basically blow warm dry air through the spaces. It could be a closed cycle with a line where any water could drip out.
You could also get an external humidity meter from these cheap weather stations to monitor the humidity as well.
Could be a solution but we don’t really like the idea of making holes on the roof. 😨😨 we are scared of having problems in a long term.
You could make an opening to the air gap from the inside, not the outside. Put one of those humidity sensors in there to see how humid it gets at night. That should give oyu a clue on whether the ventilation and slow temperature gradient works fine.
It’s an option bot a opening to the inside ai think will bring to much humidity. 😏
Everything understood
😊👌🏼
I'm assuming your living in a humid area similar to Hawaii? I am considering buying an empty lot on Big Island and considering a shipping container due to not having the money to build a house nor do I even really care for a house. I"m also a musician and one goal is to insulate it for sound reinforcement to record. Being your in Brazil I am assuming that yes you are in a humid zone/sub tropical? These insulating methods would then also could apply to a container in Hawaii? I'm looking at a small 20ft container as it could be all I could afford.
It’s humid where we live, but I’m not sure if it’s similar to Hawaii. I think this insulation would work in Hawaii as well. Good luck on your project ☺️
look at the "DOW Froth Pak 620"- Spray Foam Kit -- is this able to be shipped to you? a channel called "Off Grid Victory" for spray foam or a "Container Acre"
For us is almost impossible to buy anithing outside of Brazil. First with import taxes it doubles the price. Second we have lots of costumes restrictions unfortunally.
a solution will come-you are doing so great,I have enjoyed your journey
Thanks a lot my friend. Actually the hole discussion the vide generated made someone to send us a private message showing us an product we didn’t know about made in Brazil and we like a lot. we just ordered. It will arrive in 5 days!!😊
I knew a solution would show itself soon as you have an army of good people that are happy to help,I will wait for this episode. You have no idea how inspiring and positive your project is to us all.
I will begin my Texas container cabin project in the coming months. I have watched many " casa container"
projects in Brazil and you guys have some masterpieces down there. Mobily is one of my favorites,after ODD Life Crafting.
Thanks so much for the support Nick. It means a lot to us!! And good luck on your project!!👌🏼😊
Nao vi os outros videos, mas as casas nos EUA tem o Attic que é exatamente uma aera onde fica uma massa de ar de transição de temperatura, depois só precisa fazer o equilíbrio de massa de entrada e saida de ar, mas de qualquer forma seu telhado ja esta pronto, entao acho que não da mais pra recorrer a esse recurso
Ola, Venho seguindo a construção da sua casa com shipping containers faz um tempo. Realmente vocês precisam tomar cuidado nas próximas decisões a serem tomadas. Pra evitar condensação dentro de sua casa, vcs ja pensaram em colocar o insulation do lado de fora do shipping container e somente sheetrock dentro de casa. Vocês também podem colocar um ou dois exaustores proximo ao teto do shipping container para retirar boa parte da condensação. Boa sorte!
Boa noite. Na verdade por fora vamos ter um brise de madeira por fora o que ajuda. Mas somente para o calor para o frio não deve influenciar.
De qualquer maneira lhes desejo sucesso e que encontrem a melhor solução possível.
Muito obrigado pelo apoio Jessie!!😊👌🏼
Problem with rubber undercoating is you have to make sure if you are putting on Make sure its over paint and no rust is there ..The rust will still grow and bubble under the rubber coat ..Water will get in and you will have a rust pool growing faster
Canada many use spray foam and Open close vents with mesh for cross air And mini stoves or 1 big one
👌🏼👌🏼 thanks a lot for the tip!!
PS it may seem obvious but don't skip the extraction fan in the bathroom unless its go a window you can open.
We will have actually to window, one on the side of the sink and the other on the shower box.
