Shipping Container Home Insulation Insofast Pros & Cons | Building a 20ft Shipping Container Home 

Using a high cube container gives you more height so ceiling insulation is not as much of a problem. Also putting a roof above the container of any type that creates an air space above will also help. I'd also say that if you're using this stuff, ABSOLUTELY get a ONE TRIP container. You DO NOT want to have to screw around with a beat up rusty dented container.

Run wires as you build the wall. I used this in my basement. I had inside and outside corners in my wall and I wired 20 amp circuits. No way I was running the Romex after I built the wall. I laid out the Romex along the wall before I built the wall. I then installed the first course, laid the Romex in the channel and fed it through my cut outs for the outlet boxes. Then I laid the second row and put network cables in this row. Then I finished out the rest of the courses. All very easy, just not the "normal" sequence.

Thermal bridging is a really important pro in favor of insofast. With a framed and sprayfoamed wall all of your studs will transmit heat, effectively lowering the r value of your wall. Insofast has no bridging so while the r value is not huge, it may perform better than higher r value walls with studs.

You were super nice and polite as to provide the cons in between. Thank you for this review. It helps a lot.

I can't express how happy I am you're reviewing this. I'm in Haiti. You probably heard of us. Earthquakes and Hurricanes? So I'm interested in alternatives homes to the traditional concrete. The issue? No contractor in the country is used to building like this and although we do have container buildings, they were installed by foreign NGOs who could fly in contractors. So I'm doing crazy research and intend on hiring professionals at each stage and instruct them on what I want. There's no huge temperature variations in Haiti (Think of always summer) so spray foam insulation is unheard of. I needed something to avoid my container to turn into little oven or cost a leg to keep cold. That looks like something I can do myself and the cost is reasonable.

Love the video and the comparison to other ways of doing this. As a newbie I’ve been leaning towards this system and your video was super helpful. Definitely mute that annoying watch from singing every 3 seconds from now on though 😂😂

Looks like I'm definitely going for Spray Foam insulation. Thanks for exploring this and sharing. Appreciate you brother

That helps a lot on what insulation I’m going to use on my shipping container house

Looking good. Be safe.

Thanks for the information I plan on having a 40 ft delivered here soon to my land I am going to fit it out for a temporary cabin while I am building my cabin to live in permanently Good information thanks again

It’s looking good keep up the great work

Appreciate how objective your videos are thanks.

Great comparison.

you are the man!! I am building my first container home over in New Zealand this Summer and this has answered a lot of my questions. I am a builder so will be framing it myself and getting someone in to spray! Your R ratings are crazy compared to ours lol.....here we only need R3.2 to meet code!! I will be watching all your videos over the next few weeks! Thanks again mate your a champ!! Damo

yeah looks like you will end up taking up some inches when getting ready to do the finished walling on the inside. Looking forward to seeing the future videos.

Glad i found this video, A friend of mine could'nt remember the name of this product ,Thanks bro.

One nice thing about imsofast os they contract with styrofoam plants across America so when you order they send the order to the closest plant to your location. That saves on shipping.

Wonderful video for sure !!!!

Thank you!!!

Hello - Love your thoughts on this and would agree with it being more useful for a 40' build. Have you thought of running a RESCheck for UA Value with using continuous insulation like this? Great selling point and will allow you to use less R value when you have continuous insulation withouth thermal bridges of frames than insulation.

Hearing that this product provides r13 and r9 for walls and ceiling I think you said... I’m wondering what you’d say to using them on a project in Thunder Bay Canada where it gets to -20°c (that’s -4°) and below every single winter. I love the idea but I think that cold, I’ll just spray foam.

keep it going

For some reason I'm not sold on this as I really doubt there aren't any air pockets left = which will give space for hidden condensation. Slight imperfection in the steel and you have air between teh insulation and the steel wall. What is your experience ?

I ddnt understand anything you said..i was focused on your cuteness 😊😉

Do you need worry much about condensation with Insofast? I am up in Michigan and worried about condensation from the high & low temps. Thanks for the info!

Is this video for contractors or for home DIYers. I love the pros and cons but I'd say most people watching are all home DIYers. Stay safe brother.

If I were building a bigger container setup such as a few 40 footers attached together, would you recommend this system? There will be numerous cutouts and need for structural supports and this would be in northern GA.

I’m also a DIYer. The correct answer is certified and tested Closed Cell Sprayed foam insulation. The reason why that’s the correct answer is because of temperature gradients causing the danger known as condensation on your metal walls specifically between the metal and the internal wall… where you erect your framing and insulation panels. Cause metal and water doesn’t mix… cause you know… rust. The solution is spraying closed cell spray foam on the metal to stop condensation in its tracks. Then the framing of the floor and walls is done within the foam envelope you sprayed. Condensation eliminated. Only standard problems remain that you have left to deal with would be stuff like air ventilation which is easy to move fresh air around your living space. An alternative to sprayed foam insulation that is slightly less good but equally flame retardant and water proof and air tight would be Sprayed cork insulation. Cork is the stuff from wine bottles. Cork is green and sustainable to harvest.

We just ordered a couple of 20’ one trip containers to use as storage rooms. Not sure when they arrive. We live in Northern California where it can get pretty hot in the summer months. What would you recommend for a thin but effective insulation for storage use?

Fabulous presentation. Some comments this time are really frustrating. It's like they haven't listened to a word you said. You're a patient man.

Well that was interesting. Wish someone would a vid for foundation and insulation in the south where freeze happens once in a hundred years.

Really happy I found your channel. I am in the process of making a Retail clothing store out of 3 40ft containers. Would this Insulation work well with my idea?

Would it work better to use the InSoFast on the walls and frame the ceiling? That would allow you to run your wiring overhead and only using the raceways to go down the wall. It would also allow you to get a higher R value on the ceiling. And what are the plans for insulating the floor?

Code min of continuous (thermally broken) insulation levels vs between the bridges. Maybe it'll pass somewhere. But applied exterior with commercial taper and membrane on top and an eifs, this could fulfill someone's aesthetic

“Framing” & insulation 🤔 can I wall mount anything to this “framing” or is it more like attempting to wall mount on Plaster?

First thing I said was , what happened to the beginning? lol. Great video , cool product but I’m guessing the biggest disappointment is R value. I would rather frame and spray instead of add other insulation on top or do outside as well. 🤷🏻‍♀️😐

is it mold resistant? bc moisture builds bwt container. thanks

Hey! Great info here thanks! Are you planning on getting air change test? 'Blower door' test? I'm curious on how air tight the system can be.

You should have mentioned that this needs to be covered with a fire barrier like gwb, FRP panelling or painted with intumescent paint by code.

How does it stand to condensation that seems to be a nice flaw with shipping containers

With pets how does acoustic (sound proofing) rubber work with foam? Pets can be loud. I saw foam wrap on outside for underground. Still curious...

I am part of a project that uses stainless steel spray foam insulated containers made for refrigeration that cost $5k new. Seems to a better option than your used container plus all this material and labor.

Great system but what exactly is the space left internally after installed? Most container internal widths seem to be 7' 8.5" (2350mm) so taking away 2" either side leaves 7' 4.5" but how much does the 3/8" adhesive squeeze down to?

Hi! Great. I've been researching about Insofast. I like your video, very helpful. Is there ny possibility of talking to you about my project? I have a Florida room that needs insulation, and I don't want to spend too much money. Thanks, Jar

Maybe put the foam insulation in before the windows are installed. Can just cut out the windows with the foam attached. Dont have to cut down all those panels before installing then.

have you used Prodex on a shipping container or any other build to give pros and cons between Prodex and in-so-fast. thanks

hello sir! it would be nice to hear your opinion on what kind of insulation you recommend for places that are very cold in the winter and hot in the summer...thanks :)

Удачи тебе, привет из Украины=)

Here's a Con you did not mention w/Insofast. In the air gap space between metal skin and insulation (in humid climates and particularly in Winter) condensate water will form on inside walls and ceiling. The same water will run down walls to the floor. To avoid this, suppose you could run a dehumidifier.

A pity you didn’t show the electrical race-way’s you mentioned. Thinking of using Inso-fast with Sip’s on top to get a strong wall with the necesarry R value for my container.

Damn, I was excited for this product too, until I looked at my R-Value building codes for Washington State. InSoFast is a no go from what I understand. Let me know if I'm wrong or if there's a way to still use it and meet the R-value requirements as I want to build a shipping container house still.

Why not put the insulation on the outside and then do conduit electrical and plumbing on the inside and under the container? I’ve always wondered why people frame a container since that kind of removes the advantage of the prebuilt box.

What if you just used this on the roof and exterior? 🤔 I like the container wall look inside.

Hey! I am thinking about hemp wool insulation instead of foam spray and other types. Because it says that hemp is protected against moulds and bacteria, does not contain harmful substances and so on, so on. What is Your opinion about that?

I'm a lead builder of container houses. We have been using insofast for a few months. Do you have any feedback on the longevity of the PL over time and high outside temps? We build in Las Vegas

So the weight of the drywall is solely dependent on the adhesive holding the Insofast to the deck?

Could you use them on the exterior?

@containing Luxury Long time subscriber, love your videos. Do you have any suggestions for exterior insulation for a container home trailer? I really like the idea of keeping the interior walls as metal (using magnets to hang pictures and not losing living space). The product your reviewing looks like it could fit the bill, but would maybe need a good exterior siding? Thanks in advance and keep up the good work!

How can someone Insulate a container and keep moisture forming between the foam and metal leading to mold that you cant get to.

Is this stuff very flammable?

Is this good for a 40ft container if I want to do a cafe from it

In a cold or damp environment wouldn't spray foam need to be the default method? I was looking into diy spray foam- choked on the cost! Rethinking if I should even try this project. Is it possible to find a hybrid approach to be less expensive with a higher R value for snow country? Thinner spray foam layer, adding foam board over? Perhaps with 2x6 studs?

How much did u need to complete the container and how big was the container?

How do you move a finished single container house? People tell me it has to be empty to move my container. Any ideas?

Since you are playing with Styrofoam, just use ICF blocks to build the house - about the same money you spend on container + insofast, but much better insulation and hurricane proof !

What if you do Romex as you install the panels

Can you frame a shipping container without making holes into the steel? Would it be possible to make metal frame that fit snug into every corner end to end so it doesn't shift about?

How well would this work in Wisconsin with all 4 seasons?

It looks like they could improve by making specific 20ft and 40ft precut insulation kits. Would avoid a lot of time by the DIYer rather than the manufacturer which should be the whole purpose of Insofast.

Would loooooved to see more of the "work" with voice over instead of standing monologue. Missing the teaching moments. I know that involves more onsite filming and more effort editing. but other then that I love the in-depth breakdowns! I would TOTALLY HIRE YALL TO BUILD MY PLACE!

EPS is R-3.8 vs R-7 for closed-cell spray foam.

Thanks again! #MyFavChannel

I used these at work last week. Why did they space the vertical "studs" at 22" but the ceiling studs are 16 on center? It makes no sense

Moisture issues between foam and container sides?

Me gusta MUCHO. PERO HABLAS TAMBIÉN MUCHO....👍👍👍

Is insofast better than spray foam when it comes to condensation?

you just became in so fast public enemy # 1 ....😲🤣🤣🤣

Would it make more sense to use this on the outside (if the system allows you to do so) - for instance, if you were going to put on a exterior siding material.

Me after watching this video: "Okay In So Fast.....it's a no from me"

How can I link you up

With today's technology and advancements in insulation, why is Insofast so stone age on the r values? They really should be looking at a better r value for owners in northern and southern climates. Very few places can settle for the r values u stated.

Price and system make more sense if you don't have to panel or drywall over it.

$1400 for spray foam... uhh no, he was giving you friend price because its 2k setup price in most of the country. I got $6,500 to $12,200 quotes from sprayfoam places for a 40' highcube here in OK.

Also Higher R value means less heating an cooling cost over all. What you really mean to say is you didn’t wanna do the labor hours to benefit your customer

Shipping container ... what is the width of the average prison cell?

Whats the r value of this kind of isolation?

When is the next one

Would it be smarter to have the electrician come in first before you lay the panels down for a do it yourselfer?

Get the BEST freakin stove/oven you can get your hands on and install it in that unit! Do it please por favor

Put it on outside it would will work save room if ur the carpenter u claim you’ll figure out how to finish inside

The problem with spray foam and Polystyrene is that they are both very toxic.

Spray foam would be cheaper.

way to go Bro!! I just bought a home in Arlington Tx. and am doing research on storm proofing my pad. Its about time us brothers show you alll white folks how to protect you home. I love it!!

You forgot another con. It's not closed cell foam.

I called to talk to them and the lady on the phone was extremely RUDE ... decided to frame and spray foam

Please mute your watch or devices while filming. Then check your messages in between cuts because obviously your a busy guy lol. Nice product, nice video.

Is it me or does it look and feel a bit claustrophobic?

Eat the bugs guy.

I really will like to tell you my story i been trying since the pass 4 yrs but contact me to tell you more.
