Eric THANK YOU! Your videos answer so many questions, this one was probably your most informative for me to date. I will be sharing this with the Barndo FB group. THANKS AGAIN, keep up the quality builds!!!
I could watch the foam expand all day
Greatly informative video...learning a lot from you all. Thanks for putting out these videos.
great video, great questions, great answers too. Thank You !!
Love your videos Eric! I appreciate how informative you are on all of your practices and tricks of the trade. You guys are all very skilled and knowledgeable, I hope to be lucky enough to call a barndo home some day. Thank you!
Thank You Texas Barndominiums for the video.Our last home was a barndominium.Our current home is a 50x60 metal barn.Hopefully we will get it spayed with close cell this year.
We slowing making our barn/home into barndominiun.Its an open concept thats for sure.
Very good video.
You should put a thermometer in a house and see what the difference in temperature is before and after the foam so you can show an example of the difference it makes.
I've been inside 2 different mental building sitting next to each other. One was fiberglass insulation and the other was closed cell foam.
There were 2 big shop fans full speed, and doors opened in the fiberglass insulated shop. And it was way hotter in there than it was in the foam insulated shop which had no fans and was all closed up. It was 97 and sunny that day. The foam shop actually felt like it was air-conditioned and it wasn't.
IM not building a barndominium just a remodeling job but you did help me understand foam insulation better.
This was so satisfying to watch!!
We want to see the closed cell!!!!
Very nice info. Thanks for sharing.
I really like your work and we NEED more videos please :)
Very informative video thanks!
I have questions about foam...
1. How do you rewire the home, fix plumbing if loaded with foam?
2. When renovating, can a wall with foam be changed?
3. I thought foam was a playground for termites? They dont eat it, but harder to see their penetration?
4. What is the projected life span? 100 yrs, 200 yrs?
5. If a fire happens is the byproduct toxic? Can say. Rowdy pet who digs, get ahold of it, is it toxic?
6. Is there a weight of the finished foam vs weight of fiberglass?
@@snowd123456789 You're an idiot
I worked for a builder for 10 years that used foam and fiberglass together. The studs were foamed where the sheetrock met the stud, basically the edge/corner and fiberglass installed over it. We had to tear out parts of walls on occasion and it was pretty aggravating. If the entire thing is foamed like they are doing here I'd imagine it would be a real pain in the ass. My opinion is you need to weigh the pros vs cons, I feel the pros outweigh the cons.
Very true , had to do a water remediation job in a trailer with foam . Spent 2 days removing minimal foam
I don't understand why some people feel they have to comment so negatively. A simple click of the mouse or swipe of the finger and "poof!", the content you don't like, understand or agree with is gone and you've just saved yourself heartache!! I enjoy your videos. I'm from Texas as well and I don't think the barndominium concept is for me but I'd never look down on anyone who likes them. I find that the processes used in your buildings are applicable whether for conventional framing or metal buildings of ANY use. With that said, you stated in this video that the closed cell ceiling foam and the painting of it would occur the next day. Did you by chance film that? I'm building a metal shop and I am considering closed cell foam throughout and would love to see how yours turned out. Thanks again for producing enjoyable content. (Must be a Texas thing, huh?!)
We didn't take any video of foam being painted, but we will try and do that soon. Thanks.
@@TexasBarndominiums Seeing the closed cell foam application and finished product would be awesome. Thanks.
Amen. All of these people are bashing foam, or bash open cell foam, when they have no clue what they are talking about. It's easy enough to do the research via google. People need to read some articles and educate themselves before acting like they know it all.
I disagree with that, I come to these videos for learning purposes, I like to see "everyone's" opinions... if a guy doesent like foam I'd like to know why, plus after reading all the comments atleast I know WHAT to search on Google to confirm what is true and what isnt
Best video I have seen for spray foam. Best questions and answers.. Thanks.
That stuff used to piss me off too my friend. Now what I do is hold back "at least" half of a subs pay until after I inspect and approve the job they did. And if I end up fixing anything they did wrong I charge a minimum of $250.00 fee that I deduct from what I owe them. I only had to do this once and all my subs got the message; now they do a final inspection themselves and I've had no problems ever since.
First of all, thanks for taking the time to do these videos. I plan on building a barndominium in the future and have actually visited your website a few times for ideas. Unfortunately I am in east Texas and out of your service area. Your videos have greatly increased my knowledge on the subject.
While the spray foam appears to be a great way to insulate, I do have a question that I cannot seem to find an answer for anywhere on the internet. I notice in this video that the foam is being applied directly over all wiring and piping in the walls. While pex piping is a great invention, it is still subject to needing repairs due failure in the future. Fittings are definitely a weak point. As for the wiring, I realize these are new homes and one would think that the owner will be completely satisfied by the quality I see that you guys build in. However, what happens when they realize that a room doesn't have lighting in all the places they might need it and want to install a new fixture or wall outlet? One would think that the pipes and wiring would be put in some type of conduit/raceway in order to allow for repairs/revisions in the future. Using the spray foam without either of these solutions or another suitable application it would appear that you would have to tear out sheet rock the full run of the wire/piping in order to repair/replace/revise.
So I guess my question is, when dealing with my contractor in the future, what is the feasibility of using conduit or a raceway for this application? Would it be something they would likely even consider doing?
Thanks again for the videos!
@@TexasBarndominiums Thanks for taking the time to reply.
Highly informative video. There is a discrepancy in what was stated. At 17:38 Clayton said that a closed cell was applied. At 17:57 Eric said that it was open cell on the walls and they would be back the next day to do closed cell on the roof.
What kind of paint do you use when you paint over the foam?
Really enjoy your channel, keep it up.
Hey guys, great stuff. I have used it “closed cell” in industry for many years. Regarding fire issues, there was a warehouse with a closed cell roof that caught fire in Illinois I believe. The closed cell foam roof was laying on top of the melted steel structure when the insurace folks arrived! The roof would not support combustion. Great material inside or out. Outside must be painted tho.
Hi there my husband and I love your channel, and all the informative info. We are about to start building a bar do in TX, tarrant county. I saw that you guys don’t do tarrant county, who would you recommend that would do the quality work that you do!?! Thanks so much!
The Munozs’
I'm really liking your videos, i'm learning a lot from them and gives me a lot to think about. I'm thinking about building a Barndo in North Florida, i wish you were in this state, i'd be giving you a call.
The best open cell spray foam is still no substitute for a vapor barrier. You MUST have a correctly applied vapor barrier with all
thru-envelope penetrations sealed with the appropriate products such as those made by Prosoco. No exterior wall on any building that I commission will be built without wood sheathing or a masonry wall. I do love the umbrella provided by those long roof overhangs.
So we need you guys in Utah! I would like a build...
Just for your info I was told by Uponor that the plastic fitting should not have spray foam applied to them, it causes a chemical reaction that will make them fail. It is OK to spray directly to the pex.
Eric have you checked out the Prodex 10mm metal building insulation? Looks like it gives us an R22 value in a very thin medium.
Great vid lots of info thanks
Great products
Very good video
Thank you
Great advice, now if you can Just do an HVAC video that would be very helpful. 😉
So is the attic a heated and cooled area too? He was talking about the a/c unit being in the same temp as the rooms. If not, would a radiant barrier help keep the attic temps closer to the living quarters?
Love all of your videos! Where do you source your glass garage doors? I'm having issues finding them.
@@TexasBarndominiums youre the man! Thanks, Brother.
@@TexasBarndominiums youre the man! Thanks, Brother.
I have seen recommendations to add reflective bubble insulation then firing strips on outside of steel frame before adding steel wall and or roof. This is supposed to reduce heat transfer from steel to inside of building. insulation is then added to interior. Building in Nevada so main concern is high temperatures with high sun exposure, rain and cold less of a concern.
If adding reflective bubble insulation in this fashion would foam insulation be recommended or an option? are there other options to improve solar radiant heat transfer?
Wish I could have worked for or with this guy at some point
Enjoy learning from these videos.
Here in Kentucky, wet climate, would it be better to utilize closed-cell everywhere (walls and ceiling)?
Wish you folks had a group here in Western Kentucky.
@@TexasBarndominiums
Thank you.
@Steve Sherman
Those are my concerns humidity, condensation, and mold in our climate (along the Ohio River).
you didn't mention the closed cell foam also adds additional structural support to the building. I would have put it everywhere as it increases sheer strength in the entire building.
I spoke to you one time before. I am building a small barndominium in Florida doing very similar to this. I have a small question, when putting my roof on a screw was put in and then removed leaving hole it was covered with silicone type material. Is this enough or should I ask builder to replace sheet it will be sprayed with close cell.
Hey great videos... I am looking to have a shop built, do you build in Haslet, Texas?
In our metal barndo we currently have the fiberglas installation installed by the guys who put up the building my question is ca we spray open cell over it.
What do you do if metal sheet has to be swapt with new one (damage,...)? And there is foam insulation
On another video I just watched you said nothing about closed cell for the roof. You said "use 5.5" inches on the roof and attic and 4" on walls" all open cell.
Will that foam cause the metal to sweat spraying it right onto it and that box around the stove pipe has to have fireproof insulation inside it don't it or not
How good is spray foam at keeping out insects? Does it help prevent termites, spiders, etc...?
Let’s say we get a hail storm that dents the metal. How do you replace the metal without pulling out all the foam?
Back charge them for time and materials ! Tell Leroy they make snips that hook up to your drills and they work awesome !
Work awesome but don't look awesome lol
Your so right !
what is the cost per square foot to build one of your barns?
Can you do a video that is more to the design phase? I am very interested in your truss design. Are these custom to every job or do you use a stock type and develop your clients home from them.
Why do you put wooden stud walls against the metal walls, is it just to get the 16" nailer, or is there an insulation or other reason?
Close cell vs open cell. A he I worked on was wood sheeting exterior on studs, drywall inside with insulation, not close cell. So pipe leaked, wood rotted, drywall needed to removed and the insulation was saturated. Wouldn't bit been better for a closed cell application to prevent water spreading and would it also insulate the pipes as well?
No. With closed cell if there's a leak you won't even know it and it will ruin everything. With open cell you will be able to see the leak earlier on that you would with closed cell. A quick google search will give you the info you are looking for.
is it flammable while in the container still or before it is sprayed on?
I just stumbled on your video and had a question on the overall barndominium concept. What is the overall construction costs compared to a stick built. Moving to OK
More lol
If done properly, like they were being built 20 years ago, it is cheaper than stick built. If it's mansions and houses packed with every bell and whistle like in these videos it's gonna cost more than a regular house, which is dumb.
THE FOAM SALESMAN SURE DID gloss over the price question like a slick politician. That stuff must be as expensive as gold!
It is NOT cheap, and he could have easily quoted it by the Drum Board coverage and did not. A good rule of thumb is $2.00 PSF and remember you get better (more) coverage with open cell than closed cell. Closed Cell is for roofs, walls and open cell is used mostly in attics. the initial R factor of a single spray is usually around 91-93% but a second spray to increase it to 98% is not really worth the extra cash outlay. Also remember that this system is approved for Attic Use of Closed Ventilation, (no ridge caps or eave windows)
@@anonimous2451 THANK YOU! Finally some info I can make good use of.
I did my house after Hurricane Harvey, the foam costed about $1500 more than fiberglass. Some things to also consider is the AC unit is in the attic, I had to add a whole house dehumidifier which was about another $1200. The cost of equipment and foam was paid back within the first year in savings on my electric bill.
@@unclefred1120 Hi, I am wondering if an attic fan or two might be an equatable and far less expensive replacement for the whole house dehumidifier???
Tribulation Prepper fans will circulate the air but not draw out the moisture. I’m in Houston Texas where the humidity is usually at 110%
Also you used open material asked I think 3 inches you get so many gaps everywhere little wholes and all that so basicly u will get more down side to what you payed and year wise last
Give LeRoy a raise he works hard
Cool video with great info. What about water vapor with the open cell in the walls? Why not used closed cell every where. May not be an issue in Texas but open cell in the walls in cold climates is a disaster.
You need some moisture to pass through if it's in the living space. Open cell also fills the hard to reach places better than closed. Closed should only be used for non-living areas.
Though closed-cell is more expensive, why not use it everywhere to get the best insulation factor?
Is he saying you would get mire efficiency out of fiberglass in an attic? 50-60% more?
Can you paint the closed foam a white color or does the foam show though a lighter color? Great video thanks for your time!
Any exposed spray foam should be painted. If not it becomes a fire hazard. Some jurisdictions require it to be painted or behind a fire barrier, like drywall.
How do you transfer the warranty house-to-house? 4:53
LMAO...YOU MAKE ME LAUGH!!
Why did you let him off the hook so easy on pricing...he still should have offered some type of price range.
Because no one looks at date video was posted. Giving out hard costs will mislead viewers years down the road.
I was thinking in terms of, on average you can expect to pay$?????
I enjoy watching your videos. Will be building a 60x100x20 steel building barn soon & love all the great ideas. Thanks!
Thank you.
We are going to build a barndominium on our ranch near Cisco. What we would like, would be to have a 2 story upper living quarters with the entire first floor serving as a shop with motor home and 4 car garage. Can you recommend any builder in this area? We are about 35-45 minutes from Abilene.
Don't know anyone out there. Sorry.
13:55 it goes on over the phonem?! That's some high tech foam! Lol that's what I heard
How do you change the medal siding in 20 years.
When they spray foam I would think that if they tried to make it as smooth as possible an level in the cavity it would be better, as you do concrete in the forms ,example some foam just touches the 2x8
I agree 100%. If you are going to do it...do it right. it should be even...
Eric,
So what total R Value are you getting on your typical finished exterior walls? If the 3.5 inches of foam works out to just under R-13 and seems a little low by today's standards, If you're using 5/8 Drywall that's roughly .5 R so any other insulation going into the wall systems when the exterior surface is metal? Not criticizing, just asking. Also any heat transfer through the perlins where there is less insulation being applied?
@@TexasBarndominiums Thanks for the info
Kevlar Foam
Do you use Dow Froth-Pak foam?
Eric : You haven't shown how you set up, uprights. Set or seal walls to concrete.
I assume the applicator was aiming for around 3.5", but if you look at the areas with 6" studs you can look down the wall and see countless spots where nearly the entire stud can be seen. This means there's no foam there, and no insulation.
Good prep work though.
isnt R-19 IBC standard country wide? 3x3.5 isnt R19
I would like to know how you seal up the role up doors.I paid overhead door to install doors an you can see day light an wind.?I called them back but I think they don!t care
Those are insulated doors
Any reason why they didn't fill up the wall cavities to the ends of the studs? It looks like there are about 3 or 4 inches of room left. I've seen videos in the past where they spray the foam proud of the studs and then shave it off flush with the stud.
@@TexasBarndominiums Thank you! Love your videos.
I like the idea of not wasting so much foam, what would it hurt to add 4" unfaced fiberglass over that or the blown in type they put the cloth mesh up and fill it up, and curious what the r value would be, finished wall
Apparently you or your foam installer doesn't know you should NOT spray foam on plastic pex fitting. Those fittings look like Wirsbo/Uponor. I was told by Uponor rep there can be a chemical reaction between the plastic fitting and the spray foam, the tube is OK. All you need to do is wrap the fittings with tape or something and you are good to spray. Hope those fittings are good at least till your warranty is up. More just for everyones info just wrap the fittings.
Can you get conventional, FHA, VA loans on this style construction?
Not FHA. I live in northeast OK and found out a barndominium is ineligible. The interest rate the first bank offered me was twice as high as what it should have been.
Hello Erick. Do you deduct your subs for all the bullshit they leave behind? Or do you just go to another sub next time you need that service? I’m still trying to figure this out with the subs here in Tucson Az.
How does the house “breath”?
How do you keep the moisture out and keep the windows from “sweating “?
What type of HVAC unit do you use?
houses aren't meant to "breathe". The better air seal the better! You have to manage the humidity and temperature inside with something like an ERV or HRV OR a whole house dehumidifier that takes in outside air and filters it.
You need SOME moisture. Open cell will allow it to breathe a little. For HVAC you need a fresh air vent installed.
One thing that I don’t understand about this company is “they say” to use the moisture barrier like a “zip board” on the exterior. But on some of their videos they put spray foam insulation directly onto the metal sheeting Like on this video. Can someone please help me understand? On a different video he said that the spray foam is an insulation and not a moisture barrier. But on this video seems as if he’s saying that it’s also acts as moisture barrier.
What is "Open cell or closed cell"?
Dancing around the costs. Must be expensive lol
It's really not. A friend of mine has a 20x40 shop sprayed with closed cell and he said it was about $2500. I'm sure a barndominium that size may cost a little more with having to cover everything and filling in all the spaces around windows and doors.
What kind of foam is it
How do you keep ants, in particular, fire ants out of the spray insulation. I use closed cell urethane insulation board to insulate my beehives and I can't keep the ants out of it no matter what I do. We are in the process of building a barndominium and initially wanted to go with closed cell spray foam but have great reservations with respect to ants getting into the foam insulation. Is the spray foam treated with a chemical to keep ants out of it?
@@TexasBarndominiums Thanks for replying. Could you elaborate more in detail about how the foam enclosures keep the ants out? Here in TN ants love to build nests in foam insulation. It seems like it is impossible to keep them out
Why did you use open cell on the exterior walls and closed cell on the ceiling?
why all wood? why not metal walls n roof? how hard do plumbing? get power in?
That is all done before spray application. Especially Attics. You do not want to wreck your R Value and incurr cost of extra re-spray due to missed something oopsy's. It just is not cost effective. Though this shows a wall spray, most people do NOT do wall sprays because it eats up all your space in the walls for future changes. Planning your wall vapor barriers and insulation ratings is better achieved using different methods. I have seen it done with the closed cell (less expansion rate) but IF you EVER want to make changes, you are pissing away your money on wall sprays.
Temperature gun will show the ambient temperature
So the question I have is, if closed cell gives a vapor barrier, then why use open cell if it doesn’t? Where is your vapor barrier with open cell?
It depends on if you’re applying the foam in a hot climate needing cooling or a cold climate needing heat.
Typically, it’s ideal to apply closed cell foam in colder climates needing heating. This is due to the closed cell acting as a vapor barrier, and not allowing the warmer air on the inside to find the cooler air on the outside wall and causing condensation.
With closed cell foam, it is vapor permeable and is suited to warmer climates needing more cooling, assuming that there is a WRB such as Tyvek applied correctly to the outside.
Hope this helps.
I'm waiting to see him use the foam "scrapper"
i got my foam guys to give me one.. lol.. that thing is pretty cool...
Why do you spray 2 lb on roof but not your walls ? Personally I always use 2lb everywhere in my homes. Little more money but a much better foam.
So, you've got a steel frame building. Why not steel interior walls instead of wood?
Steel studs are harder to deal with and more expensive. With wood it is easy to drill into them.
I notice that when this foam is applied it does not fill the entire stud cavity, is there a reason behind this? I have seen other applications where foam does fill cavity and someone comes behind applicator and has a long flexible knife and trims foam flush (relatively) to edges of stud cavities. Is either system more or less beneficial? Still waiting for TB to come to Wisconsin and build me a #62, LOL. Thanks Erik.
Mykel Hardin in Texas 2x4 exterior walls are still very common. Texas is a cooling climate. We’re wanting to lower indoor temp by 20°-30°. In the north they are raising the indoor temp majority of the year. Usually 50°-70°. That’s a higher delta T. Which requires a higher insulation value. Thats why 2x6 are used in the north.
so this is better then Rockwool
Assume you don’t use the same “fireplace guy” anymore.
I imagine the fireplace guy done it like he normally does it. Barndominiums are a total different ballgame than your typical house. They don't automatically know everything. Lol
How does the house "breath"? Doesn't foaming it seal it to where moisture/condensate form on windows, etc.?
@@DS-to1wf It's the job of your HVAC system to ventilate your house, so the air can be 'conditioned' to the desired state before it gets pushed throughout the house, including dehumidifying. Leaky houses may have been a thing decades ago, but these days with everything geared toward high efficiency, air tightness should be a priority, not just for comfort and efficiency, but also to prevent toxins, contaminants, bugs and rodents from infiltrating the envelop of the house. The only way air should enter your home is thru the HVAC system... of course, unless you open a door or window lol.
I am going through a foaming nightmare scenario in my own home remodel. His application temperature was too cold, his mix was off, and his pressure was too high so he put too much down, mixture was very inconsistent, awful smell, now a week later, some it feels like cotton candy and some of it feels like a 20lb foam. there is about 6 inches of cut off and He is having to pay another company, to remove it and re spray it.
following up behind contractors is standard practice these days....
I wouldnt have the wires nor the plumbing inside the foamed wall, for future repair reasons if nothing else. Wall mount the lot of it.
It's actually common practice and protects the wiring etc . You should not have a problem . Foam is not that hard to cut out anyway with the proper tool .
Open cell is fine for that, it's one of the advantages to using open cell for the walls. Wires can be pulled and pushed through a lot easier.
One sec I think my right ear is dirty let me unclog in real quick.
He's using the wrong caulk if thats for a fireplace vent.
what should it be? Mind to share?
@@driveramd12 we always had to use fire caulk (high heat) to meet code.
The caulk was being applied to the flashing, not the actual fireplace vent.
@@randomodbuild all good on the flashing only.. You are correct on that. Cheers
3:41 Guy on top of ladder, no bueno!
Good ol OSHA compliance right there LOL. I've been there myself
Why didn't you make the fireplace guys come back?
Usually the case, hope you found a new fireplace guy for the next job.
