    Goid stuff here. I am learning a ton. The flaw that I see from your hybrid system, if I listened correctly, was the double vapor barrier on the exterior wall. Because the closed cell created the vapor barrier on the exterior and the 6 mil was applied interior, it didn't allow for the cavity to breathe. The batt became the sponge in the dew point zone and it just went down hill from there. I love the idea of CCSF from the application and function stand points. The problem is being of the interior vapor land you have to switch your mindset and knowledge to how it's done down south. Thank you tor sharing your knowledge and experience. I will definitely be watching you guys more.

    • @MrPostFrame
      @MrPostFrame  Рік тому +2

      Sorry I wasn't clear. The original problem was the thickness of the CCSF. The spray foamer we used didn't evenly distribute the foam. There were areas where it wasn't even an 1" thick. Which didn't give us the exterior vapor barrier and caused areas of frost build up. We now do 3" of closed cell on all our builds.

    I've watched your channel for awhile, really the whole thing from start to now and that particular insulation install and issues you had. So glad you did this video and shared on Pole Barn home builds with insulation and the right way to do it. We did insulation about 10 years ago in our stick built home and loved it! It was an older leaky home and I was concerned with the spray foam until I saw it go up and the results that first cold , cold winter day. Spray foam was relatively new at the time and I just wondered about it. We actually almost built a pole Barn home a few years ago and decided not to because of cost for us.. I know we most likely would have had similar issues, but you have really been great at educating people on this. You had an issue no one would have, could have thought of, and it just helps people who built Pole Barn homes and what one needs to think about not cutting corners with any insulation job on any build. Thanks for being a Great Contractor, Builder and teacher as well!

We have been advocating for many years on how to select a contractor with proper credentials, knowledge and experience in the insulation industry. A good reference for people looking to have spray foam installed is thru the SPFA, where Master Certified spray foam insulation installers can be searched for by state. Another subject that I feel needs more attention would be energy savings comparisons of traditional fibrous compared to spray foam. Thanks for making these videos.

A shout out to Hinderliter Geotechnical Engineering in Oklahoma, if you need residential work done they were very nice to work with, over the phone and in person. They even gave me some core samples to keep and display. Oh and if you are wondering why we had it done, we moved a lot of dirt and got very mixed answers about the soil and cracking foundations so we just decided to go to the professionals.

    I have a 36x48 post frame I put up last year, and when doing so I made sure to have house wrap put on it anticipating spray foam. I didn't want the foam adhering directly to the steel for future panel replacement issues, etc. Anyway, I got around to pricing spray foam, and 3" is coming in at $11,900 (walls only). To get a comparison, I decided to look into a DIY version of flash and bat: 1.5" pink foam all around (including behind the posts because it's the same thickness as the girts) and R19 of post-frame specific fiberglass bats that come with a plastic face. This combination will get me R26.5, and cost me a couple dollars short of $5,000. No, this doesn't account for cans of foam to seal the panels together, but at almost $7,000 in savings, I think I can more than cover that expense and still come out ahead.
    I love the idea of spray foam, but it has absolutely turned into a racket. They are charging whatever they want and getting away with it, part of the current building craze were people are just going insane and paying anything in the process. I will look into the installation spec you mentioned about making sure the vapor barriers are in the right location and all that, but so far I just can't see any justifiable reason to tell people to go with spray foam. If you put your panels together with canned foam and tape those joints, you're going to end up with the same sealing effect you would get with spray. Sure, it will take a little more effort to make sure you're doing it right, but again... At $7,000 savings, there's a lot of incentive to take your time and mind the details.
    Your mileage may vary, but I certainly don't think this option should end up at the bottom of the list.

      I'm building a 1800sqft shop in side one of my pole barns and I've decided to use 10m poly on the ceiling and walls. Walls are getting 3" thick foam, ceiling will be blown in. The building was built in the late 70s and will be a shop. I am comfortable working in 60* no problem however what heat or ac I do put into it I would like to keep in. 1/2" osb throughout the inside.
      Still need to figure out where my poly needs to go on walls. Thinking right over purlons and posts then put the foam board in. All electrical and air will be in conduit on outside of wall/ceiling.

  • @paulwackerla6330

    Great breakdown of options. I agree with you that closed cell spray foam is worth the extra cost and it has so many advantages, like keeping insects out, sealing out air infiltration, increased structural, and the labor is included. Also, since you have a tight structure, your utility cost will be much less. Using fiberglass is a terrible option, as air infiltration is a real problem, which has a huge cost in the size and use of your HVAC system. I think if you take into account the HVAC savings, that spray foam is very competitive. It's better to spend more up front and save for many years to come.

    Excellent video! You can definitely tell that you and Emily really care about your viewers, to take the time to do this. This was very helpful. Kyles video on the Rockwool/Majrex was good too. I have concerns about spray foam because there are so many people out there doing it that really don't know what they are doing. Also I worry about the VOC off gassing which I understand can occur for a couple of years. Was wondering if you could comment a little more on exactly what caused the problem in your house. Was it a bad spray foam job, or was it the addition of the batts or both?

    • @MrPostFrame

      Started with a horrible spray foam job that didn’t even provide a vapor barrier in some areas. Then the batt insulation soaked up the water.

    Hey Paul, i bought a kit from World wide steel buildings, the engineered plans called for a complete envelope of 1” foam board to attach to the exterior of my girts, then used 2” roofing screws to attach the metal panels over the foamboard to the girts. So that provided a good thermal break to my steel structure, then i followed up with 3.5” of open cell to the cavity to completely air seal. Kind of a hybrid system not sure what the actual Rvalue achieved is but it was definitely different.

    @tedpereboom6983 Рік тому +1

    Sorry to hear of your leak. I like the use of a liquid applied membrane, such as Prosoco Cat 5 on the outside so you would need a plywood type material on the outside of your lumber and is now considered the Inside of the house. After applying the membrane then you can put your Rockwool on top/outside of that so it all butts together making no thermal bridging and can be on roof and walls continuous. Your metal goes on top of the Rockwool and you end up with two layers of drainage, the metal and membrane. If you left your wall open in the "Perfect Wall" type house you would see if any leaks are coming in and very near the source. You can investigate by not having to rip things but instead unscrew your metal on the outside. Any leakage also can dry from the inside and outside.

    • @AndirHon
      @AndirHon 5 місяців тому

      It's because closed cell foam creates a vapor barrier. Anything inside the closed cell foam is inside the house and conditioned. If you put another barrier on top of that and ANY cold air gets in that space it will create moisture inside the wall via condensation. (Think of a cold glass of water on your table.) Normally when someone seals up using plastic barriers it's not as air tight as the closed cell foam so it's easier for moist air to get between these two systems from the inside of the house. Drywall also acts like a low grade vapor barrier. The insulation added inside the closed cell foam will soak up and hold that moisture and cause problems. His issue was that he had a poor installer that did not get good coverage on the spray foam and some cold air was getting into that space and since it was filled with insulation it was trapping that cold air and moisture from the living space.

I am unable to address it easily becaue the service entrance and utilities are on both sides of that wall. I am hoping that it is not going to be a problem. It did have some moisture form in the bats when the building was at 80% humidity while doing floor polishing and the temperature was below 0 and very windy. The supper fine snow and high winds showed every leak in the building and high humidity cause condensation in those closed areas but seemed to go away once the humidity was reduced.

      If you use zip sheathing you are fine to use fiberglass and a vapor barrier. Zip is a weather barrier not a vapor barrier.

    How loud is it when it is pouring down outside? I was told that closed cell is good for structure rigidity/water resistant but noisy verses the open cell foam quieter but soaks up any water leaks. What is your thought of doing 2" closed cell and then either some open cell on top or 3.5" of rockwool in the 2x6 wall. Climate zone 3 is where I am building.

    Will I have a problem? I have property in building zone 5, I plan to build a post frame, I plan on 4.5" rigid polyiso board to the exterior of the sheathing and rock wool between the commercial style girts, I just learned today my vapor barrier has to be on the inside? Am I going to have a river of water falling between my foam and wool?

    • @MrPostFrame
      @MrPostFrame  Рік тому +1

      Vapor barrier on interior of wall in zone 5 is correct. My question is how much is it a square foot for the polyiso board and how much for the rock wool per square foot.
      Polyiso is a closed cell material so at 4.5”so you should be getting a vapor barrier. it’s hard to say what would happen if you then add another insulation on top of this changing where the vapor barrier is located in the wall system.
      I pay $4.50 sq/ft for 3”s of closed cell spray foam installed and that’s all that needs to be done and I can rest knowing there will be no problems. My guess is by the time you pay for both products and for install you are at least $4.50 a sq/ft.

    Hey Paul, quick question. My wife and I are doing a barndo in Central Florida between Lakeland and Orlando. General Steel is the one that will be providing our structure. They gave me a document for arguing against spray foam on barndos. I am a huge fan of spray foam though. I can send it to you if you like so you can look at it. What is your opinion of doing closed cell on the exterior walls and then R38 batting for the roof? Have you heard of anyone doing that before or just do the entire thing in closed cell spray foam? Thanks!

  • @christopherhaak9824
    @christopherhaak9824 Рік тому

    I think that one of the things just touched on is climate zone. If you're building in the south, the vapor barrier should be on the outside, which actually favors a post frame with barrier sheathing that is taped. In fact, it's the only way to go. Then insulation options are wide open, but you must have a continuous exterior barrier. You can even blow your walls with cellulose or fiberglass with the interior fabric under the girts. As you noted, highly zone dependant, and it just happens that you and Kyle are in northern heating climates.

    To be clear, the problem you ran into was due to using both spray foam and bats with no backing? OR also said using dissimilar materials.
    Also, what did y’all do on your roof?

    • @MrPostFrame
      @MrPostFrame  Місяць тому

      The main problem was that the spray foam installer did a bad job and then said to add fiberglass for more r-value. Closed cell spray foam becomes a vapor barrier at 2”. Verify this with the manufacturer of foam you use because it can vary. In our build zone the vapor barrier needs to be on the warm side of the wall and by adding additional insulation you are moving the vapor barrier to the interior of the wall which changes the science behind it. This lowers the dew point and under certain conditions can create condensation in the wall. There is a formula for this type of wall on sprayfoam.org It talks about how much closed cell sprayfoam to use and how much other insulation to use based of the target r-value. There is fine print that says to add 3/4”-1.5” of closed cell to avoid condensation. You best bet is to pick an insulation and do it well. Mixing and matching doesn’t always work. Spray Jones UA-cam channel is an excellent resource and he has become a good friend of mine. He has detailed videos backed up with facts.

    Go rockwool! Its easy to do and the sound deading is amazing. It doesnt wick moisture so if somehow the floor floods it wont suck that water up into the walls. Its not as efficient long term as spray foam but it is a very close second due to initial cost and if you plan on working in your shop the sound deading is hard to beat!

    @X-22CamRS-SS-RS 2 місяці тому

    Thanks for all the great info. I think your moisture problem in the wall is not from the fiberglass insulation. Fiberglass allows air to flow thru it so it is not a vapor barrier nor can it change where your vapor barrier is. You said that you used closed cell spray foam on the exterior of the wall that is equal to a vapor barrier. By
    installing a 6 mil vapor barrier on the warm side of the wall you have installed 2 vapor barriers and are trapping the moisture inside the wall. I think if you are in
    a cold climate where the vapor barrier is on the inside, you should spray foam from the outside of the building if you are not going to fill the wall cavity. Then you can allow your wall to breath to the outside like it is supposed to.

  • @conradcoolerfiend
    @conradcoolerfiend Рік тому +4

    a big benefit you didnt cover enough with closed cell spray foam is the air tightness its going to give you. That is going to translate into a major reduction in air leakiness and therefore heating/cooling costs for the lifetime of the structure. Air tightness regulations are increasing in building codes as regulators require tighter and tighter homes as a part of energy reduction. Lots of areas are bringing in mandatory blower door tests to make sure you pass those benchmarks. In standard house construction, best air tightness is being done with the sheathing and seam taping (zip system, etc) but on a post frame house without sheathing, that is not an option. so the spray foam is really the only way to get a super tight house IMO.

    Very informative. How about using structural insulated panels (SIP)? I'm building a geodesic dome home and had one spray foam company about five years ago come over to give me a bid and they quoited me 135k. I didn't do the price per square foot breakdown but knew that it was way more than I was willing to spend. It was also very discouraging getting a price quoit like that. They said that the price was $3.50 per square foot for two and a half inches thick but I'm pretty sure the guy just tossed out a very high number and didn't use the $3.50 per square foot price. Most of the outside of my house is wrapped with Ice and Water Shield. I live in WA in zone 3 (the yellow zone on that map you shared in this video). I'm now thinking of using Rockwool after I saw RR Buildings video. I'm thinking of getting some more estimates in terms of a price based on square foot and see what they charge now. Question: The exterior of my house is mostly wrapped with ice and water shield. If I use spray foam, will the roof sheathing rot due to trapped moisture between the ice and water shield and spray foam from the changing seasons where it freezes in the winter and is warm in the summer? Also, I've heard that SIP's have an issue with that as well when you use ice and water shield.

    Paul or anyone reading this, if anyone knowledgeable could answer that'd be great. I am in the research / land buying stage of building a home for my parents. We are obviously trying to get the most equity we can for our buck, and I'm somewhat handy, but not sure I'm willing at this time to do a majority of the project DIY.
    There is a local company that builds buildings (shells). They do post frame for about $40/sq, and traditional framing with footer for about $80/sq. They typically do post frame for garages and workshops, and traditional framing with footer for homes. They say the post frame buildings will be cold around the edge of the slab because there is no footer. How is this typically dealt with for people building a post frame home?
    Second question is: since I may want to hire out a lot of the job for time and quality sake, but still get a lot of bang for our buck, how would you recommend going about the whole process? Should we build post frame as owner/builder / gc the project ourselves, while subbing out the work? We'd love to have a some professional input in the design and planning aspect. I'd like to have a beautiful home in the end, and not something that looks like an amateur (i.e. me) designed and built the thing. I guess I'm just looking for a little guidance on how to properly lead this project, and how to find the right people in my area that I can hire to do a great job with their respective parts of the project.
    If I knew someone like Paul or Kyle in my area to just hire to build the house - or to guide me in the process - I might just do that. (located about an hour from Wichita KS by the way, not in the KC area)

    The one thing I'll never understand about this build, considering all the effort you put in, is how there was no substantial framing or sheathing between the cold metal exterior siding and the spray foam. You house wrapped the post frame, then sprayed foam directly on the house wrap, which was equivalent to spraying foam on nothing more than a flexible sheet pulled taut between widely spaced columns. The spray foam is attached to nothing but itself over so much area, no structural integrity, it's going to move and flex and crack and fall apart and let air and moisture in. I'll never understand why you did it that way when you put so much effort and detail into everything else. And please don't take this as negativity or armchair criticism. It's a genuine question.

I would have never been able to heat it or stay in business if it wasn't for closed cell spray foam. It's an auto repair shop so I do welding, grinding and other types of fire hazard work. A local roofing contractor said I couldn't weld here because my shop would burst into flames... I've never had a problem. I had a extra walk in door put in and took a propane torch to the wall cut out until the foam and wood were both in flames, as soon as I pulled the torch away the foam extinguished & the wood kept burning. As far as I'm concerned: flash point of foam
