Thanks for stopping by our channel! We are self building our family of 5 a post frame barndominium in Iowa along with the life we’ve always dreamed of.
The goal of our channel is to inspire others to build their dream by providing education on construction and an in depth look at how we’ve gotten to this place.

Thank you for the vid very informative
We didn't put a vapor barrier under the foam in our house or garage. We have at least 5" of 3/4" clean rock and the soil around here is well drained. Besides, we only get less than 20" of precipitation annually. In 7 years I've never seen any sign of moisture. While building, if it did rain, it didn't slow progress as there's no mud to deal with. I have walked around in freshly dug soil during rain and not gotten my shoes muddy.
Excelente trabajo felicidades 👏 👍 saludos desde chile 👊 👌🏻 👏
Thanks its very interesting how these are built in USA we dont have that in the UK. Its good to watch your expert eye on the issue been following for a long time including your home. UK

Your welcome sir work safe you scare me sometimes climbing around .1 fall would be aweful to you or ya crew members .
You can tell how hard a guys working by his Swiss cheesed gloves lol
Designing my next root cellar build. Considering this same system, only cold water. Hoping with a cold water circulating in the slab, and cold air from pipes buried 5' down and warm air drawn from the ceiling, maybe I can hit 40 degrees. Thoughts? Maybe run the walls as well?
Have you done radiant runs in a spiral vs the back and forth and if so have you seen a performance delta? I have seen the center of the slab left uninsulated and the perimeter dug down 24+ and heavily insulated creating a larger battery, do you have thoughts on that? Do you have any detail on anticipated costs to install and power to run? Thoughts on bigger pipe, thicker slabs, more insulation? Appreciate these great videos, not near enough information out there.
Also, how would Styrofoam infused aircrete work vs sprayfoam for fitting to the gravel bed?
Awesome videos! Thank you! Do you have any problem with increase in cracking of your garage floors because of the foam? I have radiant in my basement, but I don’t know if I want to put it in my garage because I am afraid of it sagging or cracking with weight of the vehicles.

No as long as you prep all your below grade properly you shouldn’t have excess cracking.
Have you considered using a foil backed foam board for your radiant install? Foil would be more effective at reflecting the heat upward to your slab. I say that because most types of radiant installs use some type of plate or reflective insulation to reflect the heat in the direction you want heat additionally it has a higher R value which would pay for itself over time.

Yes is the cost usually. But when he says closed cell base is the way to go I agree. You're killing two birds with 1 stone and a better result with a total seal

Heat transfer here from the tubing into the slab is by conduction, not sure that adding foil is any help in spaces with very little air (unlike an attic, open crawl space, garage door, etc.).

There have been studies showing the use of a reflective barrier under a slab is not effective. It won’t harm anything, but it’s not useful spending. One of the bigger boiler companies shared this
Can't tell if you're using PEX A or PEX B real question is why would you not use the expansion tool for PEX A? Just looking for pros and cons figure the expense may be good investment For a DYIer and for freezing, not necessarily not necessarily for the inground/in concrete radiant floor yet I'm looking at a 1 inch pipe going from a water source to a holding tank and then back down to the house thing the expence of the tools with proof handy
If you live in a climate that doesn't get really cold for long periods of time, could you do 4'-6' of pex just around the exterior walls and still keep the entire house warm?
@bpdp379

Yes but it’d me extremely inefficient. The whole slab works together as a storage system of the heat. If you only had tubing at the perimeter it’d still be trying to heat all the concrete (remember concrete is horrible at resisting heat transfer) but with maybe 10% of the necessary BTU/hr. This only applies to trying to heat an entire building envelope. You could heat individual rooms instead of the whole building envelope.
How does reliability and cost compare for using some sort of fiber for reinforcement vs rebar in your slab?
Actually there probably isn't any problems doing the in floor heat like that...I think the only thing I would do different is maybe use a foam board with a reflective film turned up and tape the seams with reflective tape
My heating contractor put sand down 2" foam board heat tubes and then 2 more inches of sand then the concrete guys put there rebar and concrete. heat works great.
Why XPS and not EPS. I'm hearing Conflicting opinions on that. Main argument us that EPS holds up over time to moisture better and retains more of it's R value in the end. I feel like the foam under these heated slabs will stay pretty dry if you have a few inches of gravel under it and good drainage around the building. Any thoughts on that?
I have a question for you about how you did foundation. I noticed the one you use cement columns, the other you put in solid wall & you water proof it & insulated it. Why the difference between the two. We have been You take pride in all the work you do. Tks for sharing what you do...

We used the ICF system on this build for a couple reasons...1. There was an existing foundation and that all had to be removed a dug out. Wanted to make sure we had a solid foundation in undisturbed soil. 2. There is a lot of limestone in the area so it would have made it tough drilling holes with auger. If you have time to watch the first few episodes of this playlist I go into more detail of the reasons for choosing the ICF foundation over the cement piers. kzread.info/head/PL3QM32YjSVn24Y0jGrwYcGQ1--0ACLiRN
Can you put wire mesh over top of the pex tubes?
For a single zone pole barn approximately 1600sqft, would there be any reason not to use 1000ft rolls of led for each run?
I agree 6mill is fine! Just don't tear it

What determines a zone?
What size is gravel? 3/4 inch? Thanks!
No RADON ventilation?

I noticed around 8:28 you went right through what looks to be a bathroom. Should you avoid toilets and under bathtub areas? What about under kitchen cabinets and refrigerators?

keep pex tubing at least 12" from toilets so you don't melt the wax ring.

is post frame cheaper to put up than stick frame on average?
@MrPostFrame
Жыл бұрын
It really depends on what your building. The real money savings is foundation and sheathing roof and walls. With post frame you save money if you do concrete piers vs a continuous footing. Additionally you save money because you don’t have to sheath your roof or sidewalls. The building gets its shear strength from the metal so there isn’t a need to sheet those areas like stick build. There are other areas but those are the two biggest money saving areas.
