we do similar job almost every site in S.Korea, since slab heat on the slab or subfloor is basic heating way in here , which is called 'on-dol'. if radiation pipes set on that foam, the heat only goes for the living space, not warming the subfloor or slab. you can add fasteners to make sure the foam won't detached on the floor. Thank you for the hepful videos, I always enjoy watching them.
23:37 you could also leave the stair out but add in a pressure treated plate where the stringers will eventually land. The trick is to put the plate in the right spot to pass the load thru to the slab and to make it the correct height so that it’s either flush to the top adventech layer or flush to the top of the foam layer. I kind of think flush to the top would be better but it would work either way and reduce the amount and size of obstacles to be cut around.
Wow. I help a friend of mine who owns a flooring company. I don't think he watches your channel. I'm a learning builder and have gotten a lot of information and even been able to practice. Homestead life. This is the best flooring system ever. Wow. Talk about belt and suspenders. I was wondering how you would install hardwood flooring because of those big staples. Two sheets of plywood over the foamboard will do work. I have a large shed. I turned part of it into my outdoor office/ mancave. I had some 3/4in hickory that I installed in there. That's coming up. I'm gonna insulate the floor now. I got the walls and ceiling done with 2.5in polyiso and there was an instant difference. Great job. Great thought. Great material. Great video. You guys are on it.
Agreed. If this is a major remodel and that’s an existing concrete floor but other than that I’d think under would be better. Would be quieter with the slab top insulation though, and be less thermo mass for the hvac to work with. Just throwing ideas out there.
@librogrande The goal is to insulate against thermal gain of solar on the concrete-in Texas we aren’t trying to insulate against the ground as much as the heat sink that the slab becomes when the sun beats down on it
The other benefit is that even though the floor is stiff, it does have SOME cushion, which makes the assembly easier on your joints in the long run vs walking on flooring that is directly on concrete.
The vast majority of your slab and rhe earth beneath it is shaded by the house. In a hot climate like Texas and Florida where 90% of the time you are cooling, being coupled to the cooler soil is an energy saver. Insulating the perimeter of the slab from the surrounding "hot" soil might make some sense if you're fanatical about it. Insulated slabs in cooler climates make sense.
What framing details do you need to do to account for something like this? Double bottom plates and adjusted bottom stair riser to make up for the height difference?
Actually, he said “… on the Risinger Build” referring to the specific project he’s showcasing in this series. I don’t think it’s going to replace the classic sign off-at least I hope not 😊.
Would there be any code issues putting in a floor outlet on that floating floor? They make boxes thin enough? Seems like a good opportunity to add a floor outlet without busting up concrete.
Hi Matt. Have you ever used the UFO ballistic nails for your flooring? I was wondering if they would be a good in-between of nails and screws in subfloors. Cheers
My crawlspace is not conditioned. Can I put this product on my subfloor then put a second subfloor over it. I plan to tile the floor down the road. Thanks!
Matt, I wonder if the furring strips add much over just using a product like Cedar Breather for your air gap. Wondering for my own house mainly, but what is the incremental benefit?
Building in a flood prone area causes insurance rates to go up for everyone. Insurance companies should not spread this cost out. Owners of homes that flood periodically should take the full brunt of the costs based on their risk factors. That would prevent building in high risk areas if rates are 10X more than a non-flood prone area. Where I live, there is almost zero chance of flooding from overflowing bodies of water. Tornadoes are weak and infrequent and no risk of wildfires, yet our rates keep going up based on high risk areas being slammed by storms and rising sea levels, which are going to get worse over time and more expensive.
Building our new cabinet shop would this work to add some spring back into the floor? Everyone complains about working on the hard concrete floors all day in our current shop.
No one is commenting the potential vapor issues? R10 isn't that high, and it's safe bet that slab will be colder than the inside of the house by a fair enough amount that the dew point will be on the slab itself...then where does all the moisture go? NONE of those insulation seams are taped, so there WILL BE vapor condensing between that rigid foam and the slab. Would love to see that floor torn up in 10 years and see what's growing under there.
how would you insulate a raised floor house? previous owner put some styrofoam type board under the subfloor but it broke apart and came off under the house
yea cuz ive been working so hard lately u could use a couple days to get off my high horse i guess. good thing were off campus grounds now. so what u say we sit under that peach tree there and have us a lunchable?
Hi Matt, My name is Simon. I'm trying to design my dream home, I'm arranging studs. I really need your help on deciding whether stud positions should be more convenient for framing or boarding and drywalling ? Should I make it easier for the framing team with the cost of difficulty for drywall team or the other way around ? Please let me know your opinion !
Just one quick question. If a house has this sort of subflooring on the first floor, what happens if it gets flooded? Probably not a bit concern in Austin, but definitely would be a concern in Houston.
I am building a new House with a slab. It seems easier to insulate beneath the slab. Then put a sleeper for with 2x4's (flat over the slab) then cover with 1 layer of advantech? Any thoughts?
Two layers of subflooring just seems redundant. Particularly with that insulation board. I wonder sometimes if we all aren't just adding more parts than we need. I mean it wasn't too long ago people were getting crazy complicated with their rainscreens and now it's mostly all boiled down to a pliable open weave rainscreen material with an 1/8" to 1/4" air gap etc.
slap+foam+two staggered layers of the subfloor are necessary to prevent defection and movement. Otherwise, all flooring or tiles will move/deform/crack over time bc of too much movement.
@@thomascho3318 not seen that in my case and if the floating floor is done right it has plenty of room to move all along the perimeter, plus, these days many floating floors are so highly laminated with resins the movement is very small. It's not like one is accounting for solid hardwood wood movement in these products.
Really a great system for energy efficiency but I hope you never experience a flood in your home. When you have a flood you've got to remove all materials down to the slab. You'd be into some major surgery here.
techincally it's not that much overkill. The only overkill would be one additional Advantech. It could be replaced with a standard OSB subfloor. But overall, slap+foam+two staggered layers of the subfloor are necessary to prevent defection and movement. Otherwise, all flooring or tiles will move/deform/crack over time bc of too much movement.
The constant product pitching gets a bit much at times, I understand they are giving you loads of free products and you have to do your part by selling them to your viewers, but it does start to feel like I'm watching a 30 minute advert. I heard you the 14th time you said it, Energy shield XR, Advantech Subfloor.
Again, "Build Styles of the Rich and Famous". We know you get paid by all the products you "recommend", but maybe after you make your million$$, you could show how to build a house that the blue collar masses, that probably make up most of your viewers, could actually afford?!! Just a thought.

Great job Bill and crew. 👍
Great video Matt....amazing energy efficient details 👌 👍 ✨️

Why not insulate under the slab on grade (instead of on top) - and get benefit of thermal mass?
Agreed. If this is a major remodel and that’s an existing concrete floor but other than that I’d think under would be better. Would be quieter with the slab top insulation though, and be less thermo mass for the hvac to work with. Just throwing ideas out there.

On this house, there was a previous slab they went over top of. So he couldn't go under.

Bro, I can’t even see those white feet on that new concrete!😂😂😂
I love the Ready-Frame product but hate the fact that BFS won't deliver for single-build homes here in Houston, Texas.
What framing details do you need to do to account for something like this? Double bottom plates and adjusted bottom stair riser to make up for the height difference?
Was wondering the same thing
I was waiting for, "On the build show" sign off. Now the new sign off is, "On the risinger show". I like the old way.
Actually, he said “… on the Risinger Build” referring to the specific project he’s showcasing in this series. I don’t think it’s going to replace the classic sign off-at least I hope not 😊.
I wanna see more about this "Slap Top" @20:08
Would there be any code issues putting in a floor outlet on that floating floor? They make boxes thin enough? Seems like a good opportunity to add a floor outlet without busting up concrete.
They do make thin enough boxes, but it will not be flush with the floor when done.
Hi Matt. Have you ever used the UFO ballistic nails for your flooring? I was wondering if they would be a good in-between of nails and screws in subfloors. Cheers
There should be ZIP-R sub flooring. 😉
Can you put in floor / radiant heating on top of this?
Do you leave room for expansion at plates?
My crawlspace is not conditioned. Can I put this product on my subfloor then put a second subfloor over it. I plan to tile the floor down the road. Thanks!
Hey Matt, maybe you can help Bill scale up/crew up😅 Get Bill his own channel. I need more framing videos from Bill & his team.
Matt, I wonder if the furring strips add much over just using a product like Cedar Breather for your air gap. Wondering for my own house mainly, but what is the incremental benefit?
If you lived in an area with potential to flood do to hurricanes. Would you still recommend this type of flooding?
It’s better to not build in a flood prone area.
Building in a flood prone area causes insurance rates to go up for everyone. Insurance companies should not spread this cost out. Owners of homes that flood periodically should take the full brunt of the costs based on their risk factors. That would prevent building in high risk areas if rates are 10X more than a non-flood prone area. Where I live, there is almost zero chance of flooding from overflowing bodies of water. Tornadoes are weak and infrequent and no risk of wildfires, yet our rates keep going up based on high risk areas being slammed by storms and rising sea levels, which are going to get worse over time and more expensive.
Don't use any structure that traps water. I wouldn't recommend it. You will have a very tough time getting the NFIP to pay if it is ever damaged.

Show us THE BURN TEST on that poly-iso insulation product.
Awesome!
What are your thoughts on Uponor PexA Red are you concerned about all the houses you out it in?
Matt, are you going to use Steller Flooring?
yea cuz ive been working so hard lately u could use a couple days to get off my high horse i guess. good thing were off campus grounds now. so what u say we sit under that peach tree there and have us a lunchable?
How are you fastening your non load bearing walls to the floor and ceiling?
How does one deal with the inevitable water infiltration on this assembly?
Hi Matt, My name is Simon.

Triple bottom plate next time? Are you planning on blocking for baseboard?
If I'm in an area that's predominantly hot, I'll take the heat loss in the winter if the cool slab adds comfort during the summer

It's called overkill for no reason. I love quality and done right, this is simply overkill
Any chance you’ll review Uponor Xpress Track for hydronic heating above grade?
Only if upinor pays for an ad. The best products are the ones who pay the Build show the most money
Really a great system for energy efficiency but I hope you never experience a flood in your home. When you have a flood you've got to remove all materials down to the slab. You'd be into some major surgery here.
Why would you use this system instead of insulation under the slab?
Like a site built zip r panel for your floor.
Grab bars should be standard in all showers for safety for all ages.
Why you donc went some Radeon concrete floor , so you can safe a lot of money
I love learning from this channel, but this was a 30 minute advertisement.
Slab + Stego + Slab + Foam + Advantech + Advantech + Flooring = OVERKILL!
techincally it's not that much overkill. The only overkill would be one additional Advantech. It could be replaced with a standard OSB subfloor. But overall, slap+foam+two staggered layers of the subfloor are necessary to prevent defection and movement. Otherwise, all flooring or tiles will move/deform/crack over time bc of too much movement.
Why do you need the expense of advantech especially with the first layer of you are already water tight build
They didnt glue the first two layers
Only $1000/sqft

Americans learning about floor insulation xD. I had mine done in 1999 in Poland.
Jeez, can I say overkill on the subfloor 🙄
Seems like a bit of overkill.....will dramatically increase construction costs.
A lot of rich people out there in Texas 🤠
I'm gonna assume he wanted a true wood flooring and you can't do that over a concrete slab.

Imagine walking your customers on sight with an apple vision pro on.
Polyiso? I won’t spec that toxic crap any more.
