Hello TH-cam! If you guys enjoyed this, please do check out my other videos of the farmhouse restoration - at the moment we're working on gutting and replacing an old rotten oak roof, far more exciting than concrete and insulation in my humble opinion... Also, please do subscribe to the channel, I'm posting twice a month at the moment but would love to ramp that up if people enjoy!
Hello friend, I would like to know what is the purpose of the insulating plates that they install at the beginning, since I observe that later they put concrete on top. Very good channel and I will appreciate your response. Cheers
in the village i live there's a street where a drunk guy on his bike (back in the 70's) rode thru wet concrete, zigzagging all the way to his house. :D
Been screeding over 30 years now, never laid a screed on bare insulation boards ever, polythene is cheap and will save you 20% UV value, as the cement destroys the reflective foil .Other than that , perfect video,thumbs up.
@@z8Nation yes i have always put a barrier between cement and insulation boards, you dont have to tape board joints also it stops joints following through the screed, reducing cracking.
@@z8Nation put like this I'm just putting in a similar floor in 2021. Architectural plans stipulate vapour check membrane over insulation boards before scree.
I SO L O V E,. that property.!! I'm drawn to old stone houses in France; almost obsessed.. LOL.. must be in my DNA. My 8th Great grandfarther, Francois Belanger came from the Normandy area.' he came over to Quebec Canada (New France) in 1635.. I guess it's good he did, or I wouldn't be here.. haha.. You are amazing.. love your work.. thanks for sharing it..!
With Ryan's th-cam.com/users/postUgkxy_pn55PK60wAV3X_C_RoLS_67mNonoCE plan I was like one taken by the hand and led step by step from start to finish. Thank you very much Ryan!
flooring and drywall is probably where I'll always leave it to it's own professionals, it requires a lot of experience, a diy person can do 90% of the work, but the last 10% is what gets noticed, my dad "used to say 20% money gets you 80% of the work".
very nice, but here we usually put forged in the concrete to prevent it from cracking. Has not been sunk or broken with the passage of a year? great work equally
quick question - how would you run central heating pipes to radiators now the floor is concrete and walls solid brick? I noticed you had cut out sections in the insulation boards for electric cables - could you have done the same for running pipework (might be silly question)
Hello. I noticed the house we purchased the extention attached to the house - the flooring does not have insulation. There is a membrane and 4" concrete on the floor. However is there an option i could insalate the floor before we decide to put either laminate or carpet down? Thanks in advance
Have a look at a German company called GUTEX, you'll need a membrane to stop moisture passing through, especially if the concrete slab is bridging and allowing moisture to pass through
The job could have been improved by closing the gaps between the insulation boards with some gun foam and taping the joints of the top layer. Also a PE membrane should have gone on top to protect the aluminium foil, cement is caustic and reacts very well with aluminium, so it eats trough, the membrane also acts as a vapour barrier. You gave up on the cat exploring this big litter box 😂?
If that was pex plumbing that the insulation was laid over top of... why would you put contrete/mortar on the floor as your subfloor to make it permanently inaccessible?
Thanks for the video. Wasn't it necessary to tape the joints, usually done with aluminium tape? Also shouldn't a moisture barrier have been put down before the screed? I understand the screed can chemically react with the PIR surface.
Hi hope you are well, if you only had a small area like 1m x 1.5m and didnt have access to a mechanical mixer, how would you go about mixing the screed? Thanks
Great video Carl. Few questions about your screed... your tiling video says '3 weeks' after screeding. Thought that seemed a bit soon, but what sort of temperature was the screed cured in? Also what was the mix? 4:1? Any additives in the water?
This is the first in a series that I have found on TH-cam but it doesn’t seem to start at the beginning. Who are you, and where are you at and where are you from? Why are you doing this and what are your plans? I just found you on TH-cam and can’t find any background on what is going on. Please help!
Hello! What did you lay down as a dpc or something to stop the moisture barrier? I assume this is a true old building and it's solid walls would not have a barrier at the base layer. It would be great to explain the initial methods to the process. Have you done something to stop moisture from the base floor? Looks like you had some initial concrete layer before the thick insulation boards.
Honest question from over in the US, what advantages are there to using this method ( low hydration Portland sand mix 1/5 or so guessing ?) To just pumping in some concrete?
No need to tape the insulation seams when using this method to keep the moisture from penetrating? No need for a wire mesh in the screed mix to keep it all stable? I guess the floor just floats or does it sit on some kind of foundation that supports the stone walls?
стыки полистирольных плит можно было проклеить скотчем простым - не забивался бы раствор и не образовывались бы мостики холода. И простую сетку проволочную для армировки почему не использовали? большая площадь бетона без армировки-это плохо. Получается, это была полусухая бетонная стяжка. А маяки-как уровень стяжки регулировался? Примерно на глаз?
Supersesqui i did give that a thought too we have to put 100mm upstand round the walls and there is usually 2 layers of dpm. First layer under the concrete then your insulation then dpm then screed. But i cant imagine there will be any problems with it i think building control measures are over the top sometimes but i have heard the concrete rots the insulation....
that is why the top layer has to be thick this looks like about 70mm thick - so the load at the piano legs is spread over many square metres of insulation
160 mm of what looks to be hard foam (pir/resol?). That's an immense amount of isolation. Rd of around 8 or so? Why so much? Or is it different stuff? Looks like a beautiful place though!
Jelte Arntzen no, I think you’re right. My dad likes to do things over the top...”belt and braces”..... but it does get very cold here in winter and we won’t have central heating
Very handy men! Great work and excellent video, no club music, no unnecessary "explanations". I'm not familiar with that insulation , however I would have used thin set mortar to set it on the subfloor and I would've used thin set mortar between it and the dry pack (mix) bed also. Anyway, I'm sure it lasts for many years! Good job, again!
I wondered if foam concrete could offer an equivalent insulation quality compared to this conventional method of installing insulation panels topped with cement mortar screed surface?
Have been taken by the idea of foamed concrete, but it looks much softer. So I'd have thought you may need to then top with something else. Not that I can grok u values. Perhaps someone would post a comparison including thickness.
That type of insulation board is now standard insulation required by UK planning regs. .....so we're hoping it's gonna last a few life times at least...fingers crossed.
in the UK we have been doing this for about the last 25 years and failures are very rare, so long as the top layer is sensibly thick to act as a load spreader. This looks like about 70mm
Apenas uma pergunta! O porquê de colocar essas placas no chão antes de fazer o piso? Seria pra fazer algum tipo de isolamento contra umidade? Pois, se for pra isso não tem necessidade alguma disso pois, uma lona antes já é o suficiente
Hi Carl you may have just solved a problem my old kicthen is 5 inchs lower and tiled onto hard core . Can I use this solution to raise the floor and tile then put my kitchen floor units on top ? what sort of strength have these boards ? i was looking for wedi boards and this cameup - is the concept the same? thanks

carlrogers hi Carl, brilliant video, what is the mix of the screed? Thanks keep it going Luke 👍
Hi Carl, Great videos. How can we contact you? We have a project you may be interested in helping us out with.
La mezcla está hecha en base a arena y cemento solamente??
Hello friend, I would like to know what is the purpose of the insulating plates that they install at the beginning, since I observe that later they put concrete on top. Very good channel and I will appreciate your response. Cheers
Si ha ten
This is how a video should be done...great presentation without any bullsh*t
thank you sir!
It was nice to see the cat doing its job as supervisor and inspecting the flooring to see it was up to code.
Whenever there's fresh concrete, there's a cat.
Sometimes dog
harzfier it’s the law lol
in the village i live there's a street where a drunk guy on his bike (back in the 70's) rode thru wet concrete, zigzagging all the way to his house. :D
Thats why you have BB guns
Or a fox!
The cat supervising is the best of the video.
Haha what a nuisance
Videos like this makes construction GREAT AGAIN
Been screeding over 30 years now, never laid a screed on bare insulation boards ever, polythene is cheap and will save you 20% UV value, as the cement destroys the reflective foil .Other than that , perfect video,thumbs up.
So you recommend putting a polythene sheet down before you cement on top of the insulation boards?
@@z8Nation yes i have always put a barrier between cement and insulation boards, you dont have to tape board joints also it stops joints following through the screed, reducing cracking.
@@z8Nation put like this I'm just putting in a similar floor in 2021. Architectural plans stipulate vapour check membrane over insulation boards before scree.
@@sanjikaspinoni8396 How long will a 65mm screed takes to dry after applying it on the insulation board, although using a membrane.
@@graceakinje4965 Dry usually 48 hours. 6-7 days before ready for heavy traffic...but always check on your I individual product advice.

Found your channel by accident. Love it. Currently working my way through start to finish. Very enjoyable. Very nicely done. Keep posting!
Wow this guys work so fast!!! Better than the cowboys I hired.
Bloody heck that's so well insulated I bet it's hard to breath
Ahhh so that's the trick to using music without getting a copyright claim: speeding it up 800%
Thanks for the tip ;)
Just found your channel and am really enjoying your work.
That intro shot! Very nice, love it!
NO, BUT SERIOUSLY, LOVE YOUR WORK. NICE KNEE PADS!
Should there not be a membrane under the insulation before you lay it?
Beneath the insulation bro
Almost 2 years, doubters comments lament the cracking of the floor within a year....please tell me its absolutely sound as a pound! 😇👍
sound as a pound!!!
@@carlroge Yeeeeehh hahaha. Bloody love it. Well done. Xxx
outstanding advice to building a garage
thanks for uploading/posting that type of video, but till us about the wall repairing of your farmhouse

@fartpoobox ohyeah it is called the perato principle.
Haha brilliant love it - I wish I could work this fast :D
Nice, what's under the insulation? Any moisture barriers? And are those cables lost forever?
Yep Cables lost forever.
Have you a video of the prep work of the floor? Going to tackle a French barn!
very nice, but here we usually put forged in the concrete to prevent it from cracking.
Has not been sunk or broken with the passage of a year?
great work equally
this place looks like an old castle!
Without the need for insulation, would the screed need to be bonded to existing floor or can it be laid directly onto the floor?
Look at that cement mixer go !
If the sub floor was soil, what would go in-between the soil and the insulation boards?
Hi, you could put a layer of sand, called blinding, then boards on top, followed by dpm then screed
Novice here!! May I ask if when you have levelled it that’s it? Do you add a liquid form of cement on top or do you leave it as this sand mixture?
quick question - how would you run central heating pipes to radiators now the floor is concrete and walls solid brick? I noticed you had cut out sections in the insulation boards for electric cables - could you have done the same for running pipework (might be silly question)

No mention of the material used on the floor?

Like the safety sliders!
What is it with dogs and cats and fresh cement?
cat be like "lemme check your freshly poured concrete floor"
Not concrete . It is floor screed . i.e. sand and cement.
@@hannecatton2179 lmao, thank you for correcting me professor
How long did you wait for the screed to dry before tiling?
You forgot to tape the joints of the insulation... It is a small detail but makes a huge difference in preventing leaks and vapor

😀😋😂😂😋😘😎😍😎😎😎
What is under the insulation? - looks like a concrete floor. If it is an earth floor, how did you seal it?
Carl, what are the screed mud mix ratios ?
Great video and great work! Awesome channel :D

Hi there gd vid but out of curiosity why didn't you tape the joints
Nice job respect from morocco
Ciekawy jestem po ten beton mieszacie jeszcze raz... I szacun za tą wylewkę bo bez rurek koleś ładnie to wyciągnął
Your channel is very interesting
question? Why did you not install some wire or steel rebar in this floor?
Are those steel toe cap flip flops
haha
#safetyflipflops
Cool video and process. New to me!
Cheers Sebastian
Honest question from over in the US, what advantages are there to using this method ( low hydration Portland sand mix 1/5 or so guessing ?) To just pumping in some concrete?
Cheaper
yup, just cheaper..
No need to tape the insulation seams when using this method to keep the moisture from penetrating? No need for a wire mesh in the screed mix to keep it all stable? I guess the floor just floats or does it sit on some kind of foundation that supports the stone walls?
Wasn't the underfloor concrete?
Pai kore, mate. Dad's a dab hand with that float.
haha, will let him know!
Can I put this insulation directly on top of loose sand and then put screed over the insulation?
Hi, Why was grooved cut into the plasterboard please?
Good evening. After the screed how long to I need to wait before laying a laminated floor.
Excellent work, well done. New subscriber here.
Great sound effects

The styrofoam insulation sawing nearly killed me 🙉
what's is the advantage of this insulation sheet in flooring
insulating the floor helps keep warmth within the room/building
carlrogers are there other type or options of insulating materials?
eguonor akpomudjere jablight buried within the cement and membrane itself
Hello! Why would you need the insulation and what material is it made of?
So 100mm then 80mm, would putting down 150mm insulation first be sufficient
Why did you not install under - floor heating ?
what about rising humidity, does it affect the insulation boards?
No DPM under insulation or 100 mm up walls ?
supersesqui there's membrane under the concrete pad, below the insulation.
carlrogers is there not supposed to be also above so the screed doesn't rot the rigid insulation board...????
Supersesqui i did give that a thought too we have to put 100mm upstand round the walls and there is usually 2 layers of dpm. First layer under the concrete then your insulation then dpm then screed. But i cant imagine there will be any problems with it i think building control measures are over the top sometimes but i have heard the concrete rots the insulation....
do they have building regs in France ?
What happens if you put something heavy on it like a piano? Wouldn't it sink in after a while?
that is why the top layer has to be thick this looks like about 70mm thick - so the load at the piano legs is spread over many square metres of insulation
sorry in my country we don´t do that. that insulation is for what? does it prevent wet? or is a termical insulation?
keeps your feet warmer in the winter. also under the original red floor below, we hope, is either a tar or plastic damp proof layer
Lo bueno es que hay un gato de interventor de obra para que el trabajo no quede mal hecho
Membrane on top of celotex ,and up the walls mate

Good work, sir
What mix are you using for screed 4:1, and what type of sand? Is any brand cement fine or are you using a particular type? Thanks for Vid
Are those steel toe-cap sliders? 😉
No vapour barrier under the insulation??
no band of insulation separating it from the wall ?
You know they are pro builders when they turn up to work in adidas sliders 😳
Perfect, thanx. How much that screed weighs per m2 ?
I watch these @ 2x speed, on acid, it's the correct speed.
No VCL or foam buffer round the edges??
Very handy men! Great work and excellent video, no club music, no unnecessary "explanations".

Have been taken by the idea of foamed concrete, but it looks much softer. So I'd have thought you may need to then top with something else. Not that I can grok u values. Perhaps someone would post a comparison including thickness.
So it looks like you put foam padding under concrete.
I wonder how this turns out long term?
its a sand/ cement screed not concrete and the insulation will be made out of a plastic material so they will last long enough :)
That type of insulation board is now standard insulation required by UK planning regs. .....so we're hoping it's gonna last a few life times at least...fingers crossed.
in the UK we have been doing this for about the last 25 years and failures are very rare, so long as the top layer is sensibly thick to act as a load spreader. This looks like about 70mm
