Underfloor heating in Sparse Panel or Grooved chipboard

MathiasS · 1 Mar 2015 at 5:00 PM

Nah, of course, you've placed the chipboard in the wrong place. It should be on the beams, not on top of the pipes.

I thought so too, but I found construction principle on Uponor's website, and Uponor calculated loops, etc., based on that principle.
Planning to build again now, and I'm thinking of using grooved particle boards.

I placed sparse on top of the plank floor and floor gypsum on it. It became a rather solid joist structure 😌

If it is waterborne heating, there must be a plastic film/moisture barrier between the pipes and the floor; otherwise, there is a risk that the floor will absorb water/moisture.

I realize I was a bit unclear... I have placed 22mm floor chipboard on the beams, then I cut strips of 19mm chipboard which were screwed and glued and laid as sparse paneling. Then sheets, pipe floor gypsum which was screwed and glued then vapor barrier and parquet.

No, the floor does not absorb moisture. You have plastic so that the top and bottom of the floor live in the same environment as much as possible, thereby reducing the risk of the floor becoming warped. It's about ensuring it is EQUALLY moist everywhere, not less moist...

Then you might want to call Uponor and ask

It is not Uponor you should ask, it is the flooring manufacturer.

Then you can call them too

We got that explanation from both the flooring manufacturers and Uponor.
There will be condensation and that condensation affects the parquet floor. We used a foam that was plasticized on one side. Convenient as you have everything in one.

MathiasS · 6 Mar 2015 at 11:48 AM

I have spoken with both and received other more reasonable answers. IF it actually is the case that condensation forms as you say, it would be a disaster to put in plastic. Where do you think the water goes then? Crooked floors are the last thing you need to worry about in that situation.

Well, it's not leakage we're talking about

It's the plates that distribute the heat.

MathiasS · 6 Mar 2015 at 5:03 PM

Leaks and plates? I don't understand what that has to do with plastic film, why are you talking about it? Or better yet, don't answer, let's just drop it...

Hi!
It's been a while since you wrote this, but since I'm planning to do exactly the same, I wonder how it has worked out for you?
Do you remember the thickness of the tubing you used?

Pärran · 7 Dec 2020 at 12:44 PM

It has worked well and I find our floor structure to be quieter and more solid than the other houses we socialize in. I use 16mm hose.
