Building an interior wall on a floating floor

[mattiasohult]

I am renovating a villa from '79. The villa has a concrete slab and has had a floating floor. In part of the house, the interior wall studs have been placed directly on the concrete slab, but almost everywhere, the interior wall studs have been placed on the subflooring of the floating floor.

Now I wonder if I can place the new interior walls on the subflooring of the floating floor? The floor heating will also be installed in the subflooring, if that makes any difference.

Do you mean that the chipboard flooring is floating (can move) and is not fixed to anything?

What are your thoughts regarding the underfloor heating?

What are your thoughts on the underfloor heating?

Exactly, or rather, that's how it was before. I plan to continue that way if possible

I'm thinking concrete slab, Styrofoam, 22mm chipboard with milled underfloor heating, 12mm chipboard, vinyl click

I believe that if you install interior walls on chipboard flooring, the boards are no longer floating but locked in place. It should still be possible to continue doing so. However, you shouldn't have underfloor heating beneath the interior walls; instead, each room should have its own loop.

I'm thinking that some rooms might share a loop. For example, 2 bedrooms and an office that are on the same end share a loop.

How does it affect if the loop goes under the wall?

I'm thinking that maybe you don't have to attach the sill to the floor chipboard?

I think that some rooms might share a circuit. For example, 2 bedrooms and an office on the same side of the house sharing a circuit.

That's less ideal the day no one lives in the bedrooms anymore and you want to keep them at 16 degrees in the winter to save money, while the office is still in use and you want to have it at 20 degrees there.

It is less ideal the day no one lives in the bedrooms anymore and you want to maintain 16 degrees in them during winter to save money while the office is still used and you want to have 20 degrees there.

maybe so, but it feels like you save that cost by not having to purchase 2 extra room sensors, larger manifolds, extra tubing, etc.

Anyone else have any thoughts on this?

Exactly, or rather, that's how it has looked before. I was thinking of continuing with that, if possible


I'm thinking concrete slab, cellular plastic, 22mm floor chipboard with milled underfloor heating, 12mm floor chipboard, vinyl click

Have you tried going with such a solution? Feels to me like it might feel strange, but I've never tried it.

No, not at all

The previous floor was, as mentioned, concrete slab, cellular plastic, 22mm chipboard, laminate flooring

I think it should be the same if you add a 12mm chipboard on it.

Anyone?
