Sill insulation under interior wall?

[Nygge72]

Hi, do you use/what do you use under interior walls that rest on the concrete slab?

I assume you need to protect these as well from moisture from the slab, and I'm wondering if you also use sill insulation there or if you use something else on interior walls that are not load-bearing?

Thanks in advance.

Sheet metal rail is a simple and quick way to install new interior walls on concrete floors (works for both wood and metal studs)

Yes, you should have that, but there are cheaper and simpler options for interior walls like this one which usually comes in 70, 95, and 120mm widths.
As the simplest option, you can use age-resistant plastic.

As the simplest option, you can lay down age-resistant plastic..

I'm thinking it should also act as soundproofing since I've read that these insulations seal sound. So how does this compare to Isover Vario, for example? I think that since this is something you typically do once, there's no reason to save a few bucks if it means the overall quality is much better with soundproof spaces, etc.

Feels like it could transport sound between better than if you use some type of insulation, right?

The metal tracks have insulation underneath so they become airtight.

You probably won't notice the sound as long as the frame is tight against the concrete...

If there is so much moisture in the concrete, there are probably major problems with the entire foundation.

What do you mean?

If there is so much moisture in the slab that you can't attach the inner wall sole directly to the concrete, then the foundation probably wasn't done properly.

If there is so much moisture in the slab that you cannot attach the inner wall sill directly to the concrete, then the foundation has probably not been done properly.

But all newly built concrete slabs contain a lot of moisture and all organic material should be protected when in contact with concrete.

Didn't think of that!
That you don't let the concrete slab dry completely before installing interior walls and floors.
I'm building without being a stressed contractor, so my slab was allowed to dry at its own pace.

Didn't think of that!
Not letting the concrete slab dry completely before putting up interior walls and laying floors.
I'm building without being a stressed contractor, so my slab was allowed to dry in peace.

But even if you dry it out, there should be protection between wood and concrete..

Feels like a small cost in the long run for a safer construction.

Everyone does it as they want, just a little wondering if it's really necessary if you have a really good foundation with capillary-breaking material, drainage, insulation, and especially if you have a radonmata.
