Frame interior walls

[NiclasR]

Then it's soon time to start thinking about framing the interior walls on our upper floor.

When I've read a bit about this particular job, some recommend using some form of rubber mat/insulation mat. This mat should be clamped under/behind the studs when attaching them to the floor, ceiling, and support walls. I assume it's about reducing sound transmission through the wall construction.

How is it usually done in practice?

You don't mean syllremsa, which is used between the foundation and the walls? It is meant to prevent moisture from rising into the sill and to stop drafts/insulate. But maybe you can use a rubber strip in interior walls too if you're afraid that structure-borne sound will propagate too much.

works excellently, better I think is the approximately 3mm thick roll in sleeping mat quality
have used both for interior walls against the btg floor

Well, when I extended the garage, I used a sealing strip of tar paper-like quality specifically to stop moisture and drafts.

But in this case, when I'm going to install interior walls on the upper floor, I don't think there should be either moisture or drafts.

So the reason I can see is using some form of strip to stop sound, if it's needed?

One might wonder if it has much effect if there's an interior door in the middle of the wall?

The strip is used to make the construction more tight to reduce the transmission of airborne sound. The door in the middle of the wall, however, is probably more determining depending on quality, of course...

Yes, then maybe you should place a strip under the inner wall.

What is this type of strip usually called?
Then I can check if the building supplier has any in stock and what it costs.
