Attaching sill to concrete ?

[tupas]

I am going to install an interior wall in my garage. Now I am wondering what is the best way to attach the sole plate to the concrete slab? (insulated slab) Do you need to have some type of plastic under the sole plate when it is directly on the concrete?

Screw + plug is enough. Place a strip of tjärpapp under the sill, then it will be really good.

Do you need tar paper when it's an interior wall?
Do you hammer down the nail plug or do you screw it down? It looks like threads on it.

Pre-drill according to dowel size -- then hit it with the hammer....done
Use tar paper even though moisture travels....
Best regards

You can probably use age-resistant plastic film just as well as roofing felt, underlayment felt, sill paper, or foam sill insulation. (As mentioned, there are many alternatives)
Perhaps roofing felt or foam strips provide somewhat more protection against free-flowing water on the floor, as the sill will be a few mm higher from the floor.

But some form of moisture insulation is strongly recommended, unless the wall is purely a temporary thing that will be removed within a year or so.

Moisture insulation of some kind, absolutely. Syllpapp or tjärpapp. I don't believe in plastic film, it's too thin.
Spikplugg is hammered in and screwed when you remove it, hence the threads.

If there is underfloor heating, it's not much fun to drill into the slab. I've used adhesive + tar paper + adhesive + sill.

Steel or wood sill?

We attach all sills with expansion bolts, or through bolts as they are also called:

10mm sill insulation under steel sills, plastic sheeting under wood.

Can't one use age-resistant plastic film instead of syllpapp?

Steel or wooden sill?

We attach all sills with anchor bolts, also known as through bolts:

Outer wall - anchor bolt. YES.
Inner wall - anchor bolt, well. I also don't hunt mosquitoes with a shotgun...
But sure, it works...

Can't you use age-resistant plastic film instead of sillpapp?

You can, but as someone mentioned, there is a high risk of it getting perforated. However, if you have a lot of foil left and it's a long way to the sillpapp store, you can just fold it several times.

Outer wall - expansion bolt. YES.
Inner wall - expansion bolt, well. I don't hunt mosquitoes with a shotgun either ...
But it can be done ...

If it's supposed to stay, it should
