I'm planning to frame an interior wall. I'm thinking of using a steel track directly on the concrete slab. But I'm hesitant to screw into the slab because of the underfloor heating, so I'm considering gluing it instead. Is it okay to do that? What adhesive should be used for this purpose?

The track I'm considering has 4 mm polyethylene under it (like a plastic strip, for better sound insulation?), does that create a weak link? Should I go without polyethylene so the adhesive bonds directly to the steel?
 
Remove the polyethylene underneath and glue with something like tec7 or superfix, which has worked well for me many times, but don't skimp on the glue. Then, if you want good acoustic properties for the wall, seal between the first and second layer of boards on both sides of the wall. The fabric underneath is to make the wall airtight under the track, which is essentially replaced with the glue, but you'll get better results by sealing. If you want to further secure the wall so it is fastened to the floor, tighten the wooden studs against the ceiling.

Great, thanks for the answer. Do you have experience with how easy it is to remove polyethylene?

It usually works well to carve with the knife and pull off
 
there are stålutlägg without polyeten, buy those instead. Then glue them with Tec7

I plan to do something similar, namely to build a storage room in my carport with a concrete slab. (Pink marking on the picture). I'm wondering if anyone has done this and if they have used steel or wooden studs. It will be outdoors, but under a roof.

I also don't want to screw the studs down because I might remove the storage in a few years, and I have embedded underfloor heating pipes for potential future use.

Should I use barrier paper under the sills? And if so, does it affect the adhesion of the sills to the floor?

Steel does not need a sill membrane as it is not sensitive to moisture.
