Hello!
I am about to start framing inner walls in our renovation project. I have poured a slab with underfloor heating, and although the water pipes for the underfloor heating are directly against the insulation in the slab (the slab is 10cm thick so I should have at least 7cm before hitting the water pipes), which means I could technically drill and screw the base plate into the concrete, I am not going to do that. I do NOT want to risk drilling through any water pipes. But I have heard and read that it is equally effective to glue the base plate (45*95) to the slab. My question is: I want the best possible sound insulation and therefore would like to have EPDM rubber between the base plate and the slab, but will it work if I glue it? Can I glue the EPDM rubber to the base plate first and let it dry, and then glue it to the slab, or how would you do it?

You must have insulation between the sill and the slab. Rubber or rather plastic is probably the most common nowadays. The sill does not need to be fixed vertically since the wall rests on it, but it must be fixed laterally. It is sufficient to get the anchor bolt or plug a few cm down into the slab for this. Construction adhesive should also work.
If you want a quiet wall, you should go for double gypsum. It is the weight of the wall that dampens vibrations.
