Frame wall on parquet and insulate correctly?

[ivan82]

Can you put up a wall on a parquet floor? Or should I cut the parquet where the wall will start so that the parquet has room to expand?

I am going to have a sliding door on the inside of the wall, how do I soundproof it correctly?

From inside out (Closest to the sliding door):
Plywood board
Construction plastic
Insulation 45mm
Construction plastic
Plywood
Gypsum

Glue a metal rail with double-sided tape on the parquet, so you don't have to screw it in if you want to remove it sometime in the future and frame up the wall. You shouldn't put plastic in the wall when it's indoors, and never double plastic in any wall (as this traps moisture).

The part against the door can be soundproofed with a 50 mm foam board instead, so you don't need to put plywood behind it. OSB works behind drywall if you want to save some money...
